    WARNING: This interface is likely to change in order to accomodate https://github.com/emberjs/rfcs/pull/4
  
    ## Using BuildURLMixin
  
    To use url building, include the mixin when extending an adapter, and call `buildURL` where needed.
    The default behaviour is designed for RESTAdapter.
  
    ### Example
  
    ```javascript
    export default DS.Adapter.extend(BuildURLMixin, {
      findRecord: function(store, type, id, snapshot) {
        var url = this.buildURL(type.modelName, id, snapshot, 'findRecord');
        return this.ajax(url, 'GET');
      }
    });
    ```
  
    ### Attributes
  
    The `host` and `namespace` attributes will be used if defined, and are optional.
  
    @class BuildURLMixin
    @namespace DS
  */
  exports.default = _ember.default.Mixin.create({

      becomes 'posts' and 'person' becomes 'people'). To override the
      pluralization see [pathForType](#method_pathForType).
       If an ID is specified, it adds the ID to the path generated
      for the type, separated by a `/`.
       When called by RESTAdapter.findMany() the `id` and `snapshot` parameters
      will be arrays of ids and snapshots.

    A `ManyArray` is a `MutableArray` that represents the contents of a has-many
    relationship.
  
    The `ManyArray` is instantiated lazily the first time the relationship is
    requested.
  
    ### Inverses
  
    Often, the relationships in Ember Data applications will have
    an inverse. For example, imagine the following models are
    defined:
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      comments: DS.hasMany('comment')
    });
    ```
  
    ```app/models/comment.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      post: DS.belongsTo('post')
    });
    ```
  
    If you created a new instance of `App.Post` and added
    a `App.Comment` record to its `comments` has-many
    relationship, you would expect the comment's `post`
    property to be set to the post that contained
    the has-many.
  
    We call the record to which a relationship belongs the
    relationship's _owner_.

  /**
    Holds validation errors for a given record, organized by attribute names.
  
    Every `DS.Model` has an `errors` property that is an instance of
    `DS.Errors`. This can be used to display validation error
    messages returned from the server when a `record.save()` rejects.
  
    For Example, if you had a `User` model that looked like this:
  
    ```app/models/user.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      username: attr('string'),
      email: attr('string')
    });
    ```
    And you attempted to save a record that did not validate on the backend:
  
    ```javascript
    var user = store.createRecord('user', {
      username: 'tomster',
      email: 'invalidEmail'
    });
    user.save();
    ```
  
    Your backend would be expected to return an error response that described
    the problem, so that error messages can be generated on the app.
  
    API responses will be translated into instances of `DS.Errors` differently,
    depending on the specific combination of adapter and serializer used. You
    may want to check the documentation or the source code of the libraries
    that you are using, to know how they expect errors to be communicated.
  
    Errors can be displayed to the user by accessing their property name
    to get an array of all the error objects for that property. Each
    error object is a JavaScript object with two keys:
  
    - `message` A string containing the error message from the backend
    - `attribute` The name of the property associated with this error message
  
    ```handlebars
    <label>Username: {{input value=username}} </label>
    {{#each model.errors.username as |error|}}
      <div class="error">
        {{error.message}}
      </div>
    {{/each}}
  
    <label>Email: {{input value=email}} </label>
    {{#each model.errors.email as |error|}}
      <div class="error">
        {{error.message}}
      </div>
    {{/each}}
    ```
  
    You can also access the special `messages` property on the error
    object to get an array of all the error strings.
  
    ```handlebars
    {{#each model.errors.messages as |message|}}
      <div class="error">
        {{message}}
      </div>
    {{/each}}

    `InternalModel` is the Model class that we use internally inside Ember Data to represent models.
    Internal ED methods should only deal with `InternalModel` objects. It is a fast, plain Javascript class.
  
    We expose `DS.Model` to application code, by materializing a `DS.Model` from `InternalModel` lazily, as
    a performance optimization.
  
    `InternalModel` should never be exposed to application code. At the boundaries of the system, in places
    like `find`, `push`, etc. we convert between Models and InternalModels.

        Ember Data has 3 buckets for storing the value of an attribute on an internalModel.
         `_data` holds all of the attributes that have been acknowledged by
        a backend via the adapter. When rollbackAttributes is called on a model all
        attributes will revert to the record's state in `_data`.
         `_attributes` holds any change the user has made to an attribute
        that has not been acknowledged by the adapter. Any values in
        `_attributes` are have priority over values in `_data`.
         `_inFlightAttributes`. When a record is being synced with the
        backend the values in `_attributes` are copied to
        `_inFlightAttributes`. This way if the backend acknowledges the
        save but does not return the new state Ember Data can copy the
        values from `_inFlightAttributes` to `_data`. Without having to
        worry about changes made to `_attributes` while the save was
        happenign.
          Changed keys builds a list of all of the values that may have been
        changed by the backend after a successful save.
         It does this by iterating over each key, value pair in the payload
        returned from the server after a save. If the `key` is found in
        `_attributes` then the user has a local changed to the attribute
        that has not been synced with the server and the key is not
        included in the list of changed keys.
      
        If the value, for a key differs from the value in what Ember Data
        believes to be the truth about the backend state (A merger of the
        `_data` and `_inFlightAttributes` objects where
        `_inFlightAttributes` has priority) then that means the backend
        has updated the value and the key is added to the list of changed

  /*
    This file encapsulates the various states that a record can transition
    through during its lifecycle.
  */
  /**
    ### State
  
    Each record has a `currentState` property that explicitly tracks what
    state a record is in at any given time. For instance, if a record is
    newly created and has not yet been sent to the adapter to be saved,
    it would be in the `root.loaded.created.uncommitted` state.  If a
    record has had local modifications made to it that are in the
    process of being saved, the record would be in the
    `root.loaded.updated.inFlight` state. (This state paths will be
    explained in more detail below.)
  
    Events are sent by the record or its store to the record's
    `currentState` property. How the state reacts to these events is
    dependent on which state it is in. In some states, certain events
    will be invalid and will cause an exception to be raised.
  
    States are hierarchical and every state is a substate of the
    `RootState`. For example, a record can be in the
    `root.deleted.uncommitted` state, then transition into the
    `root.deleted.inFlight` state. If a child state does not implement
    an event handler, the state manager will attempt to invoke the event
    on all parent states until the root state is reached. The state
    hierarchy of a record is described in terms of a path string. You
    can determine a record's current state by getting the state's
    `stateName` property:
  
    ```javascript
    record.get('currentState.stateName');
    //=> "root.created.uncommitted"
     ```
  
    The hierarchy of valid states that ship with ember data looks like
    this:
  
    ```text
    * root
      * deleted
        * saved
        * uncommitted
        * inFlight
      * empty
      * loaded
        * created
          * uncommitted
          * inFlight
        * saved
        * updated
          * uncommitted
          * inFlight
      * loading
    ```
  
    The `DS.Model` states are themselves stateless. What that means is
    that, the hierarchical states that each of *those* points to is a
    shared data structure. For performance reasons, instead of each
    record getting its own copy of the hierarchy of states, each record
    points to this global, immutable shared instance. How does a state
    know which record it should be acting on? We pass the record
    instance into the state's event handlers as the first argument.
  
    The record passed as the first parameter is where you should stash
    state about the record if needed; you should never store data on the state
    object itself.
  
    ### Events and Flags
  
    A state may implement zero or more events and flags.
  
    #### Events
  
    Events are named functions that are invoked when sent to a record. The
    record will first look for a method with the given name on the
    current state. If no method is found, it will search the current
    state's parent, and then its grandparent, and so on until reaching
    the top of the hierarchy. If the root is reached without an event
    handler being found, an exception will be raised. This can be very
    helpful when debugging new features.
  
    Here's an example implementation of a state with a `myEvent` event handler:
  
    ```javascript
    aState: DS.State.create({
      myEvent: function(manager, param) {
        console.log("Received myEvent with", param);
      }
    })
    ```
  
    To trigger this event:
  
    ```javascript
    record.send('myEvent', 'foo');
    //=> "Received myEvent with foo"
    ```
  
    Note that an optional parameter can be sent to a record's `send()` method,
    which will be passed as the second parameter to the event handler.
  
    Events should transition to a different state if appropriate. This can be
    done by calling the record's `transitionTo()` method with a path to the
    desired state. The state manager will attempt to resolve the state path
    relative to the current state. If no state is found at that path, it will
    attempt to resolve it relative to the current state's parent, and then its
    parent, and so on until the root is reached. For example, imagine a hierarchy
    like this:
  
        * created
          * uncommitted <-- currentState
          * inFlight
        * updated
          * inFlight
  
    If we are currently in the `uncommitted` state, calling
    `transitionTo('inFlight')` would transition to the `created.inFlight` state,
    while calling `transitionTo('updated.inFlight')` would transition to
    the `updated.inFlight` state.
  
    Remember that *only events* should ever cause a state transition. You should
    never call `transitionTo()` from outside a state's event handler. If you are
    tempted to do so, create a new event and send that to the state manager.
  
    #### Flags
  
    Flags are Boolean values that can be used to introspect a record's current
    state in a more user-friendly way than examining its state path. For example,
    instead of doing this:
  
    ```javascript
    var statePath = record.get('stateManager.currentPath');
    if (statePath === 'created.inFlight') {
      doSomething();
    }
    ```
  
    You can say:
  
    ```javascript
    if (record.get('isNew') && record.get('isSaving')) {
      doSomething();
    }
    ```
  
    If your state does not set a value for a given flag, the value will
    be inherited from its parent (or the first place in the state hierarchy
    where it is defined).
  
    The current set of flags are defined below. If you want to add a new flag,
    in addition to the area below, you will also need to declare it in the
    `DS.Model` class.
  
