Rails幫助建立管理區域 - 路由問題

在app /控制器

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

而在應用/控制器/管理

kategoris_controller.rb

我的路由文件：

resources :kategoris 
namespace :admin do 
    resources :kategoris 
end

我在app /視圖/管理駕駛員學校索引文件/ kategories/index

<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 %>

我控制器駕駛員學校在管理中的意見/ kategoris_controller.rb

class Admin::KategorisController < Admin::AdminController 
    # GET /kategoris 
    # GET /kategoris.xml 
    def index 
    @kategoris = Kategori.all 

    respond_to do |format| 
     format.html # index.html.erb 
     format.xml { render :xml => @kategoris } 
    end 
    end 

    # GET /kategoris/1 
    # GET /kategoris/1.xml 
    def show 
    @kategori = Kategori.find(params[:id]) 

    respond_to do |format| 
     format.html # show.html.erb 
     format.xml { render :xml => @kategori } 
    end 
    end 

    # GET /kategoris/new 
    # GET /kategoris/new.xml 
    def new 
    @kategori = Kategori.new 

    respond_to do |format| 
     format.html # new.html.erb 
     format.xml { render :xml => @kategori } 
    end 
    end 

    # GET /kategoris/1/edit 
    def edit 
    @kategori = Kategori.find(params[:id]) 
    end 

    # POST /kategoris 
    # POST /kategoris.xml 
    def create 
    @kategori = Kategori.new(params[:kategori]) 

    respond_to do |format| 
     if @kategori.save 
     format.html { redirect_to(@kategori, :notice => 'Kategori was successfully created.') } 
     format.xml { render :xml => @kategori, :status => :created, :location => @kategori } 
     else 
     format.html { render :action => "new" } 
     format.xml { render :xml => @kategori.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 

    # PUT /kategoris/1 
    # PUT /kategoris/1.xml 
    def update 
    @kategori = Kategori.find(params[:id]) 

    respond_to do |format| 
     if @kategori.update_attributes(params[:kategori]) 
     format.html { redirect_to(@kategori, :notice => 'Kategori was successfully updated.') } 
     format.xml { head :ok } 
     else 
     format.html { render :action => "edit" } 
     format.xml { render :xml => @kategori.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 

    # DELETE /kategoris/1 
    # DELETE /kategoris/1.xml 
    def destroy 
    @kategori = Kategori.find(params[:id]) 
    @kategori.destroy 

    respond_to do |format| 
     format.html { redirect_to(kategoris_url) } 
     format.xml { head :ok } 
    end 
    end 
end

我的管理控制/管理/ admin_controller.rb

class Admin::AdminController < ApplicationController 
def index 
end 
end

當我訪問http://localhost:3000/admin/kategoris我獲得以下錯誤：

ActionController::RoutingError in Admin/kategoris#index 

Showing C:/Rails/konkurranceportalen/app/views/admin/kategoris/index.html.erb where line #14 raised: 

No route matches {:action=>"show", :controller=>"kategoris", :id=>#<Kategori id: 1, name: "Elektronik", created_at: "2011-02-17 04:18:11", updated_at: "2011-02-17 04:18:11", cached_slug: "">} 

Extracted source (around line #14): 

11: <% @kategoris.each do |kategori| %> 
12: <tr> 
13:  <td><%= kategori.name %></td> 
14:  <td><%= link_to 'Show', kategori %></td> 
15:  <td><%= link_to 'Edit', edit_kategori_path(kategori) %></td> 
16:  <td><%= l

但我能夠創建一個新的http://localhost:3000/admin/kategoris/new 然後我重定向到http://localhost:3000/kategoris/name-of-new-kategori 代替http://localhost:3000/admin/kategoris/name-of-new-kategori

會需要看到'rake routes'的輸出以及 – oliverbarnes 2011-03-03 15:33:48

我已經發布了路線 – 2011-03-03 16:36:06

嘗試'namespace：admin do | admin | admin.resources：kategoris end'在你的路由 – oliverbarnes 2011-03-03 17:14:32

你需要重構你的網址助手包括管理員命名空間。在錯誤的情況下，它會是

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

也是一樣的控制器

#in AdminController#create 
redirect_to(admin_kategori_path(@kategori))

要查看所有生成的路徑幫手重定向，從控制檯執行

rake routes

獲取鑑於此錯誤：沒有路由匹配{：動作=>「秀」，：控制器=>「管理/ kategoris 「，：id => – 2011-03-03 14:36:59

Url：http：// localhost：3000/admin/kategoris – 2011-03-03 14:41:27

由於某些原因您的控制器無法識別。 admin文件夾的名字是大寫的？你提到了'Admin/kategoris_controller.rb' - 它應該是admin/kategoris_controller.rb – oliverbarnes 2011-03-03 14:43:10
