/**
  In Ember Data a Serializer is used to serialize and deserialize
  records when they are transfered in and out of an external source.
  This process involves normalizing property names, transforming
  attribute values and serializeing relationships.

  For maximum performance Ember Data recomends you use the
  [RESTSerializer](DS.RESTSerializer.html) or one of its subclasses.

  `JSONSerializer` is useful for simpler or legacy backends that may
  not support the http://jsonapi.org/ spec.

  @class JSONSerializer
  @namespace DS
*/
DS.JSONSerializer = Ember.Object.extend({
  /**
    The primaryKey is used when serializing and deserializing
    data. Ember Data always uses the `id` propery to store the id of
    the record. The external source may not always follow this
    convention. In these cases it is usesful to override the
    primaryKey property to match the primaryKey of your external
    store.

    Example

    ```javascript
    App.ApplicationSerializer = DS.JSONSerializer.extend({
      primaryKey: '_id'
    });
    ```

    @property primaryKey
    @type {String}

   serializer's `normalize` method.

   @method applyTransforms

   @param {Object} data The data to transform
   @return {Object} data The transformed data object

  applyTransforms: function(type, data) {
    type.eachTransformedAttribute(function(key, type) {
      var transform = this.transformFor(type);

    return data;
  },

  /**
    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.

    You can use this method, for example, to normalize underscored keys to camelized
    or other general-purpose normalizations.

    Example

    ```javascript
    App.ApplicationSerializer = DS.JSONSerializer.extend({
      normalize: function(type, hash) {
        var normalizedHash = {};
        var fields = Ember.get(type, 'fields');
        fields.forEach(function(field) {
          var normalizedProp = Ember.String.camelize(field);
          normalizedHash[normalizedProp] = hash[field];
        });
        return this._super.apply(this, arguments);
      }
    });
    ```

    @method normalize
    @param {subclass of DS.Model} type
    @param {Object} hash
    @return {Object}
  */
  normalize: function(type, hash) {
    if (!hash) { return hash; }

    this.applyTransforms(type, hash);
    return hash;
  },

  // 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:

    ```javascript
    App.Comment = 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.

    ```javascript
    App.PostSerializer = DS.JSONSerializer.extend({
      serialize: function(post, options) {
        var json = {
          POST_TTL: post.get('title'),
          POST_BDY: post.get('body'),
          POST_CMS: post.get('comments').mapProperty('id')
        }

        if (options.includeId) {
          json.POST_ID_ = post.get('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.

    ```javascript
    App.ApplicationSerializer = DS.JSONSerializer.extend({
      serialize: function(record, options) {
        var json = {};

        record.eachAttribute(function(name) {
          json[serverAttributeName(name)] = record.get(name);
        })

        record.eachRelationship(function(name, relationship) {
          if (relationship.kind === 'hasMany') {
            json[serverHasManyName(name)] = record.get(name).mapBy('id');
          }
        });

        if (options.includeId) {
          json.ID_ = record.get('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.

    ```javascript
    App.PostSerializer = DS.JSONSerializer.extend({
      serialize: function(record, options) {
        var json = this._super.apply(this, arguments);

        json.subject = json.title;
        delete json.title;

        return json;
      }
    });
    ```

    @method serialize
    @param {subclass of DS.Model} record
    @param {Object} options
    @return {Object} json
  */
  serialize: function(record, options) {
    var json = {};

    if (options && options.includeId) {
      var id = get(record, 'id');

      if (id) {
        json[get(this, 'primaryKey')] = get(record, 'id');
      }
    }

    record.eachAttribute(function(key, attribute) {
      this.serializeAttribute(record, json, key, attribute);
    }, this);

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

    return json;
  },

  /**
   `serializeAttribute` can be used to customize how `DS.attr`
   properties are serialized

   For example if you wanted to ensure all you attributes were always
   serialized as properties on an `attributes` object you could
   write:

   App.ApplicationSerializer = DS.JSONSerializer.extend({
     serializeAttribute: function(record, json, key, attributes) {
       json.attributes = json.attributes || {};