  
     * [isEmpty](DS.Model.html#property_isEmpty)
     * [isLoading](DS.Model.html#property_isLoading)

     * [isNew](DS.Model.html#property_isNew)
     * [isValid](DS.Model.html#property_isValid)

  // Implementation notes:
  //
  // Each state has a boolean value for all of the following flags:
  //
  // * isLoaded: The record has a populated `data` property. When a
  //   record is loaded via `store.find`, `isLoaded` is false
  //   until the adapter sets it. When a record is created locally,
  //   its `isLoaded` property is always true.
  // * isDirty: The record has local changes that have not yet been
  //   saved by the adapter. This includes records that have been
  //   created (but not yet saved) or deleted.
  // * isSaving: The record has been committed, but
  //   the adapter has not yet acknowledged that the changes have
  //   been persisted to the backend.
  // * isDeleted: The record was marked for deletion. When `isDeleted`
  //   is true and `isDirty` is true, the record is deleted locally
  //   but the deletion was not yet persisted. When `isSaving` is
  //   true, the change is in-flight. When both `isDirty` and
  //   `isSaving` are false, the change has persisted.
  // * isNew: The record was created on the client and the adapter
  //   did not yet report that it was successfully saved.
  // * isValid: The adapter did not report any server-side validation
  //   failures.

  // The dirty state is a abstract state whose functionality is
  // shared between the `created` and `updated` states.
  //
  // The deleted state shares the `isDirty` flag with the
  // subclasses of `DirtyState`, but with a very different
  // implementation.
  //
  // Dirty states have three child states:
  //
  // `uncommitted`: the store has not yet handed off the record
  //   to be saved.
  // `inFlight`: the store has handed off the record to be saved,
  //   but the adapter has not yet acknowledged success.
  // `invalid`: the record has invalid information and cannot be

    #### One-To-One
    To declare a one-to-one relationship between two models, use

    You can avoid passing a string as the first parameter. In that case Ember Data

  /**
    `DS.hasMany` is used to define One-To-Many and Many-To-Many
    relationships on a [DS.Model](/api/data/classes/DS.Model.html).
  
    `DS.hasMany` takes an optional hash as a second parameter, currently
    supported options are:
  
    - `async`: A boolean value used to explicitly declare this to be an async relationship.
    - `inverse`: A string used to identify the inverse property on a related model.
  
    #### One-To-Many
    To declare a one-to-many relationship between two models, use
    `DS.belongsTo` in combination with `DS.hasMany`, like this:
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      comments: DS.hasMany('comment')
    });
    ```
  
    ```app/models/comment.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      post: DS.belongsTo('post')
    });
    ```
  
    #### Many-To-Many
    To declare a many-to-many relationship between two models, use
    `DS.hasMany`:
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      tags: DS.hasMany('tag')
    });
    ```
  
    ```app/models/tag.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      posts: DS.hasMany('post')
    });
    ```
  
    You can avoid passing a string as the first parameter. In that case Ember Data
    will infer the type from the singularized key name.
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      tags: DS.hasMany()
    });
    ```
  
    will lookup for a Tag type.
  
    #### Explicit Inverses
  
    Ember Data will do its best to discover which relationships map to
    one another. In the one-to-many code above, for example, Ember Data
    can figure out that changing the `comments` relationship should update
    the `post` relationship on the inverse because post is the only
    relationship to that model.
  
    However, sometimes you may have multiple `belongsTo`/`hasManys` for the
    same type. You can specify which property on the related model is
    the inverse using `DS.hasMany`'s `inverse` option:
  
    ```app/models/comment.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      onePost: DS.belongsTo('post'),
      twoPost: DS.belongsTo('post'),
      redPost: DS.belongsTo('post'),
      bluePost: DS.belongsTo('post')
    });
    ```
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      comments: DS.hasMany('comment', {
        inverse: 'redPost'
      })
    });
    ```
  
    You can also specify an inverse on a `belongsTo`, which works how
    you'd expect.

  //   The variables in this file are consistently named according to the following

  //
  //   * +id+ means an identifier managed by an external source, provided inside
  //     the data provided by that source. These are always coerced to be strings
  //     before being used internally.
  //   * +clientId+ means a transient numerical identifier generated at runtime by
  //     the data store. It is important primarily because newly created objects may
  //     not yet have an externally generated id.
  //   * +internalModel+ means a record internalModel object, which holds metadata about a
  //     record, even if it has not yet been fully materialized.
  //   * +type+ means a DS.Model.

  /**
    The store contains all of the data for records loaded from the server.
    It is also responsible for creating instances of `DS.Model` that wrap
    the individual data for a record, so that they can be bound to in your
    Handlebars templates.
  
    Define your application's store like this:
  
    ```app/services/store.js
    import DS from 'ember-data';
  
    export default DS.Store.extend({
    });
    ```
  
    Most Ember.js applications will only have a single `DS.Store` that is
    automatically created by their `Ember.Application`.
  
    You can retrieve models from the store in several ways. To retrieve a record
    for a specific id, use `DS.Store`'s `findRecord()` method:
  
    ```javascript
    store.findRecord('person', 123).then(function (person) {
    });
    ```
  
    By default, the store will talk to your backend using a standard
    REST mechanism. You can customize how the store talks to your
    backend by specifying a custom adapter:
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.Adapter.extend({
    });
    ```
  
    You can learn more about writing a custom adapter by reading the `DS.Adapter`
    documentation.
  
    ### Store createRecord() vs. push() vs. pushPayload()
  
    The store provides multiple ways to create new record objects. They have
    some subtle differences in their use which are detailed below:
  
    [createRecord](#method_createRecord) is used for creating new
    records on the client side. This will return a new record in the
    `created.uncommitted` state. In order to persist this record to the
    backend you will need to call `record.save()`.
  
    [push](#method_push) is used to notify Ember Data's store of new or
    updated records that exist in the backend. This will return a record
    in the `loaded.saved` state. The primary use-case for `store#push` is
    to notify Ember Data about record updates (full or partial) that happen
    outside of the normal adapter methods (for example
    [SSE](http://dev.w3.org/html5/eventsource/) or [Web
    Sockets](http://www.w3.org/TR/2009/WD-websockets-20091222/)).
  
    [pushPayload](#method_pushPayload) is a convenience wrapper for
    `store#push` that will deserialize payloads if the
    Serializer implements a `pushPayload` method.
  
    Note: When creating a new record using any of the above methods
    Ember Data will update `DS.RecordArray`s such as those returned by
    `store#peekAll()`, `store#findAll()` or `store#filter()`. This means any
    data bindings or computed properties that depend on the RecordArray
    will automatically be synced to include the new or updated record
    values.

    /**
      This method returns a record for a given type and id combination.
       The `findRecord` method will always resolve its promise with the same
      object for a given type and `id`.
       The `findRecord` method will always return a **promise** that will be
      resolved with the record.
       Example
       ```app/routes/post.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
          return this.store.findRecord('post', params.post_id);
        }
      });
      ```
       If the record is not yet available, the store will ask the adapter's `find`
      method to find the necessary data. If the record is already present in the
      store, it depends on the reload behavior _when_ the returned promise
      resolves.
       ### Reloading
       The reload behavior is configured either via the passed `options` hash or
      the result of the adapter's `shouldReloadRecord`.
       If `{ reload: true }` is passed or `adapter.shouldReloadRecord` evaluates
      to `true`, then the returned promise resolves once the adapter returns
      data, regardless if the requested record is already in the store:
       ```js
      store.push({
        data: {
          id: 1,
          type: 'post',
          revision: 1
        }
      });
       // adapter#findRecord resolves with
      // [
      //   {
      //     id: 1,
      //     type: 'post',
      //     revision: 2
      //   }
      // ]
      store.findRecord('post', 1, { reload: true }).then(function(post) {
        post.get("revision"); // 2
      });
      ```
       If no reload is indicated via the abovementioned ways, then the promise
      immediately resolves with the cached version in the store.
       ### Background Reloading
       Optionally, if `adapter.shouldBackgroundReloadRecord` evaluates to `true`,
      then a background reload is started, which updates the records' data, once
      it is available:
       ```js
      // app/adapters/post.js
      import ApplicationAdapter from "./application";
       export default ApplicationAdapter.extend({
        shouldReloadRecord(store, snapshot) {
          return false;
        },
         shouldBackgroundReloadRecord(store, snapshot) {
          return true;
        }
      });
       // ...
       store.push({
        data: {
          id: 1,
          type: 'post',
          revision: 1
        }
      });
       let blogPost = store.findRecord('post', 1).then(function(post) {
        post.get('revision'); // 1
      });
       // later, once adapter#findRecord resolved with
      // [
      //   {
      //     id: 1,
      //     type: 'post',
      //     revision: 2
      //   }
      // ]
       blogPost.get('revision'); // 2
      ```
       If you would like to force or prevent background reloading, you can set a
      boolean value for `backgroundReload` in the options object for
      `findRecord`.
       ```app/routes/post/edit.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
          return this.store.findRecord('post', params.post_id, { backgroundReload: false });
        }
      });
      ```
      If you pass an object on the `adapterOptions` property of the options
     argument it will be passed to you adapter via the snapshot
       ```app/routes/post/edit.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
          return this.store.findRecord('post', params.post_id, {
            adapterOptions: { subscribe: false }
          });
        }
      });
      ```
       ```app/adapters/post.js
      import MyCustomAdapter from './custom-adapter';
       export default MyCustomAdapter.extend({
        findRecord: function(store, type, id, snapshot) {
          if (snapshot.adapterOptions.subscribe) {
            // ...
          }
          // ...
        }
      });
      ```
       See [peekRecord](#method_peekRecord) to get the cached version of a record.
       ### Retrieving Related Model Records
       If you use an adapter such as Ember's default
      [`JSONAPIAdapter`](http://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html)
      that supports the [JSON API specification](http://jsonapi.org/) and if your server
      endpoint supports the use of an
      ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
      you can use `findRecord()` to automatically retrieve additional records related to
      the one you request by supplying an `include` parameter in the `options` object.
       For example, given a `post` model that has a `hasMany` relationship with a `comment`
      model, when we retrieve a specific post we can have the server also return that post's
      comments in the same request:
       ```app/routes/post.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
         return this.store.findRecord('post', params.post_id, {include: 'comments'});
        }
      });
       ```
      In this case, the post's comments would then be available in your template as
      `model.comments`.
       Multiple relationships can be requested using an `include` parameter consisting of a
      comma-separated list (without white-space) while nested relationships can be specified
      using a dot-separated sequence of relationship names. So to request both the post's
      comments and the authors of those comments the request would look like this:
       ```app/routes/post.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
         return this.store.findRecord('post', params.post_id, {include: 'comments,comments.author'});
        }
      });
       ```

