特定页面未登录rails dev

Question

when i sign in it redirects to the root page, but here in the navbar(header) if user_signed in ? 当我登录时，它会重定向到根页面，但是如果user_signed在这里，则在导航栏（标题）中？ function is not executed, but in other pages lets say /browse/audi in the header it shows the username with logout, rest of the pages identifies that user has logged in except but the landing page 函数未执行，但在其他页面中，在标题中说/ browse / audi，它显示具有注销的用户名，其余页面标识用户已登录，但登录页面除外

 caches_page :index

layout 'application_slide', only: [:index]
layout 'car_model', only: [:car_model]
before_filter :authenticate_user!, only: "step2"

My controller for the root_path (ie, index) 我的root_path控制器（即索引）

def index
if user_signed_in?
  if current_user.role == "dealer"
    redirect_to dashboard_dealer_path
  else
    #@carmake = Carmake.search(params[:makename])asd
    #    @carmodel = Car.search(params[:makename])
    #@zipcode = Profile.search(params[:search])
    @makes = DivisionDefinition.order(:division_name)
    ................
    ................
    ................
    ................
    end
  end
end

My layout for index 我的索引布局

<title><%= content_for?(:title) ? yield(:title) : "Nabthat" %></title>

<%= stylesheet_link_tag    "admin" %>

<%= csrf_meta_tags %>
</head>

<body class="login-layout off-canvas hide-extras" id="common-nav" cz-shortcut-listen="true">
 <%= render "/layouts/navbar" %>
 <%# render "/layouts/flash" %>
 <div class="row">
  <div class="main-container" id="main-container">
    <div class="main-container-inner">
      <%= yield %>
    </div>
  </div>
</div>

My navbar 我的导航栏

    <% if !user_signed_in? %>
    <li>
      <%= link_to "Log in", "#nav-login-modal",:data => {"toggle" => "modal"}, class: "li-pull-right"%>  
    </li><li>
      <%= link_to "List Your Dealership", new_user_registration_path, class: "list-dealer-new nav-list-dealer"%>
    </li>
    <% else %>

For index action alone it shows the login link in navbar as if i'm not logged in but if i go to any other page it shows user name 仅对于索引操作，它会在导航栏中显示登录链接，就像我没有登录一样，但是如果我转到任何其他页面，它将显示用户名

While checking with curl for this error (diffrence b/w root and other page) 在使用curl检查此错误时（黑白/根和其他页面不同）

Answer 1

First check your user model it should be user.rb not users.rb 首先检查您的用户模型，它应该是user.rb而不是users.rb

Otherwise you can use current_user method for checking the user logged in or not 否则，您可以使用current_user方法来检查是否已登录的用户

Answer 2

It looks like the caches_page :index is caching the page before you sign in. Then when you are signed in, the cached page is returned without checking with your rails app server (so never has a chance to check if you're signed in) - nginx just returns it directly (which would explain why the response headers received by curl are so different). 看起来caches_page :index在您登录之前正在缓存页面。然后，当您登录时，将返回已缓存的页面，而无需使用Rails应用服务器进行检查（因此永远不会有机会检查您是否已登录） -nginx只是直接返回它（这将解释为什么curl收到的响应标头如此不同）。

If this is the case, you could resolve it by removing the caches_page :index . 如果是这种情况，您可以通过删除caches_page :index来解决。 If you really need to cache your index page, you can wrap however much of the index view you want in a <% cache do %> … <% end %> block (possibly not much as it looks like there's dynamic stuff happening in your index view too - eg the role check). 如果您确实需要缓存索引页，则可以将所需的大部分索引视图包装在<% cache do %> … <% end %>块中（可能不多，因为看起来好像动态内容正在发生）索引视图-例如角色检查）。 Alternatively you might want to use action caching or the new Rails 4 caching approach if you're on Rails 4. 另外，如果您使用的是Rails 4，则可能要使用动作缓存或新的Rails 4缓存方法。
