Initialization

Without a token (for authorization)

client = FBGraph::Client.new(:client_id => 'client_id',:secret_id =>'secret_id')

With a token

client = FBGraph::Client.new(:client_id => 'client_id',:secret_id =>'secret_id' ,:token => token)

All methods are chainable

Examples:

client.selection.me.photos.until(Time.now.to_s).since(3.days.ago).limit(10).info client.selection.user('id').videos.offset(10).info client.search.query('q').on('users').limit(20).info

Authorization

client.authorization.authorize_url

returns the authorize url

redirect_to client.authorization.authorize_url(:redirect_uri => callback_url , :scope => 'email,user_photos,friends_photos')

client.authorization.process_callback

process the callback and returns the access token

access_token = client.authorization.process_callback(params[:code], :redirect_uri => callback_url)

Selection

Accessing objects with connection types.

All objects and their connections can be accesed

Examples:

client.selection.me.home.info! client.selection.user('id').photos.info! client.selection.photo('id').comments.info! client.selection.page('id').info!

Also you can get results of more than 1 objects

Example:

client.selection.user([id1,id2,id3]).info!
