=== Release 0.7 ===

Hobo 0.7 is tested against Rails 1.99.1 (aka Rais 2.0 RC2)

DRYML

  Switched to dashes instead of underscores for tag and attributes
  names. These are converted to underscores in the underlying ruby
  code.

  Unification of tempalte tags and non-template tags. There is now
  only one type of tag and two different ways to call a tag:

    <my-tag>content directly inside the tag</my-tag>

    <my-tag>
      <a-parameter:>Content inside a named parameter (note the colon)</a-parameter>
      <another-parameter:>Some more content</another-parameter>
    </my-tag>

    Note that these styles cannot be mixed. If there is a parameter
    inside a tag call, there must be only parameters (and whitespace,
    which is not output)

    In the first style, the call is implicitly equivalent to:

        <my-tag>
          <default:>content directly inside the tag</default>
        </my-tag>

    And by the same token, <tagbody/> is now written:

      <do param="default"/>

    The tagbody local variable is gone too. "if tagbody" is now
    "if all_parameters.default?" and "tagbody.call" is now
    "all_parameters.default"


  A rake task hobo:fixdryml has been added which does a pretty good
  job of converting Hobo 0.6 DRYML source-code to the new style. It
  will change every file in app/views/**/*.dryml, and keeps a backup
  copy of app/views in app_views_before_fixdryml. If you pass it CSS=y
  and ID=y it will 'dasherize' css classes and IDs too, which is the
  new Hobo concention. You can also pass DIR=... if you want to point
  it somewhere other than app/views. It won't fix anything in erb
  scriptlets, e.g. use of the tagbody local variable. Expect to do
  some manual fixes after running the task (good job you've got that
  thourough test suite eh?)

  The add_classes helper now automatically dasherizes all class names.

  New helper 'element'. Use in place of Rails' tag and content_tag
  helper. It dasherizes attributes given as symbols.

  
Migration generator

  Better support for STI. It no longer wants to generate tables for
  the subclasses. Stil needed: a way of integrating fields declared in
  the subclasses -- they are currently ignored by the generator.


Hobo Rapid

  In place editiing (and Ajax in general) will now provide the form
  authentication token (CSRF protection) if available. No need to
  disable protect_from_forgery any more.


  Stylesheets:

    Removed list-style: none from hobo_abse.css


  Javascript:

    Dasherized all css classes and dom IDs used.

    Upgraded to latest low_pro.js

  
  New theme 'Clean'

  New helper 'linkable?' can be given a record or class, and tells you
  if Hobo has a route for it. Only works for 'show' and 'index'
  actions so far.

  Tag library

    \\'/;p <a> now automatically knows not to generate (broken) links to
    things that are not 'linkable?'. Outputs just the link content
    instead.

    We used to have <FieldList> and <field_list>. We now have
    <field-list> and <labelled-item-list>

    <UL> is now <ul>, and only has the iteration behaviour if you give
    a <li:> parameter. Otherwise it's just like a static tag.

    <Table> is now <table> and only has the special behaviour if you
    give a 'fields' attribute or '<tr:>' parameter. Otherwise it's
    just like a static tag.

    <view> for dates and times no longer break when the context is
    nil.

    <count> - unless-none attribute is gone. user if-any

    <theme-stylesheet> now takes a 'name' attribute

    <delete-button> takes a 'subsite' attribute
    

Rake tasks

  New task hobo:fixdryml (see DRYML section above)

  dump_fixtures is now hobo:fixtures:dump




Hobo models

  Automatically declares the field 'position :integer' if the model
  acts_as_list.

  never_show declarations are now inherited

  Fix: def_scope was broken when the scope name ended '?'

  Fix: Hobo broke the 'guard_protected_attributes' optional parameter
  to attributes=. (this was breaking attachment_fu)

  Fix: assigning Date and Time objects in mass-assignment was broken.


User model

  Newly generated user models (hobo_user_model generator) now give
  create permission to all by default (to enable signup).

  logins_count renamed to login_count (Hobo manages this feild for you
  if it exists).


Core extensions

  Module#alias_tag_chain, which never should have been there is
  gone. (It's not needed now that camel-case tags have gone).



  















=== Release 0.6.4 ===

Fix: In-place-editors were not working with the new version of
Scriptaculous

The default fade effect on in-place-editors is now disabled

<ShowPage> now has a title


=== Release 0.6.3 ===

New feature: subsites, i.e. namespaced routes, plus support in the
controller and view layers. Subsites are created automatically for any
directories found in app/controllers. Links default to the current
subsite unless you give a subite="..." attribute. The taglib
app/views/<subsite>/<subsite-name>.dryml is automatically included in
every page in the subsite.

The out-of-box app is not in great shape in this release, mostly due
to problems with the theme. We haven't fixed it because the theme
system going to change radically in Hobo 0.7

New version of lowpro, compatible with Prototype 1.6 (rev 267)

Change to hobo command:

  hobo [...options...] app-name

  instead of

  hobo app-name [...options...]


Migration generator

  Automatically ignores non-Hobo models (and associated tables) 

  Hobo::Migrations.ignore_models is now deprecated.

    Use Hobo::Migrations.ignore to list models that should be
    ignored. The associated tables are ignored too (rarely needed, as
    these are probably not Hobo models anyway)

    Hobo::Migrations.ignore_tables is still supported

  Fix: problems with going back to a nil default from a non-nil
  default.


Hobo model generator

  In line with Rails 2.0, the timestamps declaration is now included
  by default (it's generally something every model should have).


hobo_base.css

  Removed over-zealous styling of too many elements.


hobo_rapid.css

  Change of class names for validation errors.


hobo_rapid.js

  Now silently ignores update to non-existent part. This is convenient
  when parts are being added dynamically, but may prove to be a
  mistake :-)

  Global variable controllerNames is gone. Now use calls to
  Hobo.pluralise. (Gee I guess we should really standardise on
  American spellings)

  The 'fade' parameter to removeButton is now an option. Confirmation
  is now optional too.

  Hobo.partFor returns the part containing a given element. Used in
  the new update="self" feature.

  LowPro behaviour HasManyThroughInput. This is badly named and will
  change.


Core extensions

  alias_tag_chain is like alias_method_chain but for DRYML tags

  SafeNil

    Now more efficient (thanks to "steve d" --
    http://coderrr.wordpress.com)

    Fix when used with DelegateClass

  New method #implies on booleans. Borrowed from Eiffel. Useful in
  permission methods.

    true.implies false #=> false
    true.implies true  #=> true
    false.implies x    #=> true

  Hash#map_hash. The block is passed only the value if the arity is 1.


DRYML

  The ability to define tags in Ruby is now removed

  Tag extension: <def tag="Page" extend_with="navigation">

    This encapsulates the alias_method_chain pattern. The tag can make
    a call to <PageWithoutNavigation> to get the old behaviour.

    alias_current_as is gone -- replaced by extend_with

  Fix: some DRYML attributes were leaking through to the output HTML

  part_locals can now be passed instance variable names,
  e.g. part_locals="@user". Note that inside the part this creates a
  local variable "user". Don't user @user inside the part. It's just a
  convenience to avoid the need to do <set user="&@user"/>
  
  Fix: failure to accumulate CSS class names when merging attributes.

  DRYML now gives the type returned by #field_type (when available)
  over this.class

  Fix: when overriding a parameter, the <default_tagbody/> of the new
  parameter would incorrectly provide the old tagbody which should
  have been overridden.

  hoboParts variable is now set by <hobo_rapid_javascripts> rather
  than being hard wired in the output from the DRYML compiler.

  Fix: caching problems with tags imported by the include_tablib
  directive.


AJAX Parts

  Calls to parts, along with the part-state variables are now logged.

  Can now say part="self" when a tag wants to update the part it is
  contained in (useful for re-usable tags).