      This method makes a request for one record, where the `id` is not known
      beforehand (if the `id` is known, use [`findRecord`](#method_findRecord)
      instead).
       This method can be used when it is certain that the server will return a
      single object for the primary data.
       Let's assume our API provides an endpoint for the currently logged in user
      via:
       ```
      // GET /api/current_user
      {
        user: {
          id: 1234,
          username: 'admin'
        }
      }
      ```
       Since the specific `id` of the `user` is not known beforehand, we can use
      `queryRecord` to get the user:
       ```javascript
      store.queryRecord('user', {}).then(function(user) {
        let username = user.get('username');
        console.log(`Currently logged in as ${username}`);
      });
      ```
       The request is made through the adapters' `queryRecord`:
       ```app/adapters/user.js
      import DS from "ember-data";
       export default DS.Adapter.extend({
        queryRecord(modelName, query) {
          return Ember.$.getJSON("/api/current_user");
        }
      });
      ```
       Note: the primary use case for `store.queryRecord` is when a single record
      is queried and the `id` is not known beforehand. In all other cases
      `store.query` and using the first item of the array is likely the preferred
      way:
       ```
      // GET /users?username=unique
      {
        data: [{
          id: 1234,
          type: 'user',
          attributes: {
            username: "unique"
          }
        }]
      }
      ```
       ```javascript
      store.query('user', { username: 'unique' }).then(function(users) {
        return users.get('firstObject');
      }).then(function(user) {
        let id = user.get('id');
      });
      ```
       This method returns a promise, which resolves with the found record.
       If the adapter returns no data for the primary data of the payload, then
      `queryRecord` resolves with `null`:
       ```
      // GET /users?username=unique
      {
        data: null
      }
      ```
       ```javascript
      store.queryRecord('user', { username: 'unique' }).then(function(user) {
        console.log(user); // null
      });
      ```

      `findAll` asks the adapter's `findAll` method to find the records for the
      given type, and returns a promise which will resolve with all records of
      this type present in the store, even if the adapter only returns a subset
      of them.
       ```app/routes/authors.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
          return this.store.findAll('author');
        }
      });
      ```
       _When_ the returned promise resolves depends on the reload behavior,
      configured via the passed `options` hash and the result of the adapter's
      `shouldReloadAll` method.
       ### Reloading
       If `{ reload: true }` is passed or `adapter.shouldReloadAll` evaluates to
      `true`, then the returned promise resolves once the adapter returns data,
      regardless if there are already records in the store:
       ```js
      store.push({
        data: {
          id: 'first',
          type: 'author'
        }
      });
       // adapter#findAll resolves with
      // [
      //   {
      //     id: 'second',
      //     type: 'author'
      //   }
      // ]
      store.findAll('author', { reload: true }).then(function(authors) {
        authors.getEach("id"); // ['first', 'second']
      });
      ```
       If no reload is indicated via the abovementioned ways, then the promise
      immediately resolves with all the records currently loaded in the store.
       ### Background Reloading
       Optionally, if `adapter.shouldBackgroundReloadAll` evaluates to `true`,
      then a background reload is started. Once this resolves, the array with
      which the promise resolves, is updated automatically so it contains all the
      records in the store:
       ```js
      // app/adapters/application.js
      export default DS.Adapter.extend({
        shouldReloadAll(store, snapshotsArray) {
          return false;
        },
         shouldBackgroundReloadAll(store, snapshotsArray) {
          return true;
        }
      });
       // ...
       store.push({
        data: {
          id: 'first',
          type: 'author'
        }
      });
       let allAuthors;
      store.findAll('author').then(function(authors) {
        authors.getEach('id'); // ['first']
         allAuthors = authors;
      });
       // later, once adapter#findAll resolved with
      // [
      //   {
      //     id: 'second',
      //     type: 'author'
      //   }
      // ]
       allAuthors.getEach('id'); // ['first', 'second']
      ```
       If you would like to force or prevent background reloading, you can set a
      boolean value for `backgroundReload` in the options object for
      `findAll`.
       ```app/routes/post/edit.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function() {
          return this.store.findAll('post', { backgroundReload: false });
        }
      });
      ```
       If you pass an object on the `adapterOptions` property of the options
      argument it will be passed to you adapter via the `snapshotRecordArray`
       ```app/routes/posts.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function(params) {
          return this.store.findAll('post', {
            adapterOptions: { subscribe: false }
          });
        }
      });
      ```
       ```app/adapters/post.js
      import MyCustomAdapter from './custom-adapter';
       export default MyCustomAdapter.extend({
        findAll: function(store, type, sinceToken, snapshotRecordArray) {
          if (snapshotRecordArray.adapterOptions.subscribe) {
            // ...
          }
          // ...
        }
      });
      ```
       See [peekAll](#method_peekAll) to get an array of current records in the
      store, without waiting until a reload is finished.
       ### Retrieving Related Model Records
       If you use an adapter such as Ember's default
      [`JSONAPIAdapter`](http://emberjs.com/api/data/classes/DS.JSONAPIAdapter.html)
      that supports the [JSON API specification](http://jsonapi.org/) and if your server
      endpoint supports the use of an
      ['include' query parameter](http://jsonapi.org/format/#fetching-includes),
      you can use `findAll()` to automatically retrieve additional records related to
      those requested by supplying an `include` parameter in the `options` object.
       For example, given a `post` model that has a `hasMany` relationship with a `comment`
      model, when we retrieve all of the post records we can have the server also return
      all of the posts' comments in the same request:
       ```app/routes/posts.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function() {
         return this.store.findAll('post', {include: 'comments'});
        }
      });
       ```
      Multiple relationships can be requested using an `include` parameter consisting of a
      comma-separated list (without white-space) while nested relationships can be specified
      using a dot-separated sequence of relationship names. So to request both the posts'
      comments and the authors of those comments the request would look like this:
       ```app/routes/posts.js
      import Ember from 'ember';
       export default Ember.Route.extend({
        model: function() {
         return this.store.findAll('post', {include: 'comments,comments.author'});
        }
      });
       ```
       See [query](#method_query) to only get a subset of records from the server.

    /**
      Push some data for a given type into the store.
       This method expects normalized [JSON API](http://jsonapi.org/) document. This means you have to follow [JSON API specification](http://jsonapi.org/format/) with few minor adjustments:
      - record's `type` should always be in singular, dasherized form
      - members (properties) should be camelCased
       [Your primary data should be wrapped inside `data` property](http://jsonapi.org/format/#document-top-level):
       ```js
      store.push({
        data: {
          // primary data for single record of type `Person`
          id: '1',
          type: 'person',
          attributes: {
            firstName: 'Daniel',
            lastName: 'Kmak'
          }
        }
      });
      ```
       [Demo.](http://ember-twiddle.com/fb99f18cd3b4d3e2a4c7)
       `data` property can also hold an array (of records):
       ```js
      store.push({
        data: [
          // an array of records
          {
            id: '1',
            type: 'person',
            attributes: {
              firstName: 'Daniel',
              lastName: 'Kmak'
            }
          },
          {
            id: '2',
            type: 'person',
            attributes: {
              firstName: 'Tom',
              lastName: 'Dale'
            }
          }
        ]
      });
      ```
       [Demo.](http://ember-twiddle.com/69cdbeaa3702159dc355)
       There are some typical properties for `JSONAPI` payload:
      * `id` - mandatory, unique record's key
      * `type` - mandatory string which matches `model`'s dasherized name in singular form
      * `attributes` - object which holds data for record attributes - `DS.attr`'s declared in model
      * `relationships` - object which must contain any of the following properties under each relationships' respective key (example path is `relationships.achievements.data`):
        - [`links`](http://jsonapi.org/format/#document-links)
        - [`data`](http://jsonapi.org/format/#document-resource-object-linkage) - place for primary data
        - [`meta`](http://jsonapi.org/format/#document-meta) - object which contains meta-information about relationship
       For this model:
       ```app/models/person.js
      import DS from 'ember-data';
       export default DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
         children: DS.hasMany('person')
      });
      ```
       To represent the children as IDs:
       ```js
      {
        data: {
          id: '1',
          type: 'person',
          attributes: {
            firstName: 'Tom',
            lastName: 'Dale'
          },
          relationships: {
            children: {
              data: [
                {
                  id: '2',
                  type: 'person'
                },
                {
                  id: '3',
                  type: 'person'
                },
                {
                  id: '4',
                  type: 'person'
                }
              ]
            }
          }
        }
      }
      ```
       [Demo.](http://ember-twiddle.com/343e1735e034091f5bde)
       To represent the children relationship as a URL:
       ```js
      {
        data: {
          id: '1',
          type: 'person',
          attributes: {
            firstName: 'Tom',
            lastName: 'Dale'
          },
          relationships: {
            children: {
              links: {
                related: '/people/1/children'
              }
            }
          }
        }
      }
      ```
       If you're streaming data or implementing an adapter, make sure
      that you have converted the incoming data into this form. The
      store's [normalize](#method_normalize) method is a convenience
      helper for converting a json payload into the form Ember Data
      expects.
       ```js
      store.push(store.normalize('person', data));
      ```

    An adapter is an object that receives requests from a store and
    translates them into the appropriate action to take against your
    persistence layer. The persistence layer is usually an HTTP API, but
    may be anything, such as the browser's local storage. Typically the
    adapter is not invoked directly instead its functionality is accessed
    through the `store`.
  
