Thanks for the reply.

How cancan can be used for restricting the methods in controllers which has no models ?

The default setup (all I've ever done) is to configure the various roles in the ability.rb class file. If you look at the documentation or the RailsCast, that's what they start with. As far as looking up the current user to determine what role that user has, CanCan assumes you're using some authentication, which probably means looking up the user from the database, and that the authentication creates a current_user method that returns an object representing that authenticated user. CanCan doesn't get into the business of creating that current_user, though.
