Question

当我尝试访问“登录”路线（GET / users / sign_in）时，我收到以下错误...

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

以下是服务器日志中的完整错误...

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>

我唯一拥有的控制器是“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任何关系，但我也使用rails generate devise:views命令生成了视图。

为什么在我执行GET / users / sign_in时尝试访问不存在的“设计/页面”控制器和“主页”操作？当我rake routes ...

时，这不是我的路线所显示的

                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”...

<!-- 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>

UPDATE 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'} %>

并删除它可以让我的sign_in页面成功加载。为什么呢？！

Answer 1

在构造{:action => 'home', :controller => 'pages'}的URL时，Rails使用相对于控制器呈现当前视图的路径。对于登录页面，这将是“设计/会话”，因此它在devise命名空间中查找PagesController。

您可以通过添加反斜杠来修复它，以指定控制器位于根目录中，而不是在设计名称空间内。

替换：

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

用这个：

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

Answer 2

“”，：width =＆gt;“300”，：height =＆gt;“100”），root_path％＆gt;

我相信传递的link_to网址是设计范围的。您应该改为从rake路由生成的路径名。

Answer 3

我在安装Devise时遇到同样的问题，之后无法运行任何东西。但在我的情况下，我试图使用Rails指向路线页面的路线来解决它：

＆＃13;

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

＆＃13;

一切都在追赶。

Answer 4

我找到了在相对文件中控制器启动时添加反斜杠'/'的地方，其中错误将显示在相关文件中（请参阅development.log中的错误）就我而言：

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

或

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

Rails 3.1 + Devise：Devise的默认路由不起作用
