is it always need Authentication.rb in lib when combined with authlogic

[bopbi]

why always shows

undefined local variable or method `current_user'

when i am defined ability and using authlogic

[molte]

You need to define the following methods in your ApplicationController:

def current_user_session
  return @current_user_session if defined?(@current_user_session)
  @current_user_session = UserSession.find
end

def current_user
  return @current_user if defined?(@current_user)
  @current_user = current_user_session && current_user_session.user
end

ok. thanks

it should be documented in the cancan README

[molte]

The README already states that a current_user method is required, but CanCan works with any authentication system and the method might therefore look different.

Actually, as far as I remember the methods is documented in the authlogic README.

Right, as molte stated, the current_user method is mentioned in the README and should be defined. How one defines this is up to them and dependent on their authentication solution.
