Rails3-amf is a Rails 3 plugin that aims to do what RubyAMF did for Rails 2. It provides extensively customizable ActiveRecord serialization support, simple configuration, and allows AMF calls to any controller you choose. It uses RocketAMF for serialization, providing users with a proven AMF0/3 serializer and deserializer. Because of this, it’s also fully Ruby 1.9 compatible out of the box.
To get started with rails3-amf, all you need to do is add the following two lines to your gemfile. RocketAMF will need to be pulled from git for now, as there are several necessary updates that have been made to it to allow rails3-amf to work properly.
gem 'RocketAMF', :git => 'git://github.com/warhammerkid/rocket-amf.git' gem 'rails3-amf', :git => 'git://github.com/warhammerkid/rails3-amf.git'
Then, make sure that your controller will respond to amf by adding :amf
to your respond_to, and you should be all ready to go with an AMF gateway available at your-site.com/amf. ActiveRecord objects will automatically be serialized with all attributes and no relations, but that can be easilly adjusted through the standard serialization options for ActiveRecord and ActiveModel serialization.
class UserController < ApplicationController respond_to :html, :amf def getUser @user = User.first respond_with(@user) do |format| format.amf { render :amf => @user.to_amf(:except => [:updated_at, :created_at], :include => [:courses]) } end end end
Rails3-amf has several configuration options. The gateway path, which defaults to “/amf” can be changed to anything you choose. You can map method call arguments by index to named params in your controllers. Finally, there’s the ability to specify flash->ruby class name mappings.
Example:
config.rails3amf.gateway_path = "/rubyamf/gateway" config.rails3amf.class_mapping do |m| m.map :as => 'Test::User', :ruby => 'User' m.map :as => 'vo.Course', :ruby => 'Course' end config.rails3amf.map_params :controller => 'UserController', :action => 'getUser', :params => [:session_id]
