I'm not sure this is doing what you think it is. If you have a boolean column on your model called is_admin, then Rails will define an is_admin? method for you (it actually does this for all columns, not just the booleans). When you redefine your is_admin? method to self.is_admin?, you are moving it up to become a class method, which means that when you call @user.is_admin? you are getting the Rails-added version of the method. If you called User.is_admin? you would get an error, or nothing, because the method as you wrote it here doesn't make a lot of sense. (As an instance method, it will always return true, assuming that all of your users have a non-empty username. As a class method, assuming you called it, I think you would get an error saying that self.username is undefined.)