     }

    var value = get(record, key), type = attribute.type;

    if (type) {
      var transform = this.transformFor(type);
      value = transform.serialize(value);
    }

    // if provided, use the mapping provided by `attrs` in
    // the serializer
    key = attrs && attrs[key] || (this.keyForAttribute ? this.keyForAttribute(key) : key);

    json[key] = value;
  },

       json[key] = Ember.isNone(belongsTo) ? belongsTo : belongsTo.toJSON();
     }

      json[key] = belongsTo;

    }

    if (relationship.options.polymorphic) {
      this.serializePolymorphicType(record, json, relationship);

         return;
       } else {
         this._super.apply(this, arguments);
       }
     }
   });
   ```

// Implementors Note:

//   The variables in this file are consistently named according to the following
//   scheme:
//
//   * +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.
//   * +reference+ means a record reference object, which holds metadata about a
//     record, even if it has not yet been fully materialized.
//   * +type+ means a subclass of DS.Model.

// Used by the store to normalize IDs entering the store.  Despite the fact
// that developers may provide IDs as numbers (e.g., `store.find(Person, 1)`),
// it is important that internally we use strings, since IDs may be serialized
// and lose type information.  For example, Ember's router may put a record's
// ID into the URL, and if we later try to deserialize that URL and find the
// corresponding record, we will not know if it is a string or a number.

/**
  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:

  ```javascript
  MyApp.Store = 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.Model`'s `find()` method:

  ```javascript
  var person = App.Person.find(123);
  ```

  If your application has multiple `DS.Store` instances (an unusual case), you can
  specify which store should be used:

  ```javascript
  var person = store.find(App.Person, 123);
  ```

  In general, you should retrieve models using the methods on `DS.Model`; you should
  rarely need to interact with the store directly.

  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:

  ```javascript
   MyApp.store = DS.Store.create({
     adapter: 'MyApp.CustomAdapter'
   });
   ```

  You can learn more about writing a custom adapter by reading the `DS.Adapter`
  documentation.

    To find a record by ID, pass the `id` as the second parameter:

    The `find` method will always return a **promise** that will be resolved

  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. (These 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 we mean 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.

// 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.
// * isError: The adapter reported that it was unable to save
//   local changes to the backend. This may also result in the
//   record having its `isValid` property become false if the
//   adapter reported that server-side validations failed.
// * isNew: The record was created on the client and the adapter
//   did not yet report that it was successfully saved.
// * isValid: No client-side validations have failed and 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

/**
  `DS.attr` defines an attribute on a [DS.Model](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](DS.Transform.html).

  `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

  ```javascript
  var attr = DS.attr;

  App.User = DS.Model.extend({
    username: attr('string'),
    email: attr('string'),
    verified: attr('boolean', {defaultValue: false})
  });

  @namespace
  @method attr
  @for DS
  @param {String} type the attribute type
  @param {Object} options a hash of options
  @return {Attribute}

  `DS.belongsTo` is used to define One-To-One and One-To-Many

/**
  `DS.hasMany` is used to define One-To-Many and Many-To-Many
  relationships on a [DS.Model](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:

  ```javascript
  App.Post = DS.Model.extend({
    comments: DS.hasMany('comment')
  });

  App.Comment = DS.Model.extend({
    post: DS.belongsTo('post')
  });
  ```

  #### Many-To-Many
  To declare a many-to-many relationship between two models, use
  `DS.hasMany`:

  ```javascript
  App.Post = DS.Model.extend({
    tags: DS.hasMany('tag')
  });

  App.Tag = DS.Model.extend({
    posts: DS.hasMany('post')
  });
  ```

  #### 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:

  ```javascript
  var belongsTo = DS.belongsTo,
      hasMany = DS.hasMany;

  App.Comment = DS.Model.extend({
    onePost: belongsTo('post'),
    twoPost: belongsTo('post'),
    redPost: belongsTo('post'),
    bluePost: belongsTo('post')
  });

