Javascript 未初始化常数控制器

我正在使用以下ember rails gem创建一个ember rails应用程序

我在教程的最后，但我得到了一个路由错误

在浏览器中：

 uninitialized constant EmberController

在候机楼：

routes.rb

Application::Application.routes.draw do
   namespace :api do
     namespace :v1 do
       resources :posts
     end
   end

   root :to => 'ember#start'
 end

但是，该控制器不存在。事实上，我搜索了整个文件夹，该名称唯一存在的地方就是日志文件。我错过了什么

rake路由的输出

    api_v1_posts GET    /api/v1/posts(.:format)          api/v1/posts#index
                 POST   /api/v1/posts(.:format)          api/v1/posts#create
 new_api_v1_post GET    /api/v1/posts/new(.:format)      api/v1/posts#new

     api_v1_post GET    /api/v1/posts/:id(.:format)      api/v1/posts#show
                 PUT    /api/v1/posts/:id(.:format)      api/v1/posts#update
                 DELETE /api/v1/posts/:id(.:format)      api/v1/posts#destroy
            root        /                                ember#start

这意味着您没有具有启动操作的rails控制器。尝试运行

rails生成控制器余烬启动
。这就是诀窍。非常感谢。
