Ruby on rails Rails帮助构建管理区域-路由问题

我正在做一个行政区

应用程序内/控制器

application_controller.rb
public_controller.rb
admin_controller.rb
kategoris_controller.rb

和应用程序内/控制器/管理员

kategoris_controller.rb

我的路线文件：

resources :kategoris
namespace :admin do
  resources :kategoris
end

app/views/admin/kategories/index中的我的kategori索引文件

<h1>Listing kategoris</h1>

<table>
  <tr>
    <th>Navn</th>
    <th></th>
    <th></th>
    <th></th>
  </tr>

<% @kategoris.each do |kategori| %>
  <tr>
    <td><%= kategori.name %></td>
    <td><%= link_to 'Show', kategori %></td>
    <td><%= link_to 'Edit', edit_kategori_path(kategori) %></td>
    <td><%= link_to 'Destroy', kategori, :confirm => 'Are you sure?', :method => :delete %></td>
  </tr>
<% end %>
</table>

<br />

<%= link_to 'New Kategori', new_kategori_path %>

---

您需要重构url帮助程序，以包含管理员名称空间。在错误的情况下，应该是

<td><%= link_to 'Show', admin_kategori_path(kategori) %></td>

要查看所有生成的路由帮助程序，请从控制台执行以下操作：

rake routes

---

在视图中获取此错误：没有路由匹配{:action=>“show”，：controller=>“admin/kategoris”，：id=>由于某些原因，您的控制器无法识别。admin文件夹的名称是否大写？您提到“admin/kategoris_controller.rb”-它应该是admin/kategoris_controller.rbit位于admin/kategoris_controller中。rbit有助于查看完整的stacktrace和rake routes输出，您是否将其发布在Paste或gist上并向我们发送链接？我有osted开发日志还需要查看“rake routes”的输出我已经在您的routes中发布了routestry

名称空间：admin do | admin | admin.resources:kategoris end

我得到一个错误：方法缺少未定义的方法资源