    ### Creating an Adapter
  
    Create a new subclass of `DS.Adapter` in the `app/adapters` folder:
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.Adapter.extend({
      // ...your code here
    });
    ```
  
    Model-specific adapters can be created by putting your adapter
    class in an `app/adapters/` + `model-name` + `.js` file of the application.
  
    ```app/adapters/post.js
    import DS from 'ember-data';
  
    export default DS.Adapter.extend({
      // ...Post-specific adapter code goes here
    });
    ```
  
    `DS.Adapter` is an abstract base class that you should override in your
    application to customize it for your backend. The minimum set of methods
    that you should implement is:
  
      * `findRecord()`
      * `createRecord()`
      * `updateRecord()`
      * `deleteRecord()`
      * `findAll()`
      * `query()`
  
    To improve the network performance of your application, you can optimize
    your adapter by overriding these lower-level methods:
  
      * `findMany()`
  
  
    For an example implementation, see `DS.RESTAdapter`, the
    included REST adapter.
  
    @class Adapter

      a model specific serializer (i.e. `PostSerializer`) or the
      `application` serializer.

      the updateRecord promise can also resolve with `undefined` and the

    A `DS.AdapterError` is used by an adapter to signal that an error occurred
    during a request to an external API. It indicates a generic error, and
    subclasses are used to indicate specific error states. The following
    subclasses are provided:
  
    - `DS.InvalidError`
    - `DS.TimeoutError`
    - `DS.AbortError`
    - `DS.UnauthorizedError`
    - `DS.ForbiddenError`
    - `DS.NotFoundError`
    - `DS.ConflictError`
    - `DS.ServerError`
  
    To create a custom error to signal a specific error state in communicating
    with an external API, extend the `DS.AdapterError`. For example if the
    external API exclusively used HTTP `503 Service Unavailable` to indicate
    it was closed for maintenance:
  
    ```app/adapters/maintenance-error.js
    import DS from 'ember-data';
  
    export default DS.AdapterError.extend({ message: "Down for maintenance." });
    ```
  
    This error would then be returned by an adapter's `handleResponse` method:
  
    ```app/adapters/application.js
    import DS from 'ember-data';
    import MaintenanceError from './maintenance-error';
  
    export default DS.JSONAPIAdapter.extend({
      handleResponse(status) {
        if (503 === status) {
          return new MaintenanceError();
        }
  
        return this._super(...arguments);
      }
    });
    ```
  
    And can then be detected in an application and used to send the user to an
    `under-maintenance` route:
  
    ```app/routes/application.js
    import Ember from 'ember';
    import MaintenanceError from '../adapters/maintenance-error';
  
    export default Ember.Route.extend({
      actions: {

  /**
    A `DS.InvalidError` is used by an adapter to signal the external API
    was unable to process a request because the content was not
    semantically correct or meaningful per the API. Usually this means a
    record failed some form of server side validation. When a promise
    from an adapter is rejected with a `DS.InvalidError` the record will
    transition to the `invalid` state and the errors will be set to the
    `errors` property on the record.
  
    For Ember Data to correctly map errors to their corresponding
    properties on the model, Ember Data expects each error to be
    a valid json-api error object with a `source/pointer` that matches
    the property name. For example if you had a Post model that
    looked like this.
  
    ```app/models/post.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      title: DS.attr('string'),
      content: DS.attr('string')
    });
    ```
  
    To show an error from the server related to the `title` and
    `content` properties your adapter could return a promise that
    rejects with a `DS.InvalidError` object that looks like this:
  
    ```app/adapters/post.js
    import Ember from 'ember';
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      updateRecord: function() {
        // Fictional adapter that always rejects
        return Ember.RSVP.reject(new DS.InvalidError([
          {
            detail: 'Must be unique',
            source: { pointer: '/data/attributes/title' }
          },
          {
            detail: 'Must not be blank',
            source: { pointer: '/data/attributes/content'}
          }
        ]));
      }
    });
    ```
  
    Your backend may use different property names for your records the
    store will attempt extract and normalize the errors using the
    serializer's `extractErrors` method before the errors get added to
    the the model. As a result, it is safe for the `InvalidError` to
    wrap the error payload unaltered.

    The `JSONAPIAdapter` is the default adapter used by Ember Data. It
    is responsible for transforming the store's requests into HTTP
    requests that follow the [JSON API](http://jsonapi.org/format/)
    format.
  
    ## JSON API Conventions
  
    The JSONAPIAdapter uses JSON API conventions for building the url
    for a record and selecting the HTTP verb to use with a request. The
    actions you can take on a record map onto the following URLs in the
    JSON API adapter:
  
  <table>
    <tr>
      <th>
        Action
      </th>
      <th>
        HTTP Verb
      </th>
      <th>
        URL
      </th>
    </tr>
    <tr>
      <th>
        `store.findRecord('post', 123)`
      </th>
      <td>
        GET
      </td>
      <td>
        /posts/123
      </td>
    </tr>
    <tr>
      <th>
        `store.findAll('post')`
      </th>
      <td>
        GET
      </td>
      <td>
        /posts
      </td>
    </tr>
    <tr>
      <th>
        Update `postRecord.save()`
      </th>
      <td>
        PATCH
      </td>
      <td>
        /posts/123
      </td>
    </tr>
    <tr>
      <th>
        Create `store.createRecord('post').save()`
      </th>
      <td>
        POST
      </td>
      <td>
        /posts
      </td>
    </tr>
    <tr>
      <th>
        Delete `postRecord.destroyRecord()`
      </th>
      <td>
        DELETE
      </td>
      <td>
        /posts/123
      </td>
    </tr>
  </table>
  
    ## Success and failure
  
    The JSONAPIAdapter will consider a success any response with a
    status code of the 2xx family ("Success"), as well as 304 ("Not
    Modified"). Any other status code will be considered a failure.
  
    On success, the request promise will be resolved with the full
    response payload.
  
    Failed responses with status code 422 ("Unprocessable Entity") will
    be considered "invalid". The response will be discarded, except for
    the `errors` key. The request promise will be rejected with a
    `DS.InvalidError`. This error object will encapsulate the saved
    `errors` value.
  
    Any other status codes will be treated as an adapter error. The
    request promise will be rejected, similarly to the invalid case,
    but with an instance of `DS.AdapterError` instead.
  
    ### Endpoint path customization
  
    Endpoint paths can be prefixed with a `namespace` by setting the
    namespace property on the adapter:
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.JSONAPIAdapter.extend({
      namespace: 'api/1'
    });
    ```
    Requests for the `person` model would now target `/api/1/people/1`.
  
    ### Host customization
  
    An adapter can target other hosts by setting the `host` property.
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.JSONAPIAdapter.extend({
      host: 'https://api.example.com'
    });
    ```
  
    Requests for the `person` model would now target
    `https://api.example.com/people/1`.

        if (beforeSend) {

        }
      };

      return hash;
    },

    /**
      By default the JSONAPIAdapter will send each find request coming from a `store.find`
      or from accessing a relationship separately to the server. If your server supports passing
      ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests
      within a single runloop.
       For example, if you have an initial payload of:
       ```javascript
      {
        data: {
          id: 1,
          type: 'post',
          relationship: {
            comments: {
              data: [
                { id: 1, type: 'comment' },
                { id: 2, type: 'comment' }
              ]
            }
          }
        }
      }
      ```
       By default calling `post.get('comments')` will trigger the following requests(assuming the
      comments haven't been loaded before):
       ```
      GET /comments/1
      GET /comments/2
      ```
       If you set coalesceFindRequests to `true` it will instead trigger the following request:
       ```
      GET /comments?filter[id]=1,2
      ```
       Setting coalesceFindRequests to `true` also works for `store.find` requests and `belongsTo`
      relationships accessed within the same runloop. If you set `coalesceFindRequests: true`
       ```javascript
      store.findRecord('comment', 1);
      store.findRecord('comment', 2);
      ```
       will also send a request to: `GET /comments?filter[id]=1,2`
       Note: Requests coalescing rely on URL building strategy. So if you override `buildURL` in your app
      `groupRecordsForFindMany` more likely should be overridden as well in order for coalescing to work.

  /**
    The REST adapter allows your store to communicate with an HTTP server by
    transmitting JSON via XHR. Most Ember.js apps that consume a JSON API
    should use the REST adapter.
  
    This adapter is designed around the idea that the JSON exchanged with
    the server should be conventional.
  
    ## Success and failure
  
    The REST adapter will consider a success any response with a status code
    of the 2xx family ("Success"), as well as 304 ("Not Modified"). Any other
    status code will be considered a failure.
  
    On success, the request promise will be resolved with the full response
    payload.
  
    Failed responses with status code 422 ("Unprocessable Entity") will be
    considered "invalid". The response will be discarded, except for the
    `errors` key. The request promise will be rejected with a `DS.InvalidError`.
    This error object will encapsulate the saved `errors` value.
  
    Any other status codes will be treated as an "adapter error". The request
    promise will be rejected, similarly to the "invalid" case, but with
    an instance of `DS.AdapterError` instead.
  
    ## JSON Structure
  
    The REST adapter expects the JSON returned from your server to follow
    these conventions.
  
    ### Object Root
  
    The JSON payload should be an object that contains the record inside a
    root property. For example, in response to a `GET` request for
    `/posts/1`, the JSON should look like this:
  
    ```js
    {
      "posts": {
        "id": 1,
        "title": "I'm Running to Reform the W3C's Tag",
        "author": "Yehuda Katz"
      }
    }
    ```
  
    Similarly, in response to a `GET` request for `/posts`, the JSON should
    look like this:
  
    ```js
    {
      "posts": [
        {
          "id": 1,
          "title": "I'm Running to Reform the W3C's Tag",
          "author": "Yehuda Katz"
        },
        {
          "id": 2,
          "title": "Rails is omakase",
          "author": "D2H"
        }
      ]
    }
    ```
  
    Note that the object root can be pluralized for both a single-object response
    and an array response: the REST adapter is not strict on this. Further, if the
    HTTP server responds to a `GET` request to `/posts/1` (e.g. the response to a
    `findRecord` query) with more than one object in the array, Ember Data will
    only display the object with the matching ID.
  