  App.Post = DS.Model.extend({
    comments: hasMany('comment', {
      inverse: 'redPost'
    })
  });
  ```

  You can also specify an inverse on a `belongsTo`, which works how
  you'd expect.

  @namespace
  @method hasMany
  @for DS
  @param {String or DS.Model} type the model type of the relationship
  @param {Object} options a hash of options
  @return {Ember.computed} relationship
*/
DS.hasMany = function(type, options) {
  if (typeof type === 'object') {
    options = type;
    type = undefined;
  }
  return hasRelationship(type, options);

/**
  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.

  ### Creating an Adapter

  First, create a new subclass of `DS.Adapter`:

  ```javascript
  App.MyAdapter = DS.Adapter.extend({
    // ...your code here
  });
  ```

  To tell your store which adapter to use, set its `adapter` property:

  ```javascript
  App.store = DS.Store.create({
    adapter: App.MyAdapter.create()
  });
  ```

  `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:

    * `find()`
    * `createRecord()`
    * `updateRecord()`
    * `deleteRecord()`

  To improve the network performance of your application, you can optimize
  your adapter by overriding these lower-level methods:

    * `findMany()`
    * `createRecords()`
    * `updateRecords()`
    * `deleteRecords()`
    * `commit()`

  For an example implementation, see `DS.RESTAdapter`, the
  included REST adapter.

  @class Adapter
  @namespace DS
  @extends Ember.Object
*/

DS.Adapter = Ember.Object.extend({

  /**
    The `find()` method is invoked when the store is asked for a record that
    has not previously been loaded. In response to `find()` being called, you
    should query your persistence layer for a record with the given ID. Once
    found, you can asynchronously call the store's `push()` method to push
    the record into the store.

    Here is an example `find` implementation:

    ```javascript
    find: function(store, type, id) {
      var url = type.url;
      url = url.fmt(id);

      jQuery.getJSON(url, function(data) {
          // data is a hash of key/value pairs. If your server returns a
          // root, simply do something like:
          // store.push(type, id, data.person)
          store.push(type, id, data);
      });
    }
    ```

    Most traditional REST-like HTTP APIs will not use this method. Instead, the ID
    of the record will be set by the server, and your adapter will update the store
    with the new ID when it calls `didCreateRecord()`. Only implement this method if
    you intend to generate record IDs on the client-side.

    The `generateIdForRecord()` method will be invoked with the requesting store as
    the first parameter and the newly created record as the second parameter:

/**
  Normally, applications will use the `RESTSerializer` by implementing
  the `normalize` method and individual normalizations under
  `normalizeHash`.

  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 defined
  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 Parse, 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.

