Question

我的管理区域有一个名为'layout_admin'的布局。在'layout_admin'中，我有：

<li><%= link_to 'Contenu', :action=>'index', :controller=>'contents' %></li>
<li><%= link_to 'Petitions', :controller => 'petitions', :action => 'index' %></li>

Contenu的第一个链接工作正常，但第二个链接（用于请愿）让我犯了一个奇怪的错误：

路由错误没有路线匹配{：controller =＆gt;“admin / edito ”}

在地址栏中我有：localhost：3000 / admin / petitions

在routes.rb中我有：

namespace :admin do resources :petitions 
end

我还必须确切地说“edito”是管理区域外的另一个控制器，它有一个动作“索引”。在routes.rb中，我有关于edito_controller的get "edito/index"。

有人知道问题的根源吗？ Thansk。

查看rake routes左栏中的路线名称？使用该信息构建对不同路径助手的调用：

<li><%= link_to 'Contenu', admin_contents_path %></li>
<li><%= link_to 'Petitions', admin_petitions_path %></li>

一般情况下，您应该如何在Rails 3+应用中构建网址。

阅读Rails Routing from the Outside In了解详情（尤其是2.3: Paths and URLs）。

<强>更新

您应该在访问_path时提取的视图中使用这些/admin/petitions风格的帮助器。

我打赌你在页面上有一个类似于此的链接：

<%= link_to "Link Text", :controller => "edito", :action => "index" %>

它正试图在edito命名空间中找到admin，因为当您访问/admin/petitions时，这就是您在应用中的位置。

要修复，您需要将其更新为如下所示：

<%= link_to "Link Text", edito_index_path %>

对您应用中的所有链接，表单和url_for引用进行清洗，冲洗和重复。

link_to重定向到错误的控制器
