css - Redirect_to session_path 控制器并查看 RAILS DEVISE

Question

为什么这不起作用？我尝试了多种选择，例如渲染和放置，但它不想正确更改。几个想法用户？

风景：

<div id = "container">
    <div id = "smaller-container">
    <%= user_signed_in? %>
  <%= @Uchecker %>
  <% else %>
     <%= link_to "Sign Up", new_user_registration_path, :id => "SignUpText" %>
    </div>

控制器：

class PostsController < ApplicationController
  def Uchecker
    @Uchecker = redirect_to user_session_path
 end
end
