Devise Helpers(authenticate_user!,current_user,user_signed_in？)未初始化

我正在设置设计,需要能够使用设计助手.当我添加 before_filter :authenticate_user!到应用程序控制器时,我收到以下错误undefined method 'authenticate_user!' for #

它不是直接存在于我的家庭控制器中,而是从应用程序控制器继承,如果skip_before_filter :authenticate_user!我在家中(或任何控制器)使用并尝试访问该页面,我会收到以下错误.

undefined method `user_signed_in?' for #<#

它打破了调用它的layouts/application.html.erb文件中的行.任何助手都会发生同样的事情.但是,当我加载rails控制台并输入$LOAD_PATH.dup包含的输出时,它看起来好像根本没有被加载

 "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/lib", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/controllers", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/helpers", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/mailers" 

所以看起来它们确实应该由rails加载.

这是我的应用程序控制器

class ApplicationController

helper:all
#include all helper,protect_from_forgery一直
包括ActionView :: Helpers :: NumberHelper
before_filter:authenticate_user!

结束

我在安装设备后重新启动了服务器,并且多次尝试不同的尝试来解决问题.如果需要更多文件或信息,请告诉我.非常感谢你提前.

编辑:我的user.rb文件被要求显示我确实安装了devise

class User < ActiveRecord::Base

  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :encryptable, :encryptor => :restful_authentication_sha1  

  # Setup accessible (or protected) attributes for your model  
  attr_accessible :email, :password, :password_confirmation, :remember_me  

end

编辑:整个错误消息

HomeController中的NoMethodError #index

未定义的方法`authenticate_user!' 对于#'

这是完整的痕迹

一定要加入devise_for :user你的routes.rb

这个答案适用于我的API应用程序.我必须在根级别添加`devise_for:user`以便定义`authenticate_user!`方法,即使我在`api/v1`命名空间中只需要`devise_for:user`.

给这个答案一个大绿色检查!

只需重启rails服务器即可.

"请注意,如果你已经启动它,你应该在这里重新启动你的应用程序.否则你会遇到一些奇怪的错误,例如用户无法登录并且路由助手未定义." [入门说明]

[编辑]更详细的答案:

请验证另外两件事:您的HomeController应该继承自Devise :: Controllers :: Helpers.而route.rb中的devise指令(在Helpers中生成缺少的方法)应该有扩展的Devise.@@ mappings.以下代码可以检查:

class ApplicationController ...
  ...
  before_filter do
    fail "bad ancestor" unless self.kind_of?(Devise::Controllers::Helpers)
    fail "no mapping" unless Devise.class_variable_get(:@@mappings).[:user]
    authenticate_user!
  end
end

要在工作轨道应用程序中引入类似问题,必须禁用config/initializers/devise.rb和config/routes.rb设计条目,并且必须重新启动rails.除非重新启动rails,否则重新启用代码将无法解决问题.
