You need to define your user model with the following columns:
- identifier
- FB user id (t.string :identifier, :limit => 20)
- access_token
- OAuth Access token (t.string :access_token)
Include our FbGraphRails::FbModel into your user model:
class FacebookUser < ActiveRecord::Base
include FbGraphRails::FbModel
...
end
and include into your controller our authentication filter:
class QuizzesController < ApplicationController
fb_authenticate
....
end