    ### Conventional Names
  
    Attribute names in your JSON payload should be the camelCased versions of
    the attributes in your Ember.js models.
  
    For example, if you have a `Person` model:
  
    ```app/models/person.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      firstName: DS.attr('string'),
      lastName: DS.attr('string'),
      occupation: DS.attr('string')
    });
    ```
  
    The JSON returned should look like this:
  
    ```js
    {
      "people": {
        "id": 5,
        "firstName": "Barack",
        "lastName": "Obama",
        "occupation": "President"
      }
    }
    ```
  
    #### Relationships
  
    Relationships are usually represented by ids to the record in the
    relationship. The related records can then be sideloaded in the
    response under a key for the type.
  
    ```js
    {
      "posts": {
        "id": 5,
        "title": "I'm Running to Reform the W3C's Tag",
        "author": "Yehuda Katz",
        "comments": [1, 2]
      },
      "comments": [{
        "id": 1,
        "author": "User 1",
        "message": "First!",
      }, {
        "id": 2,
        "author": "User 2",
        "message": "Good Luck!",
      }]
    }
    ```
  
    If the records in the relationship are not known when the response
    is serialized its also possible to represent the relationship as a
    url using the `links` key in the response. Ember Data will fetch
    this url to resolve the relationship when it is accessed for the
    first time.
  
    ```js
    {
      "posts": {
        "id": 5,
        "title": "I'm Running to Reform the W3C's Tag",
        "author": "Yehuda Katz",
        "links": {
          "comments": "/posts/5/comments"
        }
      }
    }
    ```
  
    ### Errors
  
    If a response is considered a failure, the JSON payload is expected to include
    a top-level key `errors`, detailing any specific issues. For example:
  
    ```js
    {
      "errors": {
        "msg": "Something went wrong"
      }
    }
    ```
  
    This adapter does not make any assumptions as to the format of the `errors`
    object. It will simply be passed along as is, wrapped in an instance
    of `DS.InvalidError` or `DS.AdapterError`. The serializer can interpret it
    afterwards.
  
    ## Customization
  
    ### Endpoint path customization
  
    Endpoint paths can be prefixed with a `namespace` by setting the namespace
    property on the adapter:
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      namespace: 'api/1'
    });
    ```
    Requests for the `Person` model would now target `/api/1/people/1`.
  
    ### Host customization
  
    An adapter can target other hosts by setting the `host` property.
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      host: 'https://api.example.com'
    });
    ```
  
    ### Headers customization
  
    Some APIs require HTTP headers, e.g. to provide an API key. Arbitrary
    headers can be set as key/value pairs on the `RESTAdapter`'s `headers`
    object and Ember Data will send them along with each ajax request.
  
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      headers: {
        "API_KEY": "secret key",
        "ANOTHER_HEADER": "Some header value"
      }
    });
    ```
  
    `headers` can also be used as a computed property to support dynamic
    headers. In the example below, the `session` object has been
    injected into an adapter by Ember's container.
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      headers: Ember.computed('session.authToken', function() {
        return {
          "API_KEY": this.get("session.authToken"),
          "ANOTHER_HEADER": "Some header value"
        };
      })
    });
    ```
  
    In some cases, your dynamic headers may require data from some
    object outside of Ember's observer system (for example
    `document.cookie`). You can use the
    [volatile](/api/classes/Ember.ComputedProperty.html#method_volatile)
    function to set the property into a non-cached mode causing the headers to
    be recomputed with every request.
  
    ```app/adapters/application.js
    import DS from 'ember-data';
  
    export default DS.RESTAdapter.extend({
      headers: Ember.computed(function() {
        return {
          "API_KEY": Ember.get(document.cookie.match(/apiKey\=([^;]*)/), "1"),
          "ANOTHER_HEADER": "Some header value"
        };
      }).volatile()
    });
    ```
  
    @class RESTAdapter
    @constructor
    @namespace DS
    @extends DS.Adapter
    @uses DS.BuildURLMixin
  */
  var RESTAdapter = _emberDataAdapter.default.extend(_emberDataPrivateAdaptersBuildUrlMixin.default, {
    defaultSerializer: '-rest',

    /**
      By default, the RESTAdapter will send the query params sorted alphabetically to the
      server.
       For example:
       ```js
        store.query('posts', { sort: 'price', category: 'pets' });
      ```
       will generate a requests like this `/posts?category=pets&sort=price`, even if the
      parameters were specified in a different order.
       That way the generated URL will be deterministic and that simplifies caching mechanisms
      in the backend.
       Setting `sortQueryParams` to a falsey value will respect the original order.
       In case you want to sort the query parameters with a different criteria, set
      `sortQueryParams` to your custom sort function.
       ```app/adapters/application.js
      import DS from 'ember-data';
       export default DS.RESTAdapter.extend({
        sortQueryParams: function(params) {
          var sortedKeys = Object.keys(params).sort().reverse();
          var len = sortedKeys.length, newParams = {};
           for (var i = 0; i < len; i++) {
            newParams[sortedKeys[i]] = params[sortedKeys[i]];
          }
          return newParams;
        }
      });
      ```
       @method sortQueryParams
      @param {Object} obj
      @return {Object}
    */
    sortQueryParams: function (obj) {
      var keys = Object.keys(obj);
      var len = keys.length;
      if (len < 2) {
        return obj;
      }
      var newQueryParams = {};
      var sortedKeys = keys.sort();

      for (var i = 0; i < len; i++) {
        newQueryParams[sortedKeys[i]] = obj[sortedKeys[i]];
      }
      return newQueryParams;
    },

    /**
      By default the RESTAdapter will send each find request coming from a `store.find`
      or from accessing a relationship separately to the server. If your server supports passing
      ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests
      within a single runloop.
       For example, if you have an initial payload of:
       ```javascript
      {
        post: {
          id: 1,
          comments: [1, 2]
        }
      }
      ```
       By default calling `post.get('comments')` will trigger the following requests(assuming the
      comments haven't been loaded before):
       ```
      GET /comments/1
      GET /comments/2
      ```
       If you set coalesceFindRequests to `true` it will instead trigger the following request:
       ```
      GET /comments?ids[]=1&ids[]=2
      ```
       Setting coalesceFindRequests to `true` also works for `store.find` requests and `belongsTo`
      relationships accessed within the same runloop. If you set `coalesceFindRequests: true`
       ```javascript
      store.findRecord('comment', 1);
      store.findRecord('comment', 2);
      ```
       will also send a request to: `GET /comments?ids[]=1&ids[]=2`
       Note: Requests coalescing rely on URL building strategy. So if you override `buildURL` in your app
      `groupRecordsForFindMany` more likely should be overridden as well in order for coalescing to work.

      Organize records into groups, each of which is to be passed to separate
      calls to `findMany`.
       This implementation groups together records that have the same base URL but
      differing ids. For example `/comments/1` and `/comments/2` will be grouped together
      because we know findMany can coalesce them together as `/comments?ids[]=1&ids[]=2`
       It also supports urls where ids are passed as a query param, such as `/comments?id=1`
      but not those where there is more than 1 query param such as `/comments?id=2&name=David`
      Currently only the query param of `id` is supported. If you need to support others, please
      override this or the `_stripIDFromURL` method.
       It does not group records that have differing base urls, such as for example: `/posts/1/comments/2`
      and `/posts/2/comments/3`

      Takes an ajax response, and returns the json payload or an error.
       By default this hook just returns the json payload passed to it.
      You might want to override it in two cases:
       1. Your API might return useful results in the response headers.
      Response headers are passed in as the second argument.
       2. Your API might return errors as successful responses with status code
      200 and an Errors text or object. You can return a `DS.InvalidError` or a
      `DS.AdapterError` (or a sub class) from this hook and it will automatically
      reject the promise and put your record into the invalid or error state.
       Returning a `DS.InvalidError` from this method will cause the
      record to transition into the `invalid` state and make the
      `errors` object available on the record. When returning an
      `DS.InvalidError` the store will attempt to normalize the error data
      returned from the server using the serializer's `extractErrors`
      method.

  /**
    `DS.attr` defines an attribute on a [DS.Model](/api/data/classes/DS.Model.html).
    By default, attributes are passed through as-is, however you can specify an
    optional type to have the value automatically transformed.
    Ember Data ships with four basic transform types: `string`, `number`,
    `boolean` and `date`. You can define your own transforms by subclassing
    [DS.Transform](/api/data/classes/DS.Transform.html).
  
    Note that you cannot use `attr` to define an attribute of `id`.
  
    `DS.attr` takes an optional hash as a second parameter, currently
    supported options are:
  
    - `defaultValue`: Pass a string or a function to be called to set the attribute
                      to a default value if none is supplied.
  
    Example
  
    ```app/models/user.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      username: DS.attr('string'),
      email: DS.attr('string'),
      verified: DS.attr('boolean', { defaultValue: false })
    });
    ```
  
    Default value can also be a function. This is useful it you want to return
    a new object for each attribute.
  
    ```app/models/user.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      username: attr('string'),
      email: attr('string'),
      settings: attr({defaultValue: function() {
        return {};
      }})
    });
    ```
  
    The `options` hash is passed as second argument to a transforms'
    `serialize` and `deserialize` method. This allows to configure a
    transformation and adapt the corresponding value, based on the config:
  
    ```app/models/post.js
    export default DS.Model.extend({
      text: DS.attr('text', {
        uppercase: true
      })
    });
    ```
  
    ```app/transforms/text.js
    export default DS.Transform.extend({
      serialize: function(value, options) {
        if (options.uppercase) {
          return value.toUpperCase();
        }
  
        return value;
      },
  
      deserialize: function(value) {
        return value;
      }
    })
    ```
  
    @namespace
    @method attr
    @for DS
    @param {String} type the attribute type
    @param {Object} options a hash of options
    @return {Attribute}

    If an Ember.js developer defines a subclass of DS.Store on their application,

    this code will automatically instantiate it and make it available on the
    router.
  
