Facebooker2

Provides rails helpers for interfacing with Facebook's OpenGraph Javascript API.

Requires the mogli gem.

Example

0- Prerequisite: You need a facebook app. Have your API Key, Application Secret, and Application ID handy.

1- Install facebooker2 as a plugin in your rails app.

2- Create config/facebooker.yml with the appropriate environment.

production:
  app_id: <your application id>
  secret: <your application secret>
  api_key: <your application key>

3- Create config/initializers/facebooker2.rb and place the following line in it

Facebooker2.load_facebooker_yaml

4- Add the following line to your app/controllers/application_controller.rb (add it right after the line class ApplicationController < ActionController::Base so as to add the Facebooker2 instance methods to the Application controller)

include Facebooker2::Rails::Controller

5- Update your rails applications to use the rails helpers. This could be in a shared login partial.

<%= fb_connect_async_js %>
<% if current_facebook_user %>
  <%= "Welcome #{current_facebook_user.first_name} #{current_facebook_user.last_name}!" %>
  or 
  <%= "Hello #{fb_name(current_facebook_user, :useyou => false)}!" # link to facebook profile %>
  <%= fb_logout_link("Logout of fb", request.url) %><br />
<% else
   # you must explicitly request permissions for facebook user fields.
   # here we instruct facebook to ask the user for permission for our website
   # to access the user's facebook email and birthday
   %>
  <%= fb_login_and_redirect('<your URL here>', :perms => 'email,user_birthday') %>
<% end %>

Facebook canvas applications

If you are building an application that runs inside a Facebook canvas, all the coming requests from Facebook to your iframe will be POST requests.

You can use the PostCanvas rack middleware to turn the Facebook POST requests back to GET requests and keep your app restful as described in this blog post. If you are using Rails 3, put this line of code inside your config.ru file :

use Rack::PostCanvas

Also, if you plan on supporting IE 6/7 and use cookie authentication, you should add a P3P header to your response in order for IE to accept the cookie :

before_filter :set_p3p_header_for_third_party_cookies

See this blog post and this forum thread for details.
