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

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>
我唯一的 Controller 是“pages” Controller 。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
我不知道它是否与此有关，但我还使用 railsgenerate devise:views 命令生成了 View 。
当我执行 GET/users/sign_in 时，为什么它会尝试访问不存在的“devise/pages” Controller 和“home”操作？当我进行rake 路线时，这不是我的路线显示的内容...
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"}
user_password POST /users/password(.:format) {:action=>"create", :controller=>"devise/passwords"}
new_user_password GET /users/password/new(.:format) {:action=>"new", :controller=>"devise/passwords"}

news /news(.:format) {:controller=>"pages", :action=>"news"}
home /home(.:format) {:controller=>"pages", :action=>"home"}
features /features(.:format) {:controller=>"pages", :action=>"features"}
提前非常感谢您的智慧!
编辑按请求添加“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...
<%= 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？!
最佳答案
在构造 {:action => 'home', :controller => 'pages'} 的 URL 时，Rails 使用相对于渲染当前 View 的 Controller 的路径。
对于登录页面，这将是“devise/sessions”，因此它会在 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 Controller 位于根目录中，而不是在设计命名空间内。
替换:
{:action => 'home', :controller => 'pages'}
这样:
{:action => 'home', :controller => '/pages'}