Rich data types

  All rich data types now register themselves with Hobo, e.g.

    class Hobo::EmailAddress < String
      COLUMN_TYPE = :string
      ...
    end

    Hobo.field_types[:email_address] = Hobo::EmailAddress

  New type builder - enum_string. e.g.

    fields do
      gender enum_string(:male, :female)
    end

    You can then do, e.g. if current_user.gender.male?

    (You also automatically get select menu's in your views)


Hobo models

  In fields declaration: 

    Got rid of weird thing where providing :length meant the type
    defaulted to :string

    Can now give classes as well as symbolic names for column types.

  Mass attribute assignment extended to support some features that
  were in the model controller. e.g. Dates can be represented as
  Hashes of month, day etc. Chronic will be used to parse dates if
  available. Object references (e.g. belongs_to relationships) can be
  set with "@<typed-id>" as before. 

  "fields do" can optionally be used with a parameter if you don't
  like the instance_eval hackery:

    fields do |f|
      f.name :string
    end

  belongs_to can be given :null => false, which is passed through to
  the migration generator.

  New method #column returns the meta-data for the named column.

  #find now returns arrays with a #member_class method

  def_scope

    Chained scopes on a class didn't work at all -- now fixed,
    e.g. Posts.recent.by_author.find(:all)

    Fix: def_scope with sql parameter interpolation was broken.


  #changed_fields, which was next to useless, replaced with
  #only_changed_fields, which is used to assert that only the given
  fields have changed.


Hobo user model

  The module is renamed from Hobo::AuthenticatedUser to just
  Hobo::User

  It is no longer possible to set the login attribute by passing a
  symbol to hobo_user_model. Go back to using set_login_attr. Didn't
  work out. It happens sometimes.


Helpers

  #subsite returns the name of the current subsite.

  #object_url can now be passed the siubsite, e.g. :subsite => "admin"

  #object_url can only be passed a single hash of options now (could
  be passed any ammount before)

  #dom_id now returns "" when a dom_id cannot be generated (used to
  raise an error)
    
  #map_this now works with ranges (used by DRYML's repeat)

  #current_page_url returns request.request_uri without the query string

  #query_params now returns a HashWithIndifferentAccess

  Hobo.dom_id now works better with non-hobo models


Permission System

  Fix: view permission was causing errors with non-hobo models. Now
  defaults to viewable.


Hobo Controller

  include_tablib accepts symbols as well as strings

  #redirect_to now forwards all params to object_url when not given a
  String, Symbol or Hash

  #hobo_ajax_response no longer need be passed a dryml this


Model controller

  Multiple model creates / updates are gone from the controller
  layer. Hobo now uses good ol' Rails mass attribute
  assignment. Coping with multiple object updates should be handled in
  the model layer. Some features from the model controller have been
  moved to the model layer, and more will be added in the future.

  Attempts to automatically re-render the correct page after a
  validation error on create / update using a form parameter
  "page_path", which the <form> tag provides in a hidden
  field. Previously assumed the form came from the new / edit action.

  Automatic pagination is now only applied to appropriate
  mime-types. Add mime-types to Hobo::ModelController.PAGINATE_FORMATS
  to have them paginated.

  New declaration 'auto_actions' allows you to select which actions
  Hobo provides for you automatically. 

    # White list
    auto_actions :show, :index

    or

    # Black list
    auto_action :all, :except => [ :new_comment ]

    You can use :collections to add/remove all collection actions in
    either the black or white list.

  New declaration 'index_action' declares a new index-like action
  (similar to show_action)

  index_action, show_action and web_method can now all be given
  blocks, rather than defining a method of the same name:

    show_action :summary do
      hobo_show Post.find(params[:id], :include => :comments)
    end

  Web methods now automatically respond with hobo_ajax_response if the
  method does not respond.

  #search

    Now less magic (i.e. doesn't operate by side-effecting). It now
    returns a condition string suitable to be passed to :conditions.

    Can be given a model as the first argument to search on a
    different model (e.g. for show-collection actions).

  Fix: :paginate => false was broken

  #create, #update and #destroy now set flash messages by default
  (only on "wants.html" requests)

  <PermissionDeniedPage> used as the default permission denied
  response.

  <NotFoundPage> used as the default 404 response.
  

User controller

  Added various customisation options to login and signup

  On login, redirect to #home_page -- you can override this on your
  controllers.

  The actual name of the login attribute (e.g. "email", "username") is
  now used in flash messages.

  hobo_logout can now be given a block to customise the response.

  Fixes for validation errors on signup.


Routing

  Routes for non-existent actions are not generated.


Tag library: Core tags

  <wrap> will wrap its content in ther tag specified by tag="..." if
  when="..." is true.

  Fix: <unless> -- was behaving like <if>


Tag library: Rapid

  <FieldList> now has params <label> and <view> that wrap every label
  and view. Also <foo_tag> where "foo" is a field-name, is the actual
  tag that renders the field (e.g. <view> or <edit>)

  <nil_view> can be overridden to customise the way Hobo renders nil
  values.

  <Table> new attribute 'empty' -- when given the table is rendered
  even when there are items in the collection.

  <name> now respects view permission properly

  <view> now does a #strip to the output

  <count> -- new attribute if_any - set to true to output nothing if
  the count is zero.


Tag library: Rapid documents

  The 'document' tags like <section>, <aside> output nothing when the
  content is blank. Now they can ge given the 'empty' attribute
  causing the tag to be output even if the content is blank.

  New tag <sub_heading>


Tag library: Rapid forms

  <hidden_fields> will now not output hidden fields for attributes
  on new records that are in their default state.

  <form> now has a default ajax message for creating new objects.

  <form> now supports forgery protection

  <input> -- better handling of the 'field with errors' wrapper

  <input> for passwords now accepts extra html attributes

  New <input> for enum-strings - a select menu.

  New <input> for big decimals 

  <remote_method_button> now supports non ajax remote method calls
  (when no update="..." is given)

  css classes on buttons renamed from "button_input" to "button"

  <update_button> now supports confirm="&false"

  <belongs_to_menu_input>

    none_message attribute renamed to blank_message

    Conditions on belongs_to are now observed (only eligible records
    are in the menu)

  New <ErrorMessages> template tag - like the error_messages_for
  helper with added Hobo goodness.


Tag library: Rapid navigation

  <page_nav> now hides without errors if there is no @pages object

  <nav_item> now ignores nested tags when selecting the current nav
  item.


Tag library: Rapid pages

  Significant re-factoring of all page tags -- see source :-)

  <javascript name="a, b, c"> tag - like helper javascript_include_tag

  New pages <NotFoundPage> and <PermissionDeinedPage>


Tag library: Rapid support

  <TablePlus> various new params


=== Release 0.6.2 ===

Specs

  Moved out of the plugin source into a separate directory in the
  hierarchy. If you check out hobo/trunk you'll get two directories:
  hobo and hobo_spec. You can run "rake" from the hobo directory and
  it should work as long as hobo_spec is along side. Note the
  hobo_spec tree contains an svn external to edge rails.


New rake task dump_fixtures (which really should be nicely
namespaced). This will dump the current database into test
fixtures. The nice part is that it won't overwrite symbolic names
you've given to rows in your fixtures, so you can round-trip with it:
rake db:fixtures:load, run up the app and create some new data, rake
dump_fixtures. 


Migration generator

  Fixed indentation bug in generated code.

  Now prompts for the name of the generated migration after the
  generated code is displayed.

  Better error message for invalid field types declared in models.


Tabla theme

  Fixed reference to non-existent human_type helper.


Hobo users

  Various fixes to the new (in 0.6.1) multiple user model support.

  If the model name is "User", the routes generated are simply:

    /login  
    /logout
    /signup

   (as opposed to /user_login etc.)

