Hi,

 I recently finished a VERY simple implementation of DA on Rails with the OAuth gem. I figured some people might be interested in some working code. To test, go to http://URL_TO_RAILS_APP/myspace and it will redirect you to authorize. Then, it will print the raw JSON to the screen. Note that the OAuth library does not currently support oauth_callback, and we must manually append it. The code below will run fine with the default routes.

myspace_controller.rb

require 'oauth/consumer'

class MyspaceController < ApplicationController
    def index
        @consumer = OAuth::Consumer.new("CONSUMER_KEY","CONSUMER_SECRET", {
                :http_method=>"get",
                :site=>"http://api.myspace.com",
                :request_token_path=>"/request_token",
                :access_token_path=>"/access_token",
                :authorize_path=>"/authorize"
        })
        @request_token=@consumer.get_request_token
        session[:request_token]=@request_token
        redirect_to @request_token.authorize_url+"&oauth_callback="+CGI.escape("http://URL_TO_RAILS_APP/myspace/callback")
    end
    
  def callback
        @request_token=session[:request_token]
        @access_token=@request_token.get_access_token
        @myspace_person=@access_token.get "/v2/people/@me/@self?format=json"
        @myspace_friends=@access_token.get "/v2/people/@me/@friends?format=json"
  end
end 

callback.html.erb

<h1>Myspace#callback</h1>
<p><%= @myspace_person.body %></p>
<p><%= @myspace_friends.body %></p>
<p><%= @myspace_activities.body %></p>


 Thanks! This is most helpful. To make the authorization persistent, how would you save @access_token? Would you just save the access token's string and secret?

I am not sure that the access token is valid outside one given session... The documentation mentions a "session based Access Token", and tinkering also leads me to believe that it is only valid for the session.

 This begs the question - what can you do with data that is only retrievable one session and (for the most part) cannot be stored on the server? It seems very limiting.

 Hi Scott,

 Thanks for the great example!  got this up and running in no time.  For other developers: if you run into the error:

instance of OAuth::Consumer needs to have method `marshal_load'
