Ruby on rails 筛选器链暂停为：要求\u无\u身份验证已呈现或重定向

我使用了designegem，并使用designe命令以User作为名称生成了视图

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

<% 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 %>

---

请告诉我哪里出了问题。我无法找出错误。

对于

家庭控制器

，您可能需要一个

在筛选之前跳过。在
HomeController
的顶部，
：在筛选之前跳过：不需要身份验证，仅：[：索引]

我不确定跳过所有过滤器是否是正确的解决方案。如果这对你不起作用，可能会有帮助

class HomeController < ApplicationController   
  def index

  end 
end
