ruby-on-rails - Rails 3 - CanCan 错误？ NameError(未初始化的常量 Ability::Invitation):

Question

错误:

NameError (uninitialized constant Ability::Invitation):
  app/models/ability.rb:72:in `initialize'
  app/controllers/invitations_controller.rb:12:in `new'
  app/controllers/invitations_controller.rb:12:in `current_ability'
  app/middleware/flash_session_cookie_middleware.rb:14:in `call'

在 CanCan 我有:

can :manage, Invitation

在邀请 Controller 中:

before_filter :current_ability # CanCan load_and_authorize_resource #CanCan

定义当前能力 @current_ability ||= Ability.new(current_user, nil) 结束

应用程序的 Controller :

#CanCan
def current_ability
    @current_ability ||= Ability.new(current_user, nil) # since no group
end

路线:

resources :invitations

知道为什么 CanCan 不开心吗？谢谢

Answer 1

看起来您正试图引用一个未定义的类。 app/models/invitation.rb 中是否有定义此 Invitation 类的文件？