  The filter "login_required" can now be passed a user model (class),
  e.g.

    before_filter {|controller| controller.login_required(Administrator) }

  The named routes "login", "logout" and "signup" are no longer
  defined. Instead there are helpers login_url, signup_url and
  logout_url, all of which are passed a user model (class) as
  parameter.

  New declaration 'hobo_user_model' can be used in place of hobo_model
  and removes the need to include Hobo::AuthenticatedUser. Can be
  passed the name of the login field, which removes the need to call
  set_login_attr. Can also be passed a block in which to do
  validations of the login attr (just as you can with set_login_attr).

  User models now have a class method login_attr that returns the name
  of the login attribute, e.g. :username

  Guest model should now extend Hobo::Guest, which provides #guest
  (true!) and #super_user (false)

  User models now inherit #guest? (returns false). No need to define
  it yourself.


Hobo models

  Optimisation. Where possible we've replaced calls to #respond_to?
  (which is slow on AR records) with the new class method
  #has_hobo_method? which is an alias for
  #respond_to_without_attributes?

  "fields do" now supports shorthands for common validations
  validates_uniqueness_of and validates_presence_of, e.g.:

    fields do
      name :string, :required, :unique
    end

    If you need to change the validation method, just go back to the
    old way.

  The creator attribute mechanism is updated to cope with multiple
  user models. Hobo will not try to set the creator attribute if the
  expected type is not the same as the type of the logged in user.

  Various enhancements to composable query blocks

  MyModel.has_creator? replaced with MyModel.creator_type which
  returns the expected user class or nil if there is no creator
  attribute.

  Fix: def_scope was broken with has_many :through associations.


Integration test helpers

  #logs_in_as updated to cope with multiple user types.


Core extensions

  New method Object._? can be used to avoid an extra test for nil, e.g.

    string_or_nil._?.length

    is equivalent to 

    string_or_nil && string_or_nil.length

  Hobo extensions to HashWithIndifferentAccess fixed to always return
  indifferent hashes.

  
Hobo controller

  Fix to #render_tags (problem with part contexts javascript)

  Fix to include_taglib declaration (was not working in production
  mode).


Hobo model controller

  Largely re-written handling of http PUT and POST (update &
  create). The new mechanism is more secure, more featureful and is
  transactional. If your put/post affects multiple database rows, they
  will either all happen or none will. See the model_controller_spec
  for some good examples of what is allowed / possible.

  def_data_filter is gone. Instead you can declare data filters from
  within the action methods:

    def index
      data_filter :search do |query|
        name_contains(query) | address_contains(query)
      end
      hobo_index
    end

    Declare data filters for autocompleters in the same way by giving
    a block to autocomplete_for

  #index now supports a "sort" parameter. The value should be
  <field-name> or <model>.<field-name>. Precede with a '-' to sort in
  descending order. e.g.

    http://host/users?sort=-username

    Provide the :order parameter to hobo_index to disable.

  The mechanism to call a tag <ShowPage> if there is no show.dryml is
  extended to work with any action name. So e.g. you can define
  <FooPage> as an application wide page for any action "foo".


Hobo user controller

  Options can now be given as procs, in which case they are called
  only when needed and hence have access to things like current_user
  (e.g. the redirect destination for a logged in user can take into
  account who the user is)

  #hobo_login can be given a block -- a place to check if the users
  account is available. Return false to prevent the user from loggin
  in.


Hobo module

  #can_view? can now be given dotted field paths. E.g:

    Hobo.can_view(current_user, post, "author.name")


Hobo Rapid

  Adding low_pro.js (from the UJS project). First step towards
  complete adoption of unobstrusive JavaScript.

  Fix to client side of new ajax mechanism. Had problems with not URL
  encoding part state.

  New taglib rapid_plus, home of tags with an extra level of
  functionality. First and only tag: <TablePlus> a table with
  automatic support for sorting by clicking on column headings, and
  filtering rows via a search field.

  <Table> now supports tempalte parameters for each cell when given a
  'fields' attribute, e.g. <name_view> <address_view> (<name_cell>
  might seem like a better name, but we wanted to be compatible with
  <FieldList> so it's easy to flip back and forth).

  <name> tag now respects view permission.

  <a action="new"> now only renders the link if the current user has
  the required create permission.

  <view> now supports attribute 'truncate'

  <view for_type="Date"> now supports a 'format' attribute - a
  strftime style format string.

  New tag <restricted_page>. Sometimes permissions are a view layer
  concern - you actually want to say "these colors, this logo,
  etc. are only to be seen by the administrator".

    <restricted_page login_required="Administrator"/>

  New tag <you_have>. An easy way to say either "You have 3 posts in
  this thread" or "Fred Blogs has 3 posts in this thread", depending
  on whether Fred Blogs is the current user.

  Fixes to the tags in rapid_documents to avoid evaling tagbody twice.

  <hidden_fields> fixed (was outputing hidden fields even when the
  field existed in the form). Also now support "for_query_string"
  attribute, to output hidden fields for the name/value pairs in the
  current query string.

  <form> now sets a scoped variable "in_form" so tags can behave
  differently when they are inside a form (FieldList does this).

  <input> for datetime and date now supports the same attributes as
  the equivalent rails helpers. e.g. you can change the order of the
  fields.

  <belongs_to_menu_input> can now be passed an array of records in the
  "options" attribute (instead of retrieving the entire target table
  from the DB).

  Fixes to page navigation

  <account_nav> upgraded to cope with multiple user models.

  Rapid pages:

    Various new template params made available, including many on
    login and signup pages.

    <Page> updated for multiple user models

    <IndexPage> fix to ajax updating of record count

    New css classes added to <NewPage> and <EditPage>

    <error_messages> added to <EditPage>

    Fix to new link in <ShowCollectionPage>

    <image> tag removed from default ajax progress.
    
       

Dryml

  Important change ommitted from 0.6 changelog - attributes passed to
  the tag that are not in the tags declared attributes are available
  in a local variable "attributes" (used to be called "options").

  <set> can now assign to dotted named (object attributes) as well as
  locals, and can have controll attributes on it (e.g. if)

  Fix to replacing template parameters that are themselves templates.

  When a boolean is in context, this_type is now always TrueClass
  (never FalseClass even if the value is false). TrueClass is the Hobo
  boolean type.

  #render_tag on a page renderer object (Dryml internals) now returns
  false. This alows Hobo's controller to say "call this tag if it
  exists, otherwise..."


Rich types

  Registered rich types can now provide there own validations that get
  added to the model automatically. E.g. Hobo::EmailAddress
  automatically validates the content as a valid email address.


Hobo helpers

  New helper query_params returns a hash of parameters extracted from
  the query string only (#params returns route-based parameters
  too). Only works with simple name=value parameters.


=== Release 0.6.1 ===

Multiple user models

  Hobo now supports multiple user models, with independent sign-up /
  log-in/out for each. 

  The controller needs to declare hobo_user_controller instead of
  hobo_model_controller (it still has all the hobo_model_controller
  features). e.g.

    class AdminsController; hobo_user_controller; end

    Hobo routing will automatically give you

      /admin_login
      /admin_logout
      /admin_signup

    Note this controller will now filter logging of passwords.

  The model needs to include Hobo::AuthenticatedUser and declare a
  login attribute with, e.g.

    set_login_attr :email

  The hobo_front_controller generator no longer generates anything
  related to users - it's now just the fron page and search page.

  There is a new hobo_user_model generator to create these
  controllers.

  The global value Hobo.user_model is gone

  Rapid now has <LoginPage> and <SignupPage> templates. They're not so
  customisable just now but you can of course replace them completely
  with your own views.