  ```js
  App.ApplicationSerializer = DS.RESTSerializer.extend({
    keyForAttribute: function(attr) {
      return Ember.String.underscore(attr).toUpperCase();
    }
  });
  ```

  You can also implement `keyForRelationship`, which takes the name
  of the relationship as the first parameter, and the kind of
  relationship (`hasMany` or `belongsTo`) as the second parameter.

  @class RESTSerializer
  @namespace DS
  @extends DS.JSONSerializer
*/
DS.RESTSerializer = DS.JSONSerializer.extend({
  /**
    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.

    If you want to do normalizations specific to some part of the payload, you
    can specify those under `normalizeHash`.

    For example, if the `IDs` under `"comments"` are provided as `_id` instead of
    `id`, you can specify how to normalize just the comments:

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      normalizeHash: {
        comments: function(hash) {
          hash.id = hash._id;
          delete hash._id;
          return hash;
        }
      }
    });
    ```

    The key under `normalizeHash` is just the original key that was in the original
    payload.

    a single record, such as in response to a `find` or `save`.

    It is your opportunity to clean up the server's response into the normalized
    form expected by Ember Data.

    If you want, you can just restructure the top-level of your payload, and
    do more fine-grained normalization in the `normalize` method.

    For example, if you have a payload like this in response to a request for
    post 1:

    ```js
    {
      "id": 1,
      "title": "Rails is omakase",

      "_embedded": {
        "comment": [{
          "_id": 1,
          "comment_title": "FIRST"
        }, {
          "_id": 2,
          "comment_title": "Rails is unagi"
        }]
      }
    }
    ```

    You could implement a serializer that looks like this to get your payload
    into shape:

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      // First, restructure the top-level so it's organized by type
      extractSingle: function(store, type, payload, id, requestType) {
        var comments = payload._embedded.comment;
        delete payload._embedded;

        payload = { comments: comments, post: payload };
        return this._super(store, type, payload, id, requestType);
      },

      normalizeHash: {
        // Next, normalize individual comments, which (after `extract`)
        // are now located under `comments`
        comments: function(hash) {
          hash.id = hash._id;
          hash.title = hash.comment_title;
          delete hash._id;
          delete hash.comment_title;
          return hash;
        }
      }
    })
    ```

    When you call super from your own implementation of `extractSingle`, the
    built-in implementation will find the primary record in your normalized
    payload and push the remaining records into the store.

    The primary record is the single hash found under `post` or the first
    element of the `posts` array.

    The primary record has special meaning when the record is being created
    for the first time or updated (`createRecord` or `updateRecord`). In
    particular, it will update the properties of the record that was saved.

  extractSingle: function(store, primaryType, payload, recordId, requestType) {
    payload = this.normalizePayload(primaryType, payload);

    var primaryTypeName = primaryType.typeKey,
        primaryRecord;

    The primary record has special meaning when responding to `findQuery`

    list of records in the record array that kicked off the request.

    If your primary array contains secondary (embedded) records of the same type,
    you cannot place these into the primary array `posts`. Instead, place the
    secondary items into an underscore prefixed property `_posts`, which will
    push these items into the store and will not affect the resulting query.

  // 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:

    ```js
    App.Comment = 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.

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      serialize: function(post, options) {
        var json = {
          POST_TTL: post.get('title'),
          POST_BDY: post.get('body'),
          POST_CMS: post.get('comments').mapProperty('id')
        }

        if (options.includeId) {
          json.POST_ID_ = post.get('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.

    ```js
    App.ApplicationSerializer = DS.RESTSerializer.extend({
      serialize: function(record, options) {
        var json = {};

        record.eachAttribute(function(name) {
          json[serverAttributeName(name)] = record.get(name);
        })

        record.eachRelationship(function(name, relationship) {
          if (relationship.kind === 'hasMany') {
            json[serverHasManyName(name)] = record.get(name).mapBy('id');
          }
        });

        if (options.includeId) {
          json.ID_ = record.get('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.

    ```js
    App.PostSerializer = DS.RESTSerializer.extend({
      serialize: function(record, options) {
        var json = this._super(record, options);

        json.subject = json.title;
        delete json.title;

        return json;
      }
    });
    ```

    @method serialize
    @param record
    @param options
  */
  serialize: function(record, options) {
    return this._super.apply(this, arguments);
  },

  /**
    You can use this method to customize the root keys serialized into the JSON.
    By default the REST Serializer sends camelized root keys.
    For example, your server may expect underscored root objects.

    ```js
    App.ApplicationSerializer = DS.RESTSerializer.extend({
      serializeIntoHash: function(data, type, record, options) {
        var root = Ember.String.decamelize(type.typeKey);
        data[root] = this.serialize(record, options);
      }
    });
    ```

    @method serializeIntoHash
    @param {Object} hash
    @param {subclass of DS.Model} type
    @param {DS.Model} record
    @param {Object} options
  */
  serializeIntoHash: function(hash, type, record, options) {
    hash[type.typeKey] = this.serialize(record, options);
  },

  /**
    You can use this method to customize how polymorphic objects are serialized.
    By default the JSON Serializer creates the key by appending `Type` to
    the attribute and value from the model's camelcased model name.

    @method serializePolymorphicType
    @param {DS.Model} record
    @param {Object} json
    @param {Object} relationship
  */
  serializePolymorphicType: function(record, json, relationship) {
    var key = relationship.key,
        belongsTo = get(record, key);
    key = this.keyForAttribute ? this.keyForAttribute(key) : key;
    json[key + "Type"] = belongsTo.constructor.typeKey;
  }
});

})();

/**
  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.

  ## 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
  {
    "post": {
      title: "I'm Running to Reform the W3C's Tag",
      author: "Yehuda Katz"
    }
  }
  ```

