过滤器链因 :require_no_authentication 呈现或重定向而停止答案

【问题描述】：

我使用了 devise gem 并使用以 User 为名称的 devise 命令生成了视图。

为了在整个应用程序中显示登录/注销链接，我将其添加到我的 layouts/application.html.erb

<% if user_session.present? %>
  <%= link_to "logout", destroy_user_session_path, :method => 'delete' %>
<% else %>
  <%= link_to "Login", new_user_session_path, :method => 'get' %>
<% end %>
<%= yield %>

这是只有索引操作的主控制器：

class HomeController < ApplicationController   
  def index

  end 
end

根被定义为指向home#index。

当我启动应用程序时，它显示登录链接，点击该链接后，我收到以下错误：

Started GET "/users/sign_in" for ::1 at 2015-11-23 23:15:32 +0530
Processing by Devise::SessionsController#new as HTML
  User Load (0.3ms)  SELECT  `users`.* FROM `users` WHERE `users`.`id` = 1  ORDER BY `users`.`id` ASC LIMIT 1

Completed 200 OK in 8ms (Views: 6.7ms | ActiveRecord: 0.4ms)

请建议我哪里出错了。我无法找出错误。

【解决方案1】：

对于HomeController，您可能需要skip_before_filter。在顶部HomeController、:skip_before_filter :require_no_authentication, only: [:index]

我不确定一起跳过过滤器是正确的解决方案。如果这对您不起作用，this post 可能会有所帮助。
