Question

我有：
Rails 3.0.9
设计1.5.3

我正在使用Devise进行用户身份验证当我处于开发模式时，一切都很完美但是当我尝试将Rails从开发模式切换到生产模式时，我收到一条消息：

user_controller.rb：

class User < Devise::RegistrationsController
    before_filter :authenticate_user!
end

请帮帮我。

Answer 1

检查您的Gemfile以及environment.rb第5行

中的要求

并且至少从before_filter :authenticate_user!移除user_controller ..如果您尚未登录则无法注册新用户

如果您看到https://github.com/plataformatec/devise/blob/master/app/controllers/devise/registrations_controller.rb

有

class Devise::RegistrationsController < DeviseController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
  prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy]

所以如果你添加了before_filter，你就破坏了所有的功能