  ### 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:

  ```js
  App.Person = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    occupation: DS.attr('string')
  });
  ```

  The JSON returned should look like this:

  ```js
  {
    "person": {
      "firstName": "Barack",
      "lastName": "Obama",
      "occupation": "President"
    }
  }
  ```

  ## Customization

  ### Endpoint path customization

  Endpoint paths can be prefixed with a `namespace` by setting the namespace
  property on the adapter:

  ```js
  DS.RESTAdapter.reopen({
    namespace: 'api/1'
  });
  ```
  Requests for `App.Person` would now target `/api/1/people/1`.

  ### Host customization

  An adapter can target other hosts by setting the `host` property.

  ```js
  DS.RESTAdapter.reopen({
    host: 'https://api.example.com'
  });
  ```

  ### Headers customization

  Some APIs require HTTP headers, e.g. to provide an API key. An array of
  headers can be added to the adapter which are passed with every request:

  ```js
  DS.RESTAdapter.reopen({
    headers: {
      "API_KEY": "secret key",
      "ANOTHER_HEADER": "Some header value"
    }
  });
  ```

  Creating an inflector with no rules.

  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, '');

/**
  The ActiveModelAdapter is a subclass of the RESTAdapter designed to integrate
  with a JSON API that uses an underscored naming convention instead of camelcasing.
  It has been designed to work out of the box with the
  [active_model_serializers](http://github.com/rails-api/active_model_serializers)
  Ruby gem.

  This adapter extends the DS.RESTAdapter by making consistent use of the camelization,
  decamelization and pluralization methods to normalize the serialized JSON into a
  format that is compatible with a conventional Rails backend and Ember Data.

  ## JSON Structure

  The ActiveModelAdapter expects the JSON returned from your server to follow
  the REST adapter conventions substituting underscored keys for camelcased ones.

  ### Conventional Names

  Attribute names in your JSON payload should be the underscored versions of
  the attributes in your Ember.js models.

  For example, if you have a `Person` model:

  ```js
  App.FamousPerson = DS.Model.extend({
    firstName: DS.attr('string'),
    lastName: DS.attr('string'),
    occupation: DS.attr('string')
  });
  ```

  The JSON returned should look like this:

  ```js
  {
    "famous_person": {
      "first_name": "Barack",
      "last_name": "Obama",
      "occupation": "President"
    }
  }
  ```

  @class ActiveModelAdapter
  @constructor
  @namespace DS
  @extends DS.Adapter
**/

DS.ActiveModelAdapter = DS.RESTAdapter.extend({
  defaultSerializer: '_ams',
  /**
    The ActiveModelAdapter overrides the `pathForType` method to build
    underscored URLs by decamelizing and pluralizing the object type name.

    ```js
      this.pathForType("famousPerson");
      //=> "famous_people"
    ```

    @method pathForType
    @param {String} type
    @returns String
  */
  pathForType: function(type) {
    var decamelized = Ember.String.decamelize(type);
    return Ember.String.pluralize(decamelized);
  },

  /**
    The ActiveModelAdapter overrides the `ajaxError` method
    to return a DS.InvalidError for all 422 Unprocessable Entity
    responses.

    A 422 HTTP response from the server generally implies that the request
    was well formed but the API was unable to process it because the
    content was not semantically correct or meaningful per the API.

    For more information on 422 HTTP Error code see 11.2 WebDAV RFC 4918
    https://tools.ietf.org/html/rfc4918#section-11.2

    @method ajaxError
    @param jqXHR
    @returns error
  */

    var error = this._super(jqXHR);
