Question

我对Ruby / Rails比较陌生，搞砸了case/when条款的结构，或者我不理解路线......

浏览器出错只是：No route matches {:action=>"show", :controller=>"masters"}

但很清楚地看rake routes我看到了：

 master GET   /masters/:id(.:format)    {:action=>"show", :controller=>"masters"}
 breeder GET  /breeders/:id(.:format)   {:action=>"show", :controller=>"breeders"}

并且两个（masters＆amp; breeders）控制器都有show个方法......

哪里是我的傻瓜？

#app/controllers/dogs_controller.rb
class DogsController < ApplicationController

  def create
    @parent = parent_object
    @dog = @parent.dogs.create(params[:dog])
    puts parent_path
    redirect_to parent_path(@parent)
  end

  def destroy
    @parent = parent_object
    @dog = @parent.dogs.find(params[:id])
    @dog.destroy
    redirect_to parent_path(@parent)
  end

  private

  def parent_object
    case 
      when params[:master_id] then Master.find(params[:master_id]) && parent_path = master_path
      when params[:breeder_id] then Breeder.find(params[:breeder_id]) && parent_path = breeder_path
    end
  end
end

修改：添加了MastersController

#app/controllers/masters_controller.rb
class MastersController < ApplicationController
    respond_to :html, :json

    def index
        respond_with(@masters = Master.all)
    end

    def show
        respond_with(@master = Master.find(params[:id]))
    end

    def new
        respond_with(@master = Master.new)
    end

    def edit
        respond_with(@master = Master.find(params[:id]))
    end

    def create
         @master = Master.new(params[:master])
         flash[:notice] = 'Master was successfully created.' if @master.save
         respond_with(@master) 
    end

    def update
        @master = Master.find(params[:id])
        flash[:notice] = 'Master has been updated.' if @master.update_attributes(params[:master])
        respond_with(@master)
    end

    def destroy
        @master = Master.find(params[:id])
        flash[:notice] = 'Successfully deleted master.' if @master.destroy
        respond_with(@master)
    end
end

哈！找到了！我的重定向错误......应该是redirect_to @parent，而不是像我一样构建一些parent_path(@parent) ...

我的Ruby代码错误...或Rails路由？