Misc fixes

  Search was broken

  The 'hobo' command tried to connect to the DB, which was a problem
  as you'd had no chance to configure database.yml


Rapid

  Fix: reset_form and refocus form options

  <Table> now supports @fields, allowing you to give a bunch of field
  names and automatically have a table with a column for each of those
  fields. There's also a <controls> param that can be used to have a
  delete button and edit link on each row. As usual there's a ton of
  customisation options - see the source.

  <human_type> is now <type_name> and takes flags @plural and @lowercase

  <editor> and <input> have better automatic css classes

  Restored old behaviour where <page_nav/> would display nothing when
  there's only one page.

  Finally created <EditPage>

  Small cleanups in the rapid pages

  New tag <with_field_names/> used in <Table> to iterate over the
  column headings.

  <view> for Time objects now supports @format - a strftime style
  format string.



Migration generator

  Fix: Edge Rails now dumps out in sexy format, which was freaking the
  migration generator.

  You can now configure the generator to completely ignore specified
  tables and models. In environment.rb do

    Hobo::Migrations.ignore = %w(red_fish blue_fish)

    That will ignore the models RedFish and BlueFish, and the tables
    red_fishes and blue_fishes

    To ignore just tables, assign an array of their names to

      Hobo::Migrations.ignore_tables

    To ignore just models, assign an array of the class names to 

      Hobo::Migrations.ignore_models

New secure ajax parts mechanism

  The new mechanism stores the part state in a base 64 encoded string,
  complete with an SHA1 (by default) digest, so malicious tampering
  with the part state is prevented.

  Parts can now capture the state of local variables along with the
  DRYML context. Give a list of locals you wish to capture in the
  'part_locals' attribute. e.g.

    <div part="my_part" part_locals="a, b"> ... </div>

  (the inability to do this was a serious limitation of the previous
  mechanism)


Core extensions

  Added Methodphitamine and removed omap, oselect, ofind, oany oall.

    See http://jicksta.com/articles/2007/08/04/the-methodphitamine


DRYML

  merge_attrs fixed to not complain about nils

  Fix: css classes were not accumulated in some template parameter
  situations


Hobo module

  #type_name renamed to #type_id

  #object_from_dom_id will now return classes when the id has no, er, id. As in

    Hobo.object_from_dom_id("blog_post") #=> BlogPost

  Similarly, #dom_id generates those kind of ID for classes


=== Release 0.6 ===

DRYML

  Local tags are gone. We finally gave up on this feature as too
  complex.

  New feature - <set_scoped> allows a variable assignment that exists
  only for the lifetime of the tag-body of <set_scoped/>. At the end
  of the block, the previous value of the variable, if there will be
  restored. This feature gives a lot of the power of local tags in a
  less pure but far simpler mechanism.

  New feature - polymorphic tags. A tag can have many definitions for
  different types of object. Define with e.g.

    <def tag="card" for="User"/>...</def>
    <def tag="card" for="BlogPost">...</def>
  
    call with <card for_type/>

    The actual tag called will be selected according to the type of
    the current context.

  Core tags moved from lib/hobo/core.rb to tags/core.dryml. This
  follows on from the deprecating of def_tag

  Fix: attrs_for now works with tags imported from a taglib

  Gone: template parameter modifiers (e.g. <my_param.append>). The
  only one left is 'replace' which is now written as '<my_param
  replace>' and 'replace' is now a reserved attribute name. Two new
  features - default tagbodies and restoring parameters - give the
  same functionality but are more powerful because you can now _wrap_
  a parameter in your own tag.

  New feature - default tagbodies. Tags can provide a default tagbody
  like this:

    <def tag="foo">...<tagbody>this is the default</tagbody>...</def>

    Callers can keep the default: <foo/>
    replace it <foo>my tagbody</foo>
    or wrap it in new content: <foo>&ldquo;<default_tagbody/>&rdquo;</foo>

    You can give restore the default tagbody of an element further up
    the hierarchy using the 'for' attribute. e.g:

      <foo><baa>&ldquo;<default_tagbody for="foo"/>&rdquo;</baa></foo>

  New feature: restoring replaced template parameters. For example -
  wrapping a template param in an extra div:

    <MyTemplate>
      <my_param replace><div><my_param restore/></div></my_param>
    </MyTemplate>

  def@alias_current renamed to 'alias_current_as'

  @if and @unless controll attributes always test for non-blank rather
  than true. This is more convenient in DRYML where we generally want
  to skip stuff if a collection is empty (empty enumerables are blank,
  but not false)

  An attribute that starts with an XML entity reference is *not*
  considered a code attribute, even though it does start '&'
  e.g. label="&raquo; Next"

  #merge_attrs now always accumultates rather than
  replaces css classes.

  form, input and a have been removed from static_tags - these are now
  defined tags.

  Many core tags moved to Rapid. There are very ferw core tags now - just
  the basic control tags (if, unless etc.)


Hobo Models

  The display_name method is not used anymore. Instead use the new
  polymorphic tags.

    <def tag="name" for="MyModel">...</def>

    The <name> tag eventually falls back on to_s, so as an alternative
    you can rename your display_name methods to to_s.

  New semantics for #new and #build.

    #new now does what new_without_appending used to do. That is, it
    instantiates a new object exactly as if it was in the collection,
    but it does not modify the collection itself.

    #build is extended so that it sets the belongs_to association that
    is the counterpart to the has_many.

    For existing apps, just change any calls to #new_without_appending
    to #new

  Refactored the rich type mechanism to make it easier to add new
  types. To add a new type, e.g.:

    class Isbn < String; COLUMN_TYPE = :string; end

    Hobo.field_types[:isbn] = Isbn

    You can then use :isbn as a field type in 'fields do', and
    register a view with <def tag="view" for="isbn">


  New rich type Hobo::EmailAddress < String

    Doesn't have any special behaviour as yet, but we could do nifty
    things with it in the future like auto anti-spam cloaking,
    validations...

  New method #nillable_field? tests if the underlying collumn can be
  null.

  New methods #created_date and #modified_date return
  [created|modified]_at.to_date

  Default to_s for all hobo_models


Model controller

  Boolean fields now get a false value when the param is either '0' or
  'false'.


Front controller

  All the templates are updated to use the new DRYML


Migration generator

  Now gives an option to generate and run the migration immediately

  Will create the "foo_type" column for belongs_to associations marked
  as polymorphic.


Hobo Rapid

  lib/hobo/rapid.rb is gone. The tags are now in tags/rapid.dryml and
  the helpers are in lib/hobo/rapid_helper.rb

  Now includes two CSS stylesheets. hobo_base.css provides some handy
  reset rules to reduce cross-browser headaches, and hobo_rapid.css
  provides default styling for some of the Rapid components.

  Rapid split up into more separate dryml files: rapid,
  rapid_document_tags, rapid_forms, rapid_pages, rapid_editing,
  rapid_navigation, rapid_support

  There are a great many changes to the Rapid tags, too much to
  describe individually here. The most important changes are:

    <show> becomes <view>. <view> is a polymorphic tag, so you can
    <def tag="view" for="MyClass">

    <edit> is gone. Use <editor> if you want a tag that gives an
    in-place (ajax) editor, and degrades to <view> if the user does
    not have edit permission. <editor> is a polymorphic tag, so you
    can <def tag="editor" for="MyClass">

    <form_field> is now <input>. If you give a type attribute, you
    get a regular html input tag, if you don't you get a smart Hobo
    form field appropriate for the type of the context. <input> is a
    polymorphic tag, so you can <def tag="input" for="MyClass">

    All the special form-field tags tags that ended _field now end
    _input

    <table_for> becomes <Table>

    <ul_for> becomes <UL>

    <object_form> and <remote_method_form> are now both handled by
    <form>

    <object_link> and <new_object_link> are now both handled by <a>

    <object_table> becomes <FieldList>

    <display_name> becomes <name>

    Various small changes to the navigation tags - please see
    rapid_navigation.dryml


Hobo Rapid Javascript

  Fix: problems with the save button in TinyMCE fighting with the
  save-on-blur behaviour.


