Module: ActiveResource::CustomMethods

ActiveSupport::Concern

Overview

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'}]
