Answer 1

class ApplicationHelper
  def current_auth_resource
    if admin_signed_in?
      current_admin
    else
      current_user
    end
  end

  def current_ability
      @current_ability or @current_ability = Ability.new(current_auth_resource)
  end
end

class ApplicationController
  include ApplicationHelper
end

class Ability
  include CanCan::Ability

  def initialize(user)      
    if user.is_a?(Admin)
      # add admin permissions only
    elsif user.is_a?(User)
      # add user permissions only
    else
      # add guest permissions only
    end
  end
end

Answer 2

您需要在您的ability.rb 文件中指定某些用户可以操作和执行操作的模型。

class Ability
  include CanCan::Ability

  # usual setup
  def initialize(user)
    user ||= User.new

    if user.has_role? :admin
      can :manage, :all
    end

    if user.has_role? :less_important_role
      can [:read, :update], Model1
      can :manage, Model2
    end
  end
end