Tabla theme

  Tweaks to application.dryml and the stylesheet for new DRYML


Hobo user model generator

  Doesn't declare the authentication fields anymore, as these have
  been moved to Hobo::Authenticated user. This is part of the move to
  supporting multiple user models.


Hobo controller & helpers

  ControllerHelpers are now HoboHelper, and there's a change to the
  way this is included in both the controller and the view.

  #render_tags extended to support polymorphic tags

  #site_search now renders the polymorphic <card> tag for each search
  result.


Hobo module

  New method Hobo.symbolic_type_name returns a symbol abbreviation for
  a rich type. e.g. Hobo.symbolic_type_name(Hobo::Text) #=> :text

  New method Hobo.type_name

    Hobo.type_name(MyModule::MyClass) #=> "my_module__my_class"

    Note the double underscore


Core Extensions

  ActiveSupport's HashWithIndifferentAccess is extended to keep it's
  indifferent access semantics with Hobo's extensions to Hash.



=== Release 0.6-pre1 ===

*NOTE* We are now using Edge Rails for all our tests. YMMV with other
 Rails releases. If you do upgrade tp Edge Rails, you'll need to
 install classic_pagination too (this dependency will probably go away
 at some point)

hobolib directory (app/views/hobolib) renamed to 'taglibs'


DRYML

  Hobo::DefineTags and def_tag are deprecated - they'll be phased out.

  Code attributes changed from foo="#baa" to foo="&baa"

  Changing the context:

    obj="..." renamed to with="..."

    attr="..." renamed to field="..."

    Shorthand syntax <show:authtor.name/> equivalent to <show field="author.name"/>
    Note that the ':' and field name(s) are optional on the close tag, e.g.:

      <repeat:comments> ... </repeat>

    (Be aware that your DRYML is no longer valid XML if you go for this option)

  <taglib> renamed to <include>

  part_id="..." renamed to part="..."

  #{...} is now supported in attributes of static tags (i.e. plain HTML tags)

  <include> (formerly <taglib>) now supports the 'as' attribute for
  putting tags in namespaces.

    <include src="my_taglib"/>, then... <my_tag/>
    <include src="my_taglib" as="foo"/>, then... <foo.my_tag/>

    (note that <foo.my_tag/> compiles to simple "foo.my_tag()", i.e. a
    method call on an object, so you can do other stuff with this if
    the mood takes you)

  xattrs="..." renamed to merge_attrs="..."

  New feature: template tags

  Parameter tags (<:foo>...</:foo>) are gone. Replaced by template
  parameters.

  content_option and replace_option are gone. The 'param' attribute is
  the new equivalent (part of template tags)

  <else> can now be used in many places. e.g. after <repeat>, the else
  content will be used if the repeated collection is empty.

  Attributes can now have no RHS, e.g.

    <logo small/> is equivalent to <logo small="&true"/>

    (note your DRYML is not valid XML if you use this shorthand)

  #attrs_for can be called for any tag and return the declared
   attributes on the tag. e.g.

    attrs_for(:foo) #=> [:a, :b] -- assuming <def tag="foo" attrs="a, b">

  New feature: local tags, e.g.

    <def tag="a">
      <def tag="panel">...</def>
      
      ... Any call to panel in here, or in the tagbody of the call to
      <a> will get the local definition. Note that local tags are full
      closures and have access to state from the containing tag...
    </def>

  <set a="&1" b="&2"/> equivalent to <% a = 1; b = 2 %>

  New feature: polymorphic tag calls. e.g. if the current context is a
  User <card for_type/> will try to call <user_card/>, falling back on
  just <card/> if no such tag exists.

  New feature: control attributes

    <p if="..."/> as a shorthand for <if q="..."><p/></if>
    <p unless="..."/> as a shorthand for <unless q="..."><p/></unless>
    <p repeat="..."/> as a shorthand for <repeat with="..."><p/></repeat>

    Think of these as the dryml equivalent of the suffix 'if' and 'unless' in Ruby.

    If you give the attributes a string, it is treated test for a
    non-blank field, e.g.  if="address" is like 
    <if q="&!this.address.blank?">

    You can use <else> after tags with these attributes on them.

  Fix: calling @view methods with a block now works

  The list of tags considered 'static' (i.e. plain HTML tags) can now
  be customised by putting your own list (one tag per line) in
  config/dryml_static_tags.txt


Hobo Controllers

  New directive "include_taglib" allows a specific DRYML taglib to be
  included in every action on this controller.

  render_tag now supports custom render options, e.g.

    render_tag :error_message, { :message => "uh oh" }, { :status => 500 }

  Options passed to #hobo_index are now also forwarded to
  #paginated_find, making it easier to change the page size etc.

  #paginated_find now takes an :association parameter to provide a
  custom association

  Fix: :order option to paginated_find ignored in some situations.

  Hobo controller actions now perform a #hobo_render if you give a
  response block but the blog does not do a render or a redirect. So
  e.g. if you just want to update the session you can leave hobo to
  handle the response

  Fix: hobo_create now checks for create permission if you pass a
  custom :this parameter

  POSTing and PUTing now support boolean values


Hobo Models

  #created_by renamed to #set_creator. This should help avoid name
  clashes with column names etc.

  Added field declarations on models. This replaces set_field_type and
  also supports the migration generator.

    fields do
      name :string
      body :html
    end

  Added return_type declaration for setting rich types on model
  methods, e.g.

    return_type :html
    def my_method
      ...
    end

    This allows DRYML to render the correct widget even when the
    method is returning nil

  Fix: def_scope was pretty much completely broken

RSpec support and a test Rails app (in spec/rails-root) added to the
repository.


DRYML Core Tags

  <dynamic_tag/> renamed to <call_tag/> 

  <display_name/> displays "(not available)" if the context is nil

  show@no_span renamed to show@no_wrapper, and for content such as
  :html it now generates a div instead of a span.

  count@unless_none -- nothing output when count is zero (can be
  followed by an <else>)

  <join> now uses <display_name> if no tagbody is given.

  join@with renamed to join@separator


DRYML Helpers

  #param_name_for will strip a trailing '?' if there is one.
  

Hobo Rapid Tags
  
  <boolean_field> now also generates a hidden tag with the same name
  and value '0' like the rails helper. This fixes HTMLs broken idea of
  how to handle checkboxes (you get a 0 value if the checkbox is not
  checked, instead of no parameter at all)

  <object_form> no longer generates hidden fields for created_at and updated_at


Hobo::TextileString now includes a monkey-patch to RedCloth


Users & Authentication

  Added: Hobo maintains a login_count attribute if one exists on your user model.


Hobo Rapid Javascript

  Ajax forms now default to not resseting and not refocussing after submission.

  Fix: ajax behaviour (Hobo.applyEvents) now applied to the result of searches.

  Fix: Ajax now using encodeURIComponent instead of escape. Fixes
  problems with foreign characters.


Tabla theme

  Removed <application_logo/>

  Added missing image plus.png


Generators

  New: hobo_migration generator. Creates fully implemented migrations
  for you based on field declarations in your models

    hobo_model and hobo_user_model generators updated accordingly --
    they don't generate migrations any more.

Routes

  Routes with ';' have been changed to use '/' as per edge Rails.

Permission System

  Hobo.can_edit? can now handle feild names that end in '?'

