嗨， 我需要你的康康帮助。Rails Cancan NameError - 未初始化的常量
我有这个CONTROLER：
类RegistrationsController <设计:: RegistrationsController
我需要的，因为我不得不重写的一些方法。
我需要控制对此控制器的访问权限，因为只有管理员可以添加新用户。
如何使用load_and_authorize_resource？
我ability.rb文件是： 类能力 包括惭惭::能力
DEF初始化（用户，controller_namespace） 用户|| = Usuario.new
case controller_namespace
when "Administrator"
if user.rol == 1
can :manage, Faq
can :manage, Tip
can :manage, Administrator::HomeTratamientoController
end
if user.rol == 2
can :manage, :admin_vacunas
can :manage, Registration
end
when "paciente"
if user.rol == 3
can :manage, Paciente::HomeController
end
else
can :read, :all
end
end
该模型是usuario.rb
我没有问题，当把rol为1，但是当为2，我放线：
load_and_authorize_resource
在注册控制器时我所说的新的行动由管理员联系，以添加新用户，告诉我后续的错误：

有些身体可以帮我吗？
你确实有'Registration'模型吗？ – coorasse
谢谢你的回答。这个模型是Usuario.rb，RegistrationsController是一个来自devise的控制器，我读过如果我在ability.rb文件中使用： 可以：管理，管理员:: RegistrationsController 和控制器中： load_and_authorize_resource类：“RegistrationsController”应该工作，但不是 – josedes
