Rails帮助构建管理区域 – 路由问题

我正在建立一个管理区域。

在app / controllers中

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

在app / controllers / admin中

 kategoris_controller.rb 

我的路线档案：

 resources :kategoris namespace :admin do resources :kategoris end 

我的kategori索引文件在app / views / admin / kategories / index中

 
Listing kategoris
 
 
 
Navn
 
 
 
 
  
 
 
 
 
 'Are you sure?', :method => :delete %>
 
  
 
  

我的kategori控制器在Admin / kategoris_controller.rb中

 class Admin::KategorisController  @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Admin控制器在views / admin / admin_controller.rb中

 class Admin::AdminController < ApplicationController def index end end 

当我访问http：// localhost：3000 / admin / kategoris时出现以下错误：

 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=>#} Extracted source (around line #14): 11:  12:  13:  14:  15:  16: <%= l 

但我能够在http：// localhost：3000 / admin / kategoris / new上创建一个新的然后我重定向到http：// localhost：3000 / kategoris / name-of-new-kategori而不是http：/ /本地主机：3000 /管理/ kategoris /名称-的-新驾驶员学校

您需要重构您的url助手以包含admin命名空间。 在错误的情况下，它是

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

控制器中的重定向也是如此

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

要从控制台中查看所有生成的路由助手

 rake routes