Hobo Module

  Hobo.models now skips files whos names don't look like models
  (e.g. editor backup files)


Core Extensions:

  Add: Enumerable#build_hash

    (1..3).build_hash {|i| ["#{i} Xs", "X" * i]}
    => {"1 Xs"=>"X", "3 Xs"=>"XXX", "2 Xs"=>"XX"}

  Add: Enumerable#map_hash

    (1..5).map_hash { |x| x**2 }
    => {5=>25, 1=>1, 2=>4, 3=>9, 4=>16}

  Add: Hash#-

    {:a => 1, :b => 2} - [:a] #=> {:b = 2}

  Add: Hash#&

    {:a => 1, :b => 2} & [:a] #=> {:a = 2}


Documentation

  Added contributed rdoc to Hobo::AuthenticatedUser (thanks!)


=== Release 0.5.3 ===

Core tags

  Fix: <show> tag was broken - it wasn't displaying the surrounding
  <span> or any associations

  <show> now handles all kinds of Numeric types


DRYML

  DRYML Build cache: reloading unchanged DRYML files in dev mode is
  now *much* faster.


Model extensions

  Fixes to the id_name feature


Hobo model controller

  Fix: :permission_denied_response was not supported on several
  actions


Hobo Rapid

  Hobo::Rapid::TYPE_NAMES added - a hash that maps classes to names
  (symbols) that are used when looking for an editor / form field for
  a given type. Allows you to extend the <edit> tag to support your
  own types.


=== Release 0.5.2 ===

Misuse of classify changed throughout to camelize. Bugs related to
certain model names fixed as a result.

Added Hobo::LazyHash. If a value is a proc, the proc is called on the
first access of that key, and the result of the proc becomes the
value. These are used in the new controller customisation mechanism.


Hobo Rapid

  New ajax options reset_form and refocus_form for ajax forms. Default
  is true

  toggle: new function like Element.toggle in prototype (Hobo uses the
  css class 'hidden' instead of an inline 'style' attribute.

  In place editing: various fixes related to HTML/URL encoding.

  New option 'fade' to delete button. Pass fade="#false" to supress
  the fade effect.

  <hobo_rapid_javascripts> now takes an attribute tiny_mce. Set to
  true to enable TinyMCE support for html editors.

  <hobo_rapid_javascripts> within the <page> tag now available as
  inner-tag 'rapid_javascripts'. e.g. you can do

    <page rapid_javascripts.tiny_mce="#true">
    
    to enable TinyMCE support.

  Removed helper current_user_in?

  Editors now have a css class added automatically:
  "<class>_<feild>_editor", e.g. "person_name_editor"

  In place editors now wrap the content in a div if the editor will be
  a textarea or an html editor (was a span).

  All the buttons now have automatically added css classes like
  "delete_person_button", "create_person_button".

  create_button now uses any passed field values in the check for
  create permission.

  object form now has a css class added: either the model class name, or
  "new_<class>"

  New tag <remote_method_form> for calling remote methods with parameters, either with a traditional 


Model Extensions

  Fix to HasManyAssociation#new (didn't support parameters)

  Added block queries to has_many associations,
  e.g. post.comments.find { published = 1 }

  MyModel[...] equivalent to MyModel.find(...) (Thanks to Jamis Buck's
  tip on his blog)

  New feature: defined scopes

  Field types set by set_field_type are now inherited

  Model#conditions { ... } generates an sql where clause from a query
  block.

  Fix to #subclass_associations with has_many :through

  Method #changed_fields? to complement #same_fields?. Useful in
  permission methods.


Integration test extensions

  #visits now can now be given http get parameters

  #deletes added: bob.deletes(some_object)

  #calls_method added: bob.calls_method(object, some_method)


General extensions

  #extract_options_from_args! added to Kernel

  Object#is_a? extended to support multiple args:

    if foo.is_a?(Symbol, String)

  _why's metaid added to Object

  Added Hash#map_hash. e.g. a new hash with all values incremented
  by 1:

    my_hash.map_hash {|k, v| v+1}


Controller extensions

  redirect_to can be passed an object, equivalent to
  redirect_to(object_url(x)), e.g.

    redirect_to current_user.adverts


Model controllers

  Removed customisation hooks, create_response,
  invalid_create_response, update_response etc.

  New mechanism for customising actions. 

    def create
      hobo_create ...customisation args...
    end

  web_method, show_method, and publish_collection declarations are now
  inherited.


Helpers

  debug can now be passed multiple values you'd like to inspect

  param_name_for now accepts a string as well as an array for the
  field path, e.g. param_name_for(current_user, "account.name")

Core tags

  object_link automatically adds a css class "<class>_link",
  e.g. "person_link"

  Changed default date formatting to to_s(:long) for dates and times.

  New tag transpose_and_repeat, useful for those tables when you wish
  HTML grouped cells by column instead of by row.

  New tag if_blank


Permission system

  Hobo::Undefined#undefined? renamed to hobo_undefined?

  can_edit? now works better with boolean fields

  can_call_<method>? renamed to <method>_callable_by?
  

DRYML

  Fix: options to inner-tags were leaking through to the HTML output.

  Debug feature -- if the <def> tag has an attribute
  hobo_debug_source, the generated ERB source will be output to
  logger.debug

  Dryml now reports an error if a part name occurs more than once

  Inner tag names can now be generated at runtime, this allows
  e.g. the object_table tag to generate inner-tags on the fly for
  every editor and label:

    <object_table fields.name_editor.update="my_part" />

  Go read that last one again - it's awesome

New rake tasks

  environments.rake defines tasks like dev, prod, testing so you can
  e.g.:

    rake prod db:migrate

    (thanks to err.the_blog IIRC)


=== Release 0.5.1 ===

Fix to model extensions: hobo_user_model generator could not complete
because an attempt to access the database before the table exists was
made.

=== Release 0.5 ===

Tabla theme

  Changed some heading levels to be more logical - e.g. now use H2 and
  H3 inside a panel instead of H1 and H2

  Various CSS tweaks

  <page>

    Upgraded to use inner tags

    No longer imports public/stylesheets/application.css by default -
    can easily be added using inner-tags

  <application_nav> and <application_logo> moved into the theme (were
  in Rapid)

Frontpage generator

  Page templates modified to use <:intro>, <:main> etc


hobo_rapid generator

  --import-tags option will add two tags to application.dryml:

    <taglib src="plugins/hobo/tags/rapid"/>
    <set_theme name="default"/>


Plugin initialisation

  Theme no longer set to default in hobo/init.rb. Instead use
  <set_theme> in application.dryml


Core extentions

  Enumerable#map_with_index


Ajax Mechanism

  Render parameters (http parameters) are passed in as a hash of
  requests with numeric keys rather than an array.
  (e.g. render[1][id]=foo rather than render[][id]=foo

  Hobo.ajaxRequest (javascript) now displays error messages in an
  alert box. (Known issue: seems to show these twice for some reason)

  In-place-editor support extended to allow other parts to be updated at
  the same time.

  Automatic mechanism for updating multiple displays of the same field
  after an in-place-edit

  In-place-editor for html fields will now use TinyMCE if installed
  (integrated with Ajax.InPlaceEditor)

  Select based ajax editor for numbers, suited for small ranges,
  e.g. 1 to 10

  Hobo.removeButton (javascript) now supports updating of other parts
  along with the removal.

  Dom attribute "model_id" renamed to "hobo_model_id"

  Fix to Ajax.InPlaceEditor - no longer removes <p> tags

  before_ajax hook. This method is called immediately before the ajax
  response is performed. A chance for the controller to make extra
  instance variabled available to the part methods.

  If a custom JS function is specified for an ajax update
  (render[...][function]=f), this name is no longer camelised - it is
  called as-is.

  The object (render[...][object]=...) is now allowed to be nil

  In-place-editor fields now reset automatically to a preset message
  when the field is blank (e.g. "click to edit")


Core helpers

  Fix: object_url gives correct urls when the action is a web-method
  (controller-name/id/method-name)

  <show> will wrap the displayed content in a <span> with a
  hobo_model_id. This enables the automatic update of multiple
  displays of a field value after an ajax edit.

