Now FbGraph supports all objects listed here: developers.facebook.com/docs/reference/api/ Almost all connections for each object are also supported. (“attachments” and “shares” connections of message object are not supported yet)
You can also play with a Rails sample app here. fbgraphsample.heroku.com/
See GitHub wiki for more examples. github.com/nov/fb_graph/wiki

Both Facebook JavaScript SDK and normal OAuth2 flow is supported. Below I show simple sample code. You can also see github.com/nov/fb_graph_sample for more details Rails3 sample application.
In addition, if you are migrating an application that uses old-style session keys you can exchange the keys for access tokens. See more here: developers.facebook.com/docs/authentication/fb_sig/
fb_auth = FbGraph::Auth.new(YOUR_APP_ID, YOUR_APPLICATION_SECRET) fb_auth.client # => Rack::OAuth2::Client # get Facebook's auth cookie in advance using their JS SDK fb_auth.from_cookie(cookies) fb_auth.access_token # => Rack::OAuth2::AccessToken fb_auth.user # => FbGraph::User (only basic attributes) fb_auth.user.fetch # => fetch more details
# setup client client = fb_auth.client client.redirect_uri = "http://your.client.com/facebook/callback" # redirect user to facebook redirect_to client.authorization_uri( :scope => [:email, :read_stream, :offline_access] ) # in callback client.authorization_code = params[:code] access_token = client.access_token! # => Rack::OAuth2::AccessToken FbGraph::User.me(access_token).fetch # => FbGraph::User
# setup client fb_auth = FbGraph::Auth.new(YOUR_APP_ID, YOUR_APPLICATION_SECRET) fb_auth.from_session_key('my-old-session-key') fb_auth.access_token # => Rack::OAuth2::AccessToken
app = FbGraph::Application.new(YOUR_APP_ID, :secret => YOUR_APPLICATION_SECRET) app.insights # => Array of FbGraph::Insight

-
Fork the project.
-
Make your feature addition or bug fix.
-
Add tests for it. This is important so I don’t break it in a future version unintentionally.
-
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
-
Send me a pull request. Bonus points for topic branches.
