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.json # PeopleController.register PUT /people/1/promote.json # PeopleController.promote with :id => 1 DELETE /people/1/deactivate.json # PeopleController.deactivate with :id => 1 GET /people/active.json # 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.json # => { :id => 1, :name => 'Ryan' } Person.find(1).put(:promote, :position => 'Manager') # PUT /people/1/promote.json Person.find(1).delete(:deactivate) # DELETE /people/1/deactivate.json Person.get(:active) # GET /people/active.json # => [{:id => 1, :name => 'Ryan'}, {:id => 2, :name => 'Joe'}]

This method is also aliased as
orig_delete
# File activeresource/lib/active_resource/custom_methods.rb, line 70 70: def delete(custom_method_name, options = {}) 71: # Need to jump through some hoops to retain the original class 'delete' method 72: if custom_method_name.is_a?(Symbol) 73: connection.delete(custom_method_collection_url(custom_method_name, options), headers) 74: else 75: orig_delete(custom_method_name, options) 76: end 77: end
Invokes a GET to a given custom REST method. For example:
Person.get(:active) # GET /people/active.json # => [{:id => 1, :name => 'Ryan'}, {:id => 2, :name => 'Joe'}] Person.get(:active, :awesome => true) # GET /people/active.json?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 activeresource/lib/active_resource/custom_methods.rb, line 56 56: def get(custom_method_name, options = {}) 57: hashified = format.decode(connection.get(custom_method_collection_url(custom_method_name, options), headers).body) 58: derooted = Formats.remove_root(hashified) 59: derooted.is_a?(Array) ? derooted.map { |e| Formats.remove_root(e) } : derooted 60: end