    Additionally, after an application's controllers have been injected, they will
    each have the store made available to them.

    App.PostsController = Ember.Controller.extend({

    instantiated, and the instance of `App.PostsController` will have its `store`
    property set to that instance.
  
    Note that this code will only be run if the `ember-application` package is
    loaded. If Ember Data is being used in an environment other than a
    typical application (e.g., node.js where only `ember-runtime` is available),

  /**
    ## Using Embedded Records
  
    `DS.EmbeddedRecordsMixin` supports serializing embedded records.
  
    To set up embedded records, include the mixin when extending a serializer,
    then define and configure embedded (model) relationships.
  
    Below is an example of a per-type serializer (`post` type).
  
    ```app/serializers/post.js
    import DS from 'ember-data';
  
    export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
      attrs: {
        author: { embedded: 'always' },
        comments: { serialize: 'ids' }
      }
    });
    ```
    Note that this use of `{ embedded: 'always' }` is unrelated to
    the `{ embedded: 'always' }` that is defined as an option on `DS.attr` as part of
    defining a model while working with the `ActiveModelSerializer`.  Nevertheless,
    using `{ embedded: 'always' }` as an option to `DS.attr` is not a valid way to setup
    embedded records.
  
    The `attrs` option for a resource `{ embedded: 'always' }` is shorthand for:
  
    ```js
    {
      serialize: 'records',
      deserialize: 'records'
    }
    ```
  
    ### Configuring Attrs
  
    A resource's `attrs` option may be set to use `ids`, `records` or false for the
    `serialize`  and `deserialize` settings.
  
    The `attrs` property can be set on the `ApplicationSerializer` or a per-type
    serializer.
  
    In the case where embedded JSON is expected while extracting a payload (reading)
    the setting is `deserialize: 'records'`, there is no need to use `ids` when
    extracting as that is the default behavior without this mixin if you are using
    the vanilla `EmbeddedRecordsMixin`. Likewise, to embed JSON in the payload while
    serializing `serialize: 'records'` is the setting to use. There is an option of
    not embedding JSON in the serialized payload by using `serialize: 'ids'`. If you
    do not want the relationship sent at all, you can use `serialize: false`.
  
  
    ### EmbeddedRecordsMixin defaults
    If you do not overwrite `attrs` for a specific relationship, the `EmbeddedRecordsMixin`
    will behave in the following way:

    HasMany:   `{ serialize: false, deserialize: 'ids' }`
  
    ### Model Relationships
  
    Embedded records must have a model defined to be extracted and serialized. Note that
    when defining any relationships on your model such as `belongsTo` and `hasMany`, you
    should not both specify `async: true` and also indicate through the serializer's
    `attrs` attribute that the related model should be embedded for deserialization.
    If a model is declared embedded for deserialization (`embedded: 'always'` or `deserialize: 'records'`),
    then do not use `async: true`.
  
    To successfully extract and serialize embedded records the model relationships
    must be setup correcty. See the
    [defining relationships](/guides/models/defining-models/#toc_defining-relationships)
    section of the **Defining Models** guide page.
  
    Records without an `id` property are not considered embedded records, model
    instances must have an `id` property to be used with Ember Data.
  
    ### Example JSON payloads, Models and Serializers
  
    **When customizing a serializer it is important to grok what the customizations
    are. Please read the docs for the methods this mixin provides, in case you need
    to modify it to fit your specific needs.**
  
    For example review the docs for each method of this mixin:
    * [normalize](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_normalize)
    * [serializeBelongsTo](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeBelongsTo)
    * [serializeHasMany](/api/data/classes/DS.EmbeddedRecordsMixin.html#method_serializeHasMany)

      Serialize `belongsTo` relationship when it is configured as an embedded object.

        post:     DS.belongsTo('post')
      });
      ```
       Use a custom (type) serializer for the post model to configure embedded author
       ```app/serializers/post.js
      import DS from 'ember-data';

        body:     DS.attr('string'),
        post:     DS.belongsTo('post')
      });
      ```
       Use a custom (type) serializer for the post model to configure embedded comments
       ```app/serializers/post.js
      import DS from 'ember-data;
       export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
        attrs: {
          comments: { embedded: 'always' }
        }
      })
      ```
       A payload with an attribute configured for embedded records can serialize
      the records together under the root attribute's payload:
       ```js
      {
        "post": {
          "id": "1"
          "title": "Rails is omakase",
          "body": "I want this for my ORM, I want that for my template language..."
          "comments": [{
            "id": "1",
            "body": "Rails is unagi"
          }, {
            "id": "2",
            "body": "Omakase O_o"
          }]
        }
      }
      ```
       The attrs options object can use more specific instruction for extracting and
      serializing. When serializing, an option to embed `ids`, `ids-and-types` or `records` can be set.
      When extracting the only option is `records`.
       So `{ embedded: 'always' }` is shorthand for:
      `{ serialize: 'records', deserialize: 'records' }`
       To embed the `ids` for a related object (using a hasMany relationship):
       ```app/serializers/post.js
      import DS from 'ember-data;
       export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
        attrs: {
          comments: { serialize: 'ids', deserialize: 'records' }
        }
      })
      ```
       ```js
      {
        "post": {
          "id": "1"
          "title": "Rails is omakase",
          "body": "I want this for my ORM, I want that for my template language..."
          "comments": ["1", "2"]
        }
      }
      ```
       To embed the relationship as a collection of objects with `id` and `type` keys, set
      `ids-and-types` for the related object.
       This is particularly useful for polymorphic relationships where records don't share
      the same table and the `id` is not enough information.
       By example having a user that has many pets:
       ```js
      User = DS.Model.extend({
        name:    DS.attr('string'),
        pets: DS.hasMany('pet', { polymorphic: true })
      });
       Pet = DS.Model.extend({
        name: DS.attr('string'),
      });
       Cat = Pet.extend({
        // ...
      });
       Parrot = Pet.extend({
        // ...
      });
      ```
       ```app/serializers/user.js
      import DS from 'ember-data;
       export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
        attrs: {
          pets: { serialize: 'ids-and-types', deserialize: 'records' }
        }
      });
      ```

  /**
    Ember Data 2.0 Serializer:
  
    In Ember Data a Serializer is used to serialize and deserialize
    records when they are transferred in and out of an external source.
    This process involves normalizing property names, transforming
    attribute values and serializing relationships.
  
    `JSONAPISerializer` supports the http://jsonapi.org/ spec and is the
    serializer recommended by Ember Data.
  
    This serializer normalizes a JSON API payload that looks like:
  
    ```js
  
      // models/player.js
      import DS from "ember-data";
  
      export default DS.Model.extend({
        name: DS.attr(),
        skill: DS.attr(),
        gamesPlayed: DS.attr(),
        club: DS.belongsTo('club')
      });
  
      // models/club.js
      import DS from "ember-data";
  
      export default DS.Model.extend({
        name: DS.attr(),
        location: DS.attr(),
        players: DS.hasMany('player')
      });
    ```
  
    ```js
  
      {

    ### Customizing meta
  
    Since a JSON API Document can have meta defined in multiple locations you can
    use the specific serializer hooks if you need to customize the meta.
  
    One scenario would be to camelCase the meta keys of your payload. The example
    below shows how this could be done using `normalizeArrayResponse` and
    `extractRelationship`.
  
    ```app/serializers/application.js
    export default JSONAPISerializer.extend({
  
      normalizeArrayResponse(store, primaryModelClass, payload, id, requestType) {
        let normalizedDocument = this._super(...arguments);
  
        // Customize document meta
        normalizedDocument.meta = camelCaseKeys(normalizedDocument.meta);
  
        return normalizedDocument;
      },
  
      extractRelationship(relationshipHash) {
        let normalizedRelationship = this._super(...arguments);
  
        // Customize relationship meta
        normalizedRelationship.meta = camelCaseKeys(normalizedRelationship.meta);
  
        return normalizedRelationship;
      }
  
    });
    ```

  /**
    Ember Data 2.0 Serializer:
  
    In Ember Data a Serializer is used to serialize and deserialize
    records when they are transferred in and out of an external source.
    This process involves normalizing property names, transforming
    attribute values and serializing relationships.
  
    By default, Ember Data uses and recommends the `JSONAPISerializer`.
  
    `JSONSerializer` is useful for simpler or legacy backends that may
    not support the http://jsonapi.org/ spec.
  
    For example, given the following `User` model and JSON payload:
  
    ```app/models/user.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      friends: DS.hasMany('user'),
      house: DS.belongsTo('location'),
  
      name: DS.attr('string')
    });
    ```
  
    ```js
    {
      id: 1,
      name: 'Sebastian',
      friends: [3, 4],
      links: {
        house: '/houses/lefkada'
      }
    }
    ```
  
    `JSONSerializer` will normalize the JSON payload to the JSON API format that the
    Ember Data store expects.
  
    You can customize how JSONSerializer processes its payload by passing options in
    the `attrs` hash or by subclassing the `JSONSerializer` and overriding hooks:
  
      - To customize how a single record is normalized, use the `normalize` hook.
      - To customize how `JSONSerializer` normalizes the whole server response, use the
        `normalizeResponse` hook.
      - To customize how `JSONSerializer` normalizes a specific response from the server,
        use one of the many specific `normalizeResponse` hooks.
      - To customize how `JSONSerializer` normalizes your id, attributes or relationships,
        use the `extractId`, `extractAttributes` and `extractRelationships` hooks.
  
    The `JSONSerializer` normalization process follows these steps:
  
      - `normalizeResponse` - entry method to the serializer.
      - `normalizeCreateRecordResponse` - a `normalizeResponse` for a specific operation is called.
      - `normalizeSingleResponse`|`normalizeArrayResponse` - for methods like `createRecord` we expect
        a single record back, while for methods like `findAll` we expect multiple methods back.
      - `normalize` - `normalizeArray` iterates and calls `normalize` for each of its records while `normalizeSingle`
        calls it once. This is the method you most likely want to subclass.
      - `extractId` | `extractAttributes` | `extractRelationships` - `normalize` delegates to these methods to
        turn the record payload into the JSON API format.

