当我尝试访问“登录”路由 (GET /users/sign_in) 时出现以下错误...

No route matches {:action=>"home", :controller=>"devise/pages"}

这是来自服务器日志的完整错误...

Started GET "/users/sign_in" for 127.0.0.1 at 2012-06-05 00:51:54 -0700
  Processing by Devise::SessionsController#new as HTML
Rendered devise/shared/_links.erb (2.9ms)
Rendered devise/sessions/new.html.erb within layouts/application (33.5ms)
Rendered pages/_header.html.erb (75.9ms)
Completed 500 Internal Server Error in 349ms

ActionView::Template::Error (No route matches {:action=>"home", :controller=>"devise/pages"}):

这是我的应用程序/布局的主体......

<!-- BEGIN body -->
<body class="top">

    <!-- BEGIN .container -->
    <div class="container">

        <%= render 'pages/header' %>
        <%= render 'pages/menu' %>

        <p class="notice"><%= notice %></p>
        <p class="alert"><%= alert %></p>

        <%= yield %>

    <!-- END .container -->
    </div>

    <%= render 'pages/footer' %>

</body>

我拥有的唯一控制器是“页面”控制器。另外，这是我的 route.rb 文件...

MyApp::Application.routes.draw do

  devise_for :users

  match '/contact', :to => 'pages#contact'
  match '/news', :to => 'pages#news'
  match '/home', :to => 'pages#home'
  match '/features', :to => 'pages#features'

  root :to => 'pages#home'

end

我不知道它是否与它有关，但我也使用rails generate devise:views命令生成了视图。

当我执行 GET /users/sign_in 时，为什么它试图访问不存在的“设计/页面”控制器和“主页”操作？当我这样做时，这不是我的路线所显示的rake routes......

new_user_session GET    /users/sign_in(.:format)       {:action=>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)       {:action=>"create", :controller=>"devise/sessions"}
    destroy_user_session DELETE /users/sign_out(.:format)      {:action=>"destroy", :controller=>"devise/sessions"}

       new_user_password GET    /users/password/new(.:format)  {:action=>"new", :controller=>"devise/passwords"}
      edit_user_password GET    /users/password/edit(.:format) {:action=>"edit", :controller=>"devise/passwords"}
                         PUT    /users/password(.:format)      {:action=>"update", :controller=>"devise/passwords"}

                         DELETE /users(.:format)               {:action=>"destroy", :controller=>"devise/registrations"}
                    root        /                              {:controller=>"pages", :action=>"home"}
                 contact        /contact(.:format)             {:controller=>"pages", :action=>"contact"}
                    news        /news(.:format)                {:controller=>"pages", :action=>"news"}
                    home        /home(.:format)                {:controller=>"pages", :action=>"home"}
                features        /features(.:format)            {:controller=>"pages", :action=>"features"}

非常感谢您的智慧！

编辑按要求添加“页面/菜单”部分......

<!-- BEGIN .menu-primary -->
    <div class="menu-primary">
        <table>
            <tr>
                <td class="menu">
                    <ul>
                        <li>
                            <a href="/news">News</a>
                        </li>
                        <li>
                            <a href="/features"><span>Shop Products</span></a>
                            <ul>
                                <li><a href="/features">Features</a></li>
                            </ul>
                        </li>
                        <li><a href="#"><span>Shop Parts</span></a><ul><li><a href="#">Controls (Coming Soon)</a></li><li><a href="#">Monitors (Coming Soon)</a></li><li><a href="#">Artwork (Coming Soon)</a></li><li><a href="#">Accessories (Coming Soon)</a></li></ul></li>
                        <li><a href="/contact">Contact Us</a></li>
                    </ul>
                </td>
            </tr>
        </table>
    <!-- END .menu-primary -->
    </div>

更新在我的标题模板中，我有......

<%= link_to image_tag("mylogo.png", :alt=>"", :width=>"300", :height=>"100"), {:action => 'home', :controller => 'pages'} %>

删除它可以让我的登录页面成功加载。为什么？！

在为 构建 URL 时{:action => 'home', :controller => 'pages'}，Rails 使用相对于呈现当前视图的控制器的路径。对于登录页面，这将是“设计/会话”，因此它会在命名空间中查找 PagesController devise。

您可以通过添加反斜杠来指定控制器在根目录中，而不是在设计命名空间中来修复它。

代替：

{:action => 'home', :controller => 'pages'}

有了这个： 

{:action => 'home', :controller => '/pages'}

"", :width=>"300", :height=>"100"), root_path %>

我相信传递的 link_to url 的范围是设计的。您应该改用从 rake 路由生成的路径名。

我在安装 Devise 时遇到了同样的问题，之后无法运行任何东西。但就我而言，我尝试使用 Rails 在路由页面上指向的路由来解决它：

<%= link_to 'Home', {:controller => 'frontpages', :action => 'services'}, class: 'footer-nav-link' %>
  
To:
  
<%= link_to 'Services', frontpages_services_path, class: 'footer-nav-link' %>

一切都在追赶。

我找到了在相对文件的控制器开头添加反斜杠“/”的地方，其中错误将显示在相关文件中（参见错误，即 development.log）在我的情况下：

= link_to "About", :controller => "/pages", :action => "about"

或者 

= link_to "Home", :controller => "/pages", :action => "home"