  <show> uses the new type-system added to Hobo models. The main
  benefit is that values that don't come directly from AR should
  display without problem, and more types are supported (e.g. float)

  <show> supports a format attribute for numbers:
    <show attr="price" format="%.2f"/>

  <show> will not display password attributes (e.g. in your model
  set_field_type :password => :password)

  New tags <show_belongs_to> and <show_has_many> can be overriden to
  handle the way these relationships are displayed by <show>

  display_name moved into core (was in Rapid, but is needed by <show>)

  display_name uses <show>, so will wrap the name in a span with a
  hobo_model_id

  <repeat> supports an 'else' attribute, used when the collection is
  empty.

  Debug methods abort_with and debug are now helpers so they are
  available from views as well as controllers.


User Authentication

  Username validations are customisable - pass a block to
  set_login_attr and do validations in there. Otherwise default
  validations are used.


Hobo::Controller

  hobo_ajax_reponse will use @this if no page context is passed

  
Module defined tags

  Can provide a predicate as a block, e.g. to have a different nav bar onced logged in.

      def_tag :nav, (proc {logged_in?}) do ...
      def_tag :nav do ...

    The tag with no predicate will always take precedence if no
    predicate is true. If the proc has a single parameter, it is
    passed the options hash.


DRYML

  Changes to taglib cache system. 

  A list of known HTML tags is defined in lib/hobo/static_tags. These
  are available as an array by calling Hobo.static_tags. Any tags
  parsed that are not in here are compiled as method calls. Thus the
  order of tag definitions is no longer as critical, making it easier
  to split large taglibs into multiple files. As a result, tag modules
  no longer need to track defined tags in a module variable.

  XML comments now passed through to the generated HTML.

  <set_theme> tag to set current theme. Was previously a configuration
  variable. This way it is easier to change or disable the theme.

  New feature - inner tags

  <def> now supports alias_current attribute, e.g.

    <def tag="page" alias_current="theme_page">

    This overrides the current <page> definition and makes the old one
    available as <theme_page>

  <tagbody> supports obj= and attr= at the same time, as with regular
  tag calls



Hobo models

  New type system. This is the extended type system that allows you to
  say, e.g. `set_field_type :intro => :html`. Previously this was
  returned as a symbol from MyModel.field_type(:intro). The new system
  uses wrapper types (simple subclasses of String), and modified your
  model to return these. e.g.

    MyModel.find(:first).intro.class => Hobo::HtmlString

    There are similar types for textile, markdown, passwords, and text
    (the text type just denotes a longer string, and is used for the
    'text' sql type).


Hobo model controller

  `show_method` renamed to `show_action`

  New class method `publish_collection`. Any `has_many` collections
  are published automatically. This method allows custom collections,
  i.e. model methods that return arrays, to be published also.

  create action for an STI base-class controller can now be used to
  create subclass instances by passing the 'type' parameter.

  update action enhanced to allow a full Hobo ajax-reponse (i.e. part
  updates) after in-place-edits.

  Controllers can define a `find_for_show` method to provide a custom
  instance finder, e.g. a chance to perform eager loading.

  Association actions now check for permission to view the association
  owner


Model Queries

  <field>_is predicates now work with belongs_to associations.


Hobo Rapid

  rapid.dryml split up into rapid.dryml, rapid_pages.dryml
  rapid_editing.dryml and rapid_navigation.dryml

  New set of tags for creating navigation bars.

  <no_break> tag replaces spaces with &nbsp; in entire content.

  <edit> tag customisation - for form fields (i.e. new records), will
  delegate to one of:

      has_many_field
      belongs_to_field

      string_field
      textarea_field
      password_field
      html_field

      boolean_field

      date_field
      datetime_field

      integer_field
      float_field

    Redfine these to customise forms throughout the app.

    Similarly, editor fields (i.e. ajax fields for existing records)
    use:

      has_many_editor
      belongs_to_editor
      
      string_editor
      textarea_editor
      password_editor
      html_editor

      boolean_editor

      datetime_editor
      date_editor

      integer_editor
      float_editor

    Redefine these to customise ajax editors throughout the app.

    Note has_many_field and has_many_editor are just placeholders,
    they are not implemented.

  <update_button> supports a params attribute, to send extra params
  along with the HTTP PUT.

  <delete_button> now supports part updates and use of
  Hobo.removeButton together. (i.e. you can have the fade effect and
  also have other parts updated)

  <object_form> does not create a hidden field for the STI 'type' field.


New feature - Composite models

Experimental new feature - mapping tags

New feature - Predicate dispatch modules 


=== Release 0.4.3 ===

Front-controller now filters parameter logging so that passwords are
not logged.

Check if a controller is a Hobo model-controller before installing
Hobo routes.

DRYML

  Can now use obj= and attr= on the same tag, so you can e.g.

    <edit obj="#@this" attr="name"/>

  (The alternative, <edit obj="@this.name"> would not work as
  <edit> needs this_field which would be nil)

  Shorthand obj="page" for obj="#@this"

Various fixes and enhancements to the permission system. Things are somewhat
experimental and subject to change!

Core tags/helpers

  `viewable` method filters a collection down to objects that are
  viewable.


Hobo Rapid:

  <new_in_collection_page> now includes belongs_to associations in the
  form.

  Cleanup of form field / editor tags

  <ul_for> and <table_for> now skip non-viewable objects

  Fix: even/odd cycle in table_for and ul_for was broken with nested lists/tables.

  Page navigation enhanced to allow URL query parameters to be
  maintained from page to page.

  <show_collection_page> now only includes a "New Whatever" link if
  the collection is a "simple" has_many collection (no conditions, not
  :through)

  <object_link> now has a view attribute to link to alternate views of
  the object (see below: alternate show pages)

  <object_table>

    Now allows additional rows to be added by giving a tag-body.

    skip_fields attribute to remove fields from the table

  Better support for confirmation dialogues in <delete_button>


Tabla theme:

  Increased width to 800px;

  Small style enhancements


Hobo Module

  Fix to dom_id for objects in an array that is not an AR association
  (e.g. an array returned by find(:all))


Support for alternative "show" pages. E.g. to add a "profile" page to a User, add

    show_method :profile

  To the UsersController and create
  app/views/people/profile.dryml. You also get a named route
  "user_profile" (e.g. you can call user_profile_url(fred) )

  (Using Hobo Rapid you can link to these with <object_link view="profile"/>)

Fix to template lookup for association pages (e.g. posts/12/comments
and posts/12/comments/new)

Support for permission class methods (experimental). If you can define
permission without access to the object state, you can now do so on
the class:

  def self.viewable_by(viewer, field)
    false
  end

  This helps Hobo in places where there is no object. e.g. in deciding
  whether or not to present a "New Whatsit" link

Fix: pagination was broken on index pages with data-filters.


Hobo::ModelController

  Enhanced to allow updating of date and datetime fields. Dates and
  date-times can be provided either as strings (Hobo will use Chronic
  for parsing if it's installed) or hashes with :year, :month, :day
  etc. keys (as used by the select_date helper).

  find_by_data_filter renamed to find_with_data_filter and now does a
  non-filtered find if no filters were given in the request.

  Added count_with_data_filter

  Fixes to checking create permission when the post parameters
  contains related sub-objects.

  Access to the new page is forbidden if the current user does not
  have create permission.


Hobo::Model

  New model queries <field>_starts and <field>_ends

  The <field>_is query will now use an "IS NULL" query if you pass
  nil.

  Added support for counts with queries, e.g:

    User.count { name_starts 't' }

  Calling `new` on a has_many association (e.g. post.comments.new) has
  enhanced behaviour for new records (those not in the db). Hobo will
  try to set up the reciprocal belongs_to association on the created
  object. This is needed by the permission system when testing
  can_create?

