Example of using Facebooker

facebooker_example.rb

# Unique Facebook ID of this user
facebook_id = current_facebook_user.id
# The OAuth token, this is how you access the user at a later point
token = current_facebook_client.access_token
# OAuth token expiration.  Save this off, you'll need this to recreate 
# the user later
expiration = current_facebook_client.expiration.to_i

name = current_facebook_user.name
# Gets an array of Mogil::Users 
friends = current_facebook_user.friends 

# Save facebook_id, token, and expiration to the database

# at some later point....
# load access token and expiration from database
client = Mogli::Client.new(access_token, expiration)
# User will be able to do everything that you can from the above steps,
# assuming that the access token is still valid (usually if the user 
# has given your app the offline_access permission)
user = Mogli::User.find(facebook_id, client)
