ActiveResource::CustomMethods

A module to support custom REST methods and sub-resources, allowing you to break out of the “default” REST methods with your own custom resource requests. For example, say you use Rails to expose a REST service and configure your routes with:

   map.resources :people, :new => { :register => :post },
                          :member => { :promote => :put, :deactivate => :delete }
                          :collection => { :active => :get }

 This route set creates routes for the following HTTP requests:

   POST    /people/new/register.xml # PeopleController.register
   PUT     /people/1/promote.xml    # PeopleController.promote with :id => 1
   DELETE  /people/1/deactivate.xml # PeopleController.deactivate with :id => 1
   GET     /people/active.xml       # PeopleController.active

Using this module, Active Resource can use these custom REST methods just like the standard methods.

  class Person < ActiveResource::Base
    self.site = "http://37s.sunrise.i:3000"
  end

  Person.new(:name => 'Ryan).post(:register)  # POST /people/new/register.xml
  # => { :id => 1, :name => 'Ryan' }

  Person.find(1).put(:promote, :position => 'Manager') # PUT /people/1/promote.xml
  Person.find(1).delete(:deactivate) # DELETE /people/1/deactivate.xml

  Person.get(:active)  # GET /people/active.xml
  # => [{:id => 1, :name => 'Ryan'}, {:id => 2, :name => 'Joe'}]

Public Class Methods

delete(custom_method_name, options = {}) click to toggle source
    # File lib/active_resource/custom_methods.rb, line 68
68:         def delete(custom_method_name, options = {})
69:           # Need to jump through some hoops to retain the original class 'delete' method
70:           if custom_method_name.is_a?(Symbol)
71:             connection.delete(custom_method_collection_url(custom_method_name, options), headers)
72:           else
73:             orig_delete(custom_method_name, options)
74:           end
75:         end
Also aliased as: orig_delete
get(custom_method_name, options = {}) click to toggle source

Invokes a GET to a given custom REST method. For example:

  Person.get(:active)  # GET /people/active.xml
  # => [{:id => 1, :name => 'Ryan'}, {:id => 2, :name => 'Joe'}]

  Person.get(:active, :awesome => true)  # GET /people/active.xml?awesome=true
  # => [{:id => 1, :name => 'Ryan'}]

Note: the objects returned from this method are not automatically converted into ActiveResource::Base instances - they are ordinary Hashes. If you are expecting ActiveResource::Base instances, use the find class method with the :from option. For example:

  Person.find(:all, :from => :active)
    # File lib/active_resource/custom_methods.rb, line 56
56:         def get(custom_method_name, options = {})
57:           connection.get(custom_method_collection_url(custom_method_name, options), headers)
58:         end
orig_delete(custom_method_name, options = {}) click to toggle source
Alias for: delete
post(custom_method_name, options = {}, body = '') click to toggle source
    # File lib/active_resource/custom_methods.rb, line 60
60:         def post(custom_method_name, options = {}, body = '')
61:           connection.post(custom_method_collection_url(custom_method_name, options), body, headers)
62:         end
put(custom_method_name, options = {}, body = '') click to toggle source
    # File lib/active_resource/custom_methods.rb, line 64
64:         def put(custom_method_name, options = {}, body = '')
65:           connection.put(custom_method_collection_url(custom_method_name, options), body, headers)
66:         end
