rails--rails/activeresource/CHANGELOG

*SVN*

* Query string support.  [untext, Jeremy Kemper]
    # GET /forums/1/topics.xml?sort=created_at
    Topic.find(:all, :forum_id => 1, :sort => 'created_at')

* Base#==, eql?, and hash methods. == returns true if its argument is identical to self or if it's an instance of the same class, is not new?, and has the same id. eql? is an alias for ==. hash delegates to id.  [Jeremy Kemper]

* Allow subclassed resources to share the site info [Rick, Jeremy Kemper]

    class BeastResource < ActiveResource::Base
      self.site = 'http://beast.caboo.se'
    end

    class Forum < BeastResource
      # taken from BeastResource
      # self.site = 'http://beast.caboo.se'
    end

    class Topic < BeastResource
      self.site += '/forums/:forum_id'
    end

* Fix issues with ActiveResource collection handling.  Closes #6291. [bmilekic]

* Use attr_accessor_with_default to dry up attribute initialization. References #6538. [Stuart Halloway]

* Add basic logging support for logging outgoing requests. [Jamis Buck]

* Add Base.delete for deleting resources without having to instantiate them first. [Jamis Buck]

* Make #save behavior mimic AR::Base#save (true on success, false on failure). [Jamis Buck]

* Add Basic HTTP Authentication to ActiveResource (closes #6305). [jonathan]

* Extracted #id_from_response as an entry point for customizing how a created resource gets its own ID.
  By default, it extracts from the Location response header.

* Optimistic locking: raise ActiveResource::ResourceConflict on 409 Conflict response. [Jeremy Kemper]

    # Example controller action
    def update
      @person.save!
    rescue ActiveRecord::StaleObjectError
      render :xml => @person.reload.to_xml, :status => '409 Conflict'
    end

* Basic validation support [Rick Olson]

  Parses the xml response of ActiveRecord::Errors#to_xml with a similar interface to ActiveRecord::Errors.  
  
    render :xml => @person.errors.to_xml, :status => '400 Validation Error'

* Deep hashes are converted into collections of resources.  [Jeremy Kemper]
    Person.new :name => 'Bob',
               :address => { :id => 1, :city => 'Portland' },
               :contacts => [{ :id => 1 }, { :id => 2 }]
  Looks for Address and Contact resources and creates them if unavailable.
  So clients can fetch a complex resource in a single request if you e.g.
    render :xml => @person.to_xml(:include => [:address, :contacts])
  in your controller action.

* Major updates [Rick Olson]

  * Add full support for find/create/update/destroy
  * Add support for specifying prefixes.
  * Allow overriding of element_name, collection_name, and primary key
  * Provide simpler HTTP mock interface for testing
  
    # rails routing code
    map.resources :posts do |post|
      post.resources :comments
    end
    
    # ActiveResources
    class Post < ActiveResource::Base
      self.site = "http://37s.sunrise.i:3000/"
    end

    class Comment < ActiveResource::Base
      self.site = "http://37s.sunrise.i:3000/posts/:post_id/"
    end
    
    @post     = Post.find 5
    @comments = Comment.find :all, :post_id => @post.id

    @comment  = Comment.new({:body => 'hello world'}, {:post_id => @post.id})
    @comment.save

* Base.site= accepts URIs. 200...400 are valid response codes. PUT and POST request bodies default to ''. [Jeremy Kemper]

* Initial checkin: object-oriented client for restful HTTP resources which follow the Rails convention. [DHH]
