How to integrate CanCan with multiple devise models?

Question

How would I go about defining abilities for several devise models?

Answer 1

This worked for me -

class Ability
  include CanCan::Ability

  def initialize(user)
    if user.is_a?(Admin)
      can :manage, :all
    elsif user.is_a?(User)
      can :create, Comment
      can :read, :all
    else
      can :read, :all
    end
  end
end
