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
user = FbGraph::User.me(ACCESS_TOKEN)
user = FbGraph::User.fetch('matake')
user.name # => 'Nov Matake'
user.picture # => 'https://graph.facebook.com/matake/picture'
# fb_graph doesn't access to Graph API until you call "fetch"
user = FbGraph::User.new('matake', :access_token => YOUR_ACCESS_TOKEN)
user.identifier # => "matake"
user.name # => nil
user.link # => nil
user = user.fetch
user.name # => "Nov Matake"
user.description # => "http://www.facebook.com/matake"
page = FbGraph::Page.fetch('smartfmteam')
page.name # => 'smart.fm'
page.picture # => 'https://graph.facebook.com/smart.fm/picture'
:
# Public connections
user = FbGraph::User.fetch('matake')
user.feed
user.posts
user.friends
user.tagged
user.family
:
# Private connections requires "access_token"
FbGraph::User.new('matake').friends # => raise FbGraph::Unauthorized
user = FbGraph::User.fetch('matake', :access_token => ACCESS_TOKEN)
user.albums
user.events
user.friends
user.likes
:
# "home" connection is only available for "me"
me = User.new('me', :access_token => ACCESS_TOKEN)
me.home
:
By default, FbGraph will only return the default fields. In order to get a non-default field, you have to supply the connect with an options hash specifying the field. An example for events:
user.events({:fields => "owner,name,description,picture"}) # { and } optional
An overview of which fields you can include in the graph API can be found at developers.facebook.com/docs/reference/api/, which has a description of the specific objects fields in the sidebar under “Objects”.
# all objects FbGraph::Searchable.search("FbGraph") # => Array of Hash # specify type FbGraph::Page.search("FbGraph") # => Array of FbGraph::Page FbGraph::User.search("matake", :access_token => ACCESS_TOKEN) # => Array of FbGraph::User
# collection user = FbGraph::User.new('matake', :access_token => ACCESS_TOKEN) likes = user.likes # => Array of FbGraph::Like likes.next # => Array of FbGraph::Like (next page) likes.previous # => Array of FbGraph::Like (previous page) likes.collection.next # => Hash for pagination options (ex. {"limit"=>"25", "until"=>"2010-08-08T03:17:21+0000"}) likes.collection.previous # => Hash for pagination options (ex. {"limit"=>"25", "since"=>"2010-08-08T06:28:20+0000"}) user.likes(likes.collection.next) # => same with likes.next user.likes(likes.collection.previous) # => same with likes.previous # search results results = FbGraph::Page.search("FbGraph") # => Array of FbGraph::Page results.next # => Array of FbGraph::Page (next page) results.previous # => Array of FbGraph::Page (next page) results.klass # => FbGraph::Page results.collection.next # => Hash for pagination options (ex. {"limit"=>"25", "until"=>"2010-08-08T03:17:21+0000"}) results.collection.previous # => Hash for pagination options (ex. {"limit"=>"25", "since"=>"2010-08-08T06:28:20+0000"}) results.klass.search(results.query, results.collection.next) # => same with results.next results.klass.search(results.query, results.collection.previous) # => same with results.previous

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! :client_auth_body # => 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.exchange_token! 'short-life-access-token' 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.
