I'm using the facebooker gem which creates a variable called facebook_session in the controller scope (meaning when I can call facebook_session.user.name from the userscontroller section its okay). However when I'm rewriting the full_name function (located in my model) i can't access the facebook_session variable.

You'll have to pass the value into your model at some point, then store it if you need to access it regularly.
Models aren't allowed to pull data from controllers -- it would break things in console view, unit testing and in a few other situations.
The simplest answer is something like this:
class User
attr_accessor :facebook_name
before_create :update_full_name
def calculated_full_name
facebook_name || "not sure"
end
def update_full_name
full_name ||= calculated_full_name
end
end
class UsersController
def create
@user = User.new params[:user]
@user.facebook_name = facebook_session.user.name
@user.save
end
end

I've clarified my code so you know how to save the facebook_name to the database. Now it should work to retrieve it as you suggest.
