How to integrate CanCan with multiple devise models?

Question

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

Answer 1

The current user model is passed to the Ability#initialize, so you can just check its class:

class Ability
  include CanCan::Ability

  def initialize(model)
    case model
    when Admin
      can :manage, :all
    when User
      can :create, Comment
      can :read, :all
    else
      can :read, :all
    end
  end
end
