练习一个 WEB/API 应用，试用 Pandit 做权限管理，请问为什么/controller/api/v1/users_controller.rb 和/controller/users_controller.rb 都指向同一个/policies/user_policy.rb 文件？怎么才能设置指向不同的文件？谢谢。 /controller/api/v1/base_controller.rb

class Api::V1:BaseController < ApplicationController
  include Pundit
......
end

/controller/api/v1/users_controller.rb

class Api::V1:UsersController < BaseController
  def index
    @users = User.all
    authorize @users
  end
end

/controller/application_controller.rb

class ApplicationController < ApplicationController::Base
  include Pundit
......
end

/controller/users_controller.rb

class UsersController < ApplicationController
  def index
    @users = User.all
    authorize @users
  end
end

/policies/user_policy.rb

class UserPolicy < ApplicationPolicy
  class Scope <Scope
    def resolve
  end
  def index? true end
end
