Q:

is there omniauth code/plugin for facebook that i can put straight into my ruby on rails site?

I am making a social network on the teamtreehouse.com course in ruby on rails. 
However, on the course they do not add a 'sign in with facebook' feature.
Is there any code i can put straight in so it will work? or a plugin type thing? 
I tried to follow this course but i didn't really understand it.

A:

Here's a great RailsCast by Ryan Bates  on logging in with Facebook that should explain most everything you need.  
(Yes, you do need to get a special developer token from Facebook).
Then, pony up for the Pro subscription for $9 -- writing Rails without RailsCasts is inconceivable to me :-)