  #reverse_reflection will attempt to find the reciprocal belongs_to
  association from a has_many association.


Ajax mechanism

  Fix when using multiple instances of the same part on the same page
  (i.e. when a part_id attribute appears in a loop).

  Fix when the this_field for the part context is an array index.


Chronic fix to handle dates like "11th Jan" (it can handle "Jan 11th"
and "11 Jan" but not "11th Jan")


New feature - Integration testing DSL. Adds an easy to use DSL for
integration tests.

Fix: search page in IE



=== Release 0.4.2 ===

Fix in permission system



=== Release 0.4.1 ===

New feature: "web-methods" -- RPC style actions in model-controllers. Including
support for ajax responses.

New named route "home" to FrontController#index

Hobo Rapid:

  Renamed <object_small> to <object_card>

  Added support for ajax responses to web-methods

  Removed <possessive> (too app specific)

  <object_link> now passes extra options to the generated <a> tag
  (e.g. class, id)

  Extra options to <edit> are now passed on to the delegate.

  Naming of edit controls reworked. <editor> is an ajax editor,
  <form_field> is a non-ajax form field, <edit> chooses automatically
  between the two. Other tags renamed too -
  e.g. <in_place_edit_for_boolean> renamed to
  <boolean_checkbox_editor>

  Support for datetime and date selects in form fields (not editors)

  Added autosubmit option to autocompleters - submits the form as soon
  as an option is selected.

  Added confirm option to ajax_updater (wraps call in a JS confirm
  dialogue)

  More data types supported by <editor> (formerly in_place_edit)

  New tag <belongs_to_editor>. Currently just delegates to
  <belongs_to_menu_editor> but is intended to switch to an
  autocompleter if there are too many options for a menu.

  New css classes create_button, update_button, delete_button added to
  button tags.

  Image attribute for delete_button for <input type="image">
  buttons. Needs implementing on the other buttons (or maybe we should
  be using css styling only!)

  New tag: <remote_method_button>

  <object_form> updated to only add hidden tags for fields that don't
  appear in the form.

hobo_rapid.js

  Fix: in-place-edit controls were displaying the JavaScript source of
  an alert message after a validation error.

  Support for ajax responses to RPC actions.

  Fix in Hobo.ajaxRequest when no `method` option was given.

  Hobo.applyEvents can now be given an element or a DOM ID.

  Hobo.removeButton: changed duration of Fade effect

  Fix in objectElementFor

  Re-enabled applyEvents in Hobo.updateElement


Tabla theme

  Various CSS refinements

  Added account_nav attribute to <page>

  Added class attribute to page - applied to body tag

  Disable account nav if no `login_url` route exists


hobo_user_model generator

  Migration

    Changed `login` column to `username`.

    Changed to use Hobo migration syntax

  Model: Uses new `set_login_attr`


Plugin initialiser (init.rb)

  Fixed problem with ordering of requires

  Eliminated code to load all models at startup (now done on demand in Hobo module)
  This reduces the footprint of Hobo, e.g. for apps that want only DRYML.


ActiveRecord extensions

  Added HasManyAssociation#new_without_appending. Creates a model with
  the correct belongs_to association but doesn't add it to the
  array. Needed for the permission system.

  Added #member_class to HasManyAssociation and
  HasManyThroughAssociation - convenience method for
  proxy_reflection.klass


General Ruby extensions

  Renamed is_in? to in? to conform with ruby-extensions project.

  Added Module#inheriting_attr_accessor. Creates an attribute accessor
  that looks in the superclass if the attribute does not exist on
  self. Should be used on classes (e.g. inside class << self)


User Authentication

  The user model can now override the class-method
  `password_validations` to customise those.

  Virtual fields `password` and `password_confirmation` now declared
  with field type :password. Hobo Rapid will now generate
  password-edit fields for these.

  Column used for the user-name is now declared by the user-model
  class, e.g.

    class User; set_login_attr :email; end

  Extracted acts_as_authenticated controller extensions into
  Hobo::AuthenticationSupport (was in Hobo::Controller)

  Hobo will manage a last_login_at datetime if such a column exists on
  the user model.


Site-wide search

  Added message when no results found

  Remove objects from results that are not viewable by the current_user


Hobo Controller

  Fix: render_tags - hoboParts JavaScript was rendered multiple times

  Ajax mechanism updated to support RPC actions.


Core tags & DRYML helpers

  Fix: per-request cache of current_user was not working

  Fix: can_update? was broken

  Fix: can_view_this? handles non-ActiveRecord objects better

  can_view_this? delegates to can_view if this_parent or this_field
  is null (previously an error).

  Fix: tag_for_object was broken

  <show> supports more field types

  <repeat> now sets the model_id attribute on the repeated element.

  new conditions <unless_blank>, <unless_empty>, <if_can_edit>

  add_classes split into two methods, one that modifies the hash
  (add_classes!) and one that generates a new one (add_classes)

  Made the new object optional on can_update

  Added a style attribute to <human_type> can be any string method,
  e.g. pluralize, downcase etc.


DRYML

  Form fields that appear within a DRYML form context are now tracked,
  so that hidden fields can be automatically added for just those
  fields that do not appear in the form.

  Renamed instance variable to current context to @_this. Was clashing
  with @this page context.

  Fix: this_type was failing to default to this.class when using the
  obj="" attribute

  Renamed method _part_context_js to part_context_js


Model Extensions (hobo_model)

  Renamed set_fields_types to set_field_type

  Added set_search_columns declaration as a shorthand alternative to
  defining class method search_columns. e.g.

    class Foo < ActiveRecord::Base
      hobo_model
      set_search_columns :content, :notes
    end

  An id_name with the :underscore option no longer returns the name
  with underscores by default. By default you get the name as it is in
  the DB, if you call id_name(true) you get it with underscores
  instead of spaces (e.g. for use in URLs).

  Added Hobo::Model.set_default_order e.g.

    class User < ActiveRecord::Base
      set_default_order "name"
    end 

    To use: User.find(:all, :order => :default). Default order is used
    by the hobo_model_controller

Model Controller

  Fix: show-collection action (e.g. post/12/comments) now uniquifies
  the collection if the :uniq option was given on the has_many
  declaration.

  hobo_render now allows the template to be looked for in other
  classes (e.g. in app/views/other_class)

  Added web_method declaration for RPC-style actions. e.g.

    class Users < ApplicationController
      web_method :reset_password
      def reset_password
        new_pw = @this.reset_password
        hobo_ajax_response(@this, :password => new_pw)
      end
    end

  show action now calls permission_denied unless the current user can
  view the object.

  Added customisation hooks create_response, update_response,
  destroy_response. And for invalid records: invalid_create_response,
  and invalid_update_response. The default response will only happen
  if these methods don't do a render or a redirect.

  Added before filter to prepare for a web_method

  Template lookup path changed for
  collections. e.g. /posts/12/comments will now fallback on
  app/vews/comments/show_in_collection and /posts/12/comments/12 will
  fallback on app/views/comments/new_in_collection

  index action respects the model's default_order

Model Queries

  Renamed predicate in_association to is_in

  Added predicate not_in

  Added support for model-defined predicates. Any predicate not found
  will be looked up on the model class.

Hobo module

  Removed guest_user attribute

  Hobo.models now loads all model classes on demand the first time it
  is called.

  Removed parentheses from query in find_by_search (SQLite
  compatibility)

  add_routes now adds routes for web methods

  can_create? uses new_without_appending when passed a has_many
  association to check if the user is allowed to create an object in
  that collection.

  can_edit? returns false for polymorphic associations (for now!)

  can_view? can now handle AR classes (can view instances of this
  class?)  and associations (can view items in this association?)

  Added can_call? permission method for web-methods

Added Rakefile with rdoc task
