Question

我正在使用带有rails的设计。我已经在设计中生成了用户模型，我没有用户控制器和家庭控制器。我的根页是devise/sessions#new。

我的根路径

 devise_scope :user do
   root :to => "users/sessions#new"
 end
 devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks", :registrations => "users/registrations" }

当我运行localhost：3000时，我收到以下错误。

Filter chain halted as :require_no_authentication rendered or redirected. 

Started GET "/" for 127.0.0.1 at 2014-02-19 10:07:46 +0530

Filter chain halted as :require_no_authentication rendered or redirected

我在互联网上找到的解决方案是在会话控制器prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]中添加它。我怀疑的是如何访问会话控制器。它不是在控制器中生成的，它是内置模块，还是有其他方法可以解决这个问题。

应用/控制器/用户/ session_controller.rb

class Users::SessionsController < Devise::SessionsController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
end

Answer 1

您可以像这样覆盖会话控制器：

<强> route.rb

devise_scope :user do
  root to: "users/sessions#new"
end

应用/控制器/用户/ sessions_controller.rb

class Users::SessionsController < Devise::SessionsController prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ] end

使用设计gem过滤链停止错误
