multiple inheritance for a model

Question

I want to create a multiple inheritance for a model.

in order to do that, I tried something like:

class User < ActiveRecord::Base, Devise::SessionsController

what is the way to do that correctly? I think my Syntax is not correct.

Ruby doesn't support multiple inheritance. To share functionality between models, you want to use mixins. Check out this article, particularly the section on mixins.