    /**
      The `primaryKey` is used when serializing and deserializing
      data. Ember Data always uses the `id` property to store the id of
      the record. The external source may not always follow this
      convention. In these cases it is useful to override the
      `primaryKey` property to match the `primaryKey` of your external
      store.
       Example
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        primaryKey: '_id'
      });
      ```
       @property primaryKey
      @type {String}
      @default 'id'
    */
    primaryKey: 'id',

    /**
      The `attrs` object can be used to declare a simple mapping between
      property names on `DS.Model` records and payload keys in the
      serialized JSON object representing the record. An object with the
      property `key` can also be used to designate the attribute's key on
      the response payload.
       Example
       ```app/models/person.js
      import DS from 'ember-data';
       export default DS.Model.extend({
        firstName: DS.attr('string'),
        lastName: DS.attr('string'),
        occupation: DS.attr('string'),
        admin: DS.attr('boolean')
      });
      ```
       ```app/serializers/person.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        attrs: {
          admin: 'is_admin',
          occupation: { key: 'career' }
        }
      });
      ```
       You can also remove attributes by setting the `serialize` key to
      `false` in your mapping object.
       Example
       ```app/serializers/person.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        attrs: {
          admin: { serialize: false },
          occupation: { key: 'career' }
        }
      });
      ```
       When serialized:
       ```javascript
      {
        "firstName": "Harry",
        "lastName": "Houdini",
        "career": "magician"
      }
      ```
       Note that the `admin` is now not included in the payload.

    // SERIALIZE
    /**
      Called when a record is saved in order to convert the
      record into JSON.
       By default, it creates a JSON object with a key for
      each attribute and belongsTo relationship.
       For example, consider this model:
       ```app/models/comment.js
      import DS from 'ember-data';
       export default DS.Model.extend({
        title: DS.attr(),
        body: DS.attr(),
         author: DS.belongsTo('user')
      });
      ```
       The default serialization would create a JSON object like:
       ```javascript
      {
        "title": "Rails is unagi",
        "body": "Rails? Omakase? O_O",
        "author": 12
      }
      ```
       By default, attributes are passed through as-is, unless
      you specified an attribute type (`DS.attr('date')`). If
      you specify a transform, the JavaScript value will be
      serialized when inserted into the JSON hash.
       By default, belongs-to relationships are converted into
      IDs when inserted into the JSON hash.
       ## IDs
       `serialize` takes an options hash with a single option:
      `includeId`. If this option is `true`, `serialize` will,
      by default include the ID in the JSON object it builds.
       The adapter passes in `includeId: true` when serializing
      a record for `createRecord`, but not for `updateRecord`.
       ## Customization
       Your server may expect a different JSON format than the
      built-in serialization format.
       In that case, you can implement `serialize` yourself and
      return a JSON hash of your choosing.
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        serialize: function(snapshot, options) {
          var json = {
            POST_TTL: snapshot.attr('title'),
            POST_BDY: snapshot.attr('body'),
            POST_CMS: snapshot.hasMany('comments', { ids: true })
          }
           if (options.includeId) {
            json.POST_ID_ = snapshot.id;
          }
           return json;
        }
      });
      ```
       ## Customizing an App-Wide Serializer
       If you want to define a serializer for your entire
      application, you'll probably want to use `eachAttribute`
      and `eachRelationship` on the record.
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        serialize: function(snapshot, options) {
          var json = {};
           snapshot.eachAttribute(function(name) {
            json[serverAttributeName(name)] = snapshot.attr(name);
          })
           snapshot.eachRelationship(function(name, relationship) {
            if (relationship.kind === 'hasMany') {
              json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
            }
          });
           if (options.includeId) {
            json.ID_ = snapshot.id;
          }
           return json;
        }
      });
       function serverAttributeName(attribute) {
        return attribute.underscore().toUpperCase();
      }
       function serverHasManyName(name) {
        return serverAttributeName(name.singularize()) + "_IDS";
      }
      ```
       This serializer will generate JSON that looks like this:
       ```javascript
      {
        "TITLE": "Rails is omakase",
        "BODY": "Yep. Omakase.",
        "COMMENT_IDS": [ 1, 2, 3 ]
      }
      ```
       ## Tweaking the Default JSON
       If you just want to do some small tweaks on the default JSON,
      you can call super first and make the tweaks on the returned
      JSON.
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        serialize: function(snapshot, options) {
          var json = this._super.apply(this, arguments);
           json.subject = json.title;
          delete json.title;
           return json;
        }
      });
      ```
       @method serialize
      @param {DS.Snapshot} snapshot
      @param {Object} options
      @return {Object} json
    */
    serialize: function (snapshot, options) {
      var _this5 = this;

      var json = {};

      if (options && options.includeId) {
        if (true) {
          this.serializeId(snapshot, json, get(this, 'primaryKey'));
        } else {
          var id = snapshot.id;
          if (id) {
            json[get(this, 'primaryKey')] = id;
          }
        }
      }

      snapshot.eachAttribute(function (key, attribute) {
        _this5.serializeAttribute(snapshot, json, key, attribute);
      });

      snapshot.eachRelationship(function (key, relationship) {
        if (relationship.kind === 'belongsTo') {
          _this5.serializeBelongsTo(snapshot, json, relationship);
        } else if (relationship.kind === 'hasMany') {
          _this5.serializeHasMany(snapshot, json, relationship);
        }
      });

      return json;
    },

      `extractErrors` is used to extract model errors when a call
      to `DS.Model#save` fails with an `InvalidError`. By default
      Ember Data expects error information to be located on the `errors`
      property of the payload object.
       This serializer expects this `errors` object to be an Array similar
      to the following, compliant with the JSON-API specification:
       ```js
      {
        "errors": [
          {
            "detail": "This username is already taken!",
            "source": {
              "pointer": "data/attributes/username"
            }
          }, {
            "detail": "Doesn't look like a valid email.",
            "source": {
              "pointer": "data/attributes/email"
            }
          }
        ]
      }
      ```
       The key `detail` provides a textual description of the problem.
      Alternatively, the key `title` can be used for the same purpose.
       The nested keys `source.pointer` detail which specific element
      of the request data was invalid.
       Note that JSON-API also allows for object-level errors to be placed
      in an object with pointer `data`, signifying that the problem
      cannot be traced to a specific attribute:
       ```javascript
      {
        "errors": [
          {
            "detail": "Some generic non property error message",
            "source": {
              "pointer": "data"
            }
          }
        ]
      }
      ```
       When turn into a `DS.Errors` object, you can read these errors
      through the property `base`:
       ```handlebars
      {{#each model.errors.base as |error|}}
        <div class="error">
          {{error.message}}
        </div>
      {{/each}}
      ```
       Example of alternative implementation, overriding the default
      behavior to deal with a different format of errors:
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.JSONSerializer.extend({
        extractErrors: function(store, typeClass, payload, id) {

            payload = payload._problems;

          }
          return payload;
        }

  /**
    Normally, applications will use the `RESTSerializer` by implementing
    the `normalize` method.
  
    This allows you to do whatever kind of munging you need, and is
    especially useful if your server is inconsistent and you need to
    do munging differently for many different kinds of responses.
  
    See the `normalize` documentation for more information.
  
    ## Across the Board Normalization
  
    There are also a number of hooks that you might find useful to define
    across-the-board rules for your payload. These rules will be useful
    if your server is consistent, or if you're building an adapter for
    an infrastructure service, like Firebase, and want to encode service
    conventions.
  
    For example, if all of your keys are underscored and all-caps, but
    otherwise consistent with the names you use in your models, you
    can implement across-the-board rules for how to convert an attribute
    name in your model to a key in your JSON.
  
    ```app/serializers/application.js
    import DS from 'ember-data';
  
    export default DS.RESTSerializer.extend({
      keyForAttribute: function(attr, method) {
        return Ember.String.underscore(attr).toUpperCase();
      }
    });
    ```
  
    You can also implement `keyForRelationship`, which takes the name
    of the relationship as the first parameter, the kind of
    relationship (`hasMany` or `belongsTo`) as the second parameter, and
    the method (`serialize` or `deserialize`) as the third parameter.
  
    @class RESTSerializer
    @namespace DS
    @extends DS.JSONSerializer

    /**
     `keyForPolymorphicType` can be used to define a custom key when

       ```app/serializers/post.js

        }
      });

    /**
      Normalizes a part of the JSON payload returned by
      the server. You should override this method, munge the hash
      and call super if you have generic normalization to do.
       It takes the type of the record that is being normalized
      (as a DS.Model class), the property where the hash was
      originally found, and the hash to normalize.
       For example, if you have a payload that looks like this:
       ```js
      {
        "post": {
          "id": 1,
          "title": "Rails is omakase",
          "comments": [ 1, 2 ]
        },
        "comments": [{
          "id": 1,
          "body": "FIRST"
        }, {
          "id": 2,
          "body": "Rails is unagi"
        }]
      }
      ```
       The `normalize` method will be called three times:
       * With `App.Post`, `"posts"` and `{ id: 1, title: "Rails is omakase", ... }`
      * With `App.Comment`, `"comments"` and `{ id: 1, body: "FIRST" }`
      * With `App.Comment`, `"comments"` and `{ id: 2, body: "Rails is unagi" }`
       You can use this method, for example, to normalize underscored keys to camelized
      or other general-purpose normalizations. You will only need to implement
      `normalize` and manipulate the payload as desired.
       For example, if the `IDs` under `"comments"` are provided as `_id` instead of
      `id`, you can specify how to normalize just the comments:
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        normalize(model, hash, prop) {
          if (prop === 'comments') {
            hash.id = hash._id;
            delete hash._id;
          }
           return this._super(...arguments);
        }
      });
      ```
       On each call to the `normalize` method, the third parameter (`prop`) is always
      one of the keys that were in the original payload or in the result of another
      normalization as `normalizeResponse`.
       @method normalize

    /**
      This method is used to convert each JSON root key in the payload
      into a modelName that it can use to look up the appropriate model for
      that part of the payload.
       For example, your server may send a model name that does not correspond with
      the name of the model in your app. Let's take a look at an example model,
      and an example payload:
       ```app/models/post.js
      import DS from 'ember-data';
       export default DS.Model.extend({
      });
      ```
       ```javascript
        {
          "blog/post": {
            "id": "1
          }
        }
      ```
       Ember Data is going to normalize the payload's root key for the modelName. As a result,
      it will try to look up the "blog/post" model. Since we don't have a model called "blog/post"
      (or a file called app/models/blog/post.js in ember-cli), Ember Data will throw an error
      because it cannot find the "blog/post" model.
       Since we want to remove this namespace, we can define a serializer for the application that will
      remove "blog/" from the payload key whenver it's encountered by Ember Data:
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        modelNameFromPayloadKey: function(payloadKey) {
          if (payloadKey === 'blog/post') {
            return this._super(payloadKey.replace('blog/', ''));
          } else {
           return this._super(payloadKey);
          }
        }
      });
      ```
       After refreshing, Ember Data will appropriately look up the "post" model.
       By default the modelName for a model is its
      name in dasherized form. This means that a payload key like "blogPost" would be
      normalized to "blog-post" when Ember Data looks up the model. Usually, Ember Data
      can use the correct inflection to do this for you. Most of the time, you won't
      need to override `modelNameFromPayloadKey` for this purpose.
       @method modelNameFromPayloadKey
      @param {String} key
      @return {String} the model's modelName
    */
    modelNameFromPayloadKey: function (key) {
      return (0, _emberInflector.singularize)((0, _emberDataPrivateSystemNormalizeModelName.default)(key));
    },

    // SERIALIZE

    /**
      Called when a record is saved in order to convert the
      record into JSON.
       By default, it creates a JSON object with a key for
      each attribute and belongsTo relationship.
       For example, consider this model:
       ```app/models/comment.js
      import DS from 'ember-data';
       export default DS.Model.extend({
        title: DS.attr(),
        body: DS.attr(),
         author: DS.belongsTo('user')
      });
      ```
       The default serialization would create a JSON object like:
       ```js
      {
        "title": "Rails is unagi",
        "body": "Rails? Omakase? O_O",
        "author": 12
      }
      ```
       By default, attributes are passed through as-is, unless
      you specified an attribute type (`DS.attr('date')`). If
      you specify a transform, the JavaScript value will be
      serialized when inserted into the JSON hash.
       By default, belongs-to relationships are converted into
      IDs when inserted into the JSON hash.
       ## IDs
       `serialize` takes an options hash with a single option:
      `includeId`. If this option is `true`, `serialize` will,
      by default include the ID in the JSON object it builds.
       The adapter passes in `includeId: true` when serializing
      a record for `createRecord`, but not for `updateRecord`.
       ## Customization
       Your server may expect a different JSON format than the
      built-in serialization format.
       In that case, you can implement `serialize` yourself and
      return a JSON hash of your choosing.
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        serialize: function(snapshot, options) {
          var json = {
            POST_TTL: snapshot.attr('title'),
            POST_BDY: snapshot.attr('body'),
            POST_CMS: snapshot.hasMany('comments', { ids: true })
          }
           if (options.includeId) {
            json.POST_ID_ = snapshot.id;
          }
           return json;
        }
      });
      ```
       ## Customizing an App-Wide Serializer
       If you want to define a serializer for your entire
      application, you'll probably want to use `eachAttribute`
      and `eachRelationship` on the record.
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        serialize: function(snapshot, options) {
          var json = {};
           snapshot.eachAttribute(function(name) {
            json[serverAttributeName(name)] = snapshot.attr(name);
          })
           snapshot.eachRelationship(function(name, relationship) {
            if (relationship.kind === 'hasMany') {
              json[serverHasManyName(name)] = snapshot.hasMany(name, { ids: true });
            }
          });
           if (options.includeId) {
            json.ID_ = snapshot.id;
          }
           return json;
        }
      });
       function serverAttributeName(attribute) {
        return attribute.underscore().toUpperCase();
      }
       function serverHasManyName(name) {
        return serverAttributeName(name.singularize()) + "_IDS";
      }
      ```
       This serializer will generate JSON that looks like this:
       ```js
      {
        "TITLE": "Rails is omakase",
        "BODY": "Yep. Omakase.",
        "COMMENT_IDS": [ 1, 2, 3 ]
      }
      ```
       ## Tweaking the Default JSON
       If you just want to do some small tweaks on the default JSON,
      you can call super first and make the tweaks on the returned
      JSON.
       ```app/serializers/post.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        serialize: function(snapshot, options) {
          var json = this._super(snapshot, options);
           json.subject = json.title;
          delete json.title;
           return json;
        }
      });
      ```
       @method serialize
      @param {DS.Snapshot} snapshot
      @param {Object} options
      @return {Object} json
    */
    serialize: function (snapshot, options) {
      return this._super.apply(this, arguments);
    },

    /**
      You can use this method to customize the root keys serialized into the JSON.
      The hash property should be modified by reference (possibly using something like _.extend)
      By default the REST Serializer sends the modelName of a model, which is a camelized
      version of the name.
       For example, your server may expect underscored root objects.
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        serializeIntoHash: function(data, type, record, options) {
          var root = Ember.String.decamelize(type.modelName);
          data[root] = this.serialize(record, options);
        }
      });
      ```
       @method serializeIntoHash
      @param {Object} hash
      @param {DS.Model} typeClass
      @param {DS.Snapshot} snapshot
      @param {Object} options
    */
    serializeIntoHash: function (hash, typeClass, snapshot, options) {
      var normalizedRootKey = this.payloadKeyFromModelName(typeClass.modelName);
      hash[normalizedRootKey] = this.serialize(snapshot, options);
    },

    /**
      You can use `payloadKeyFromModelName` to override the root key for an outgoing
      request. By default, the RESTSerializer returns a camelized version of the
      model's name.
       For a model called TacoParty, its `modelName` would be the string `taco-party`. The RESTSerializer
      will send it to the server with `tacoParty` as the root key in the JSON payload:
       ```js
      {
        "tacoParty": {
          "id": "1",
          "location": "Matthew Beale's House"
        }
      }
      ```
       For example, your server may expect dasherized root objects:
       ```app/serializers/application.js
      import DS from 'ember-data';
       export default DS.RESTSerializer.extend({
        payloadKeyFromModelName: function(modelName) {
          return Ember.String.dasherize(modelName);
        }
      });
      ```
       Given a `TacoParty` model, calling `save` on it would produce an outgoing
      request like:
       ```js
      {
        "taco-party": {
          "id": "1",
          "location": "Matthew Beale's House"
        }
      }
      ```
       @method payloadKeyFromModelName
      @param {String} modelName
      @return {String}

    payloadKeyFromModelName: function (modelName) {
      return camelize(modelName);
    },

    /**

        payload for the `post` model, which has a polymorphic `user` relationship:
         ```javascript
        // GET /api/posts/1

          }
        }
        ```
         By overwriting `modelNameFromPayloadType` you can specify that the

  /**
    The `DS.Transform` class is used to serialize and deserialize model
    attributes when they are saved or loaded from an
    adapter. Subclassing `DS.Transform` is useful for creating custom
    attributes. All subclasses of `DS.Transform` must implement a
    `serialize` and a `deserialize` method.
  
    Example
  
    ```app/transforms/temperature.js
    import DS from 'ember-data';
  
    // Converts centigrade in the JSON to fahrenheit in the app
    export default DS.Transform.extend({
      deserialize: function(serialized, options) {
        return (serialized *  1.8) + 32;
      },
      serialize: function(deserialized, options) {
        return (deserialized - 32) / 1.8;
      }
    });
    ```
  
    The options passed into the `DS.attr` function when the attribute is
    declared on the model is also available in the transform.
  
    ```app/models/post.js
    export default DS.Model.extend({
      title: DS.attr('string'),
      markdown: DS.attr('markdown', {
        markdown: {
          gfm: false,
          sanitize: true
        }
      })
    });
    ```
  
    ```app/transforms/markdown.js
    export default DS.Transform.extend({
      serialize: function (deserialized, options) {
        return deserialized.raw;
      },
  
      deserialize: function (serialized, options) {
        var markdownOptions = options.markdown || {};
  
        return marked(serialized, markdownOptions);
      }
    });
    ```
  
    Usage
  
    ```app/models/requirement.js
    import DS from 'ember-data';
  
    export default DS.Model.extend({
      name: DS.attr('string'),
      temperature: DS.attr('temperature')

    Inflector.Ember provides a mechanism for supplying inflection rules for your
    application. Ember includes a default set of inflection rules, and provides an
    API for providing additional rules.
  
    Examples:
  
    Creating an inflector with no rules.
  
    ```js
    var inflector = new Ember.Inflector();
    ```
  
    Creating an inflector with the default ember ruleset.
  
    ```js
    var inflector = new Ember.Inflector(Ember.Inflector.defaultRules);
  
    inflector.pluralize('cow'); //=> 'kine'
    inflector.singularize('kine'); //=> 'cow'
    ```
  
    Creating an inflector and adding rules later.
  
    ```javascript
    var inflector = Ember.Inflector.inflector;
  
    inflector.pluralize('advice'); // => 'advices'
    inflector.uncountable('advice');
    inflector.pluralize('advice'); // => 'advice'
  
    inflector.pluralize('formula'); // => 'formulas'
    inflector.irregular('formula', 'formulae');
    inflector.pluralize('formula'); // => 'formulae'
  
    // you would not need to add these as they are the default rules
    inflector.plural(/$/, 's');
    inflector.singular(/s$/i, '');
    ```
  
    Creating an inflector with a nondefault ruleset.
  
    ```javascript
    var rules = {
      plurals:  [ /$/, 's' ],
      singular: [ /\s$/, '' ],
