如何在rails 3.1中为作用域/嵌套资源创建named_route_path？

这是我的路线：

scope ":username" do resources :feedbacks end 

当我做rake routes ，我明白了：

  feedbacks GET /:username/feedbacks(.:format) {:action=>"index", :controller=>"feedbacks"} POST /:username/feedbacks(.:format) {:action=>"create", :controller=>"feedbacks"} new_feedback GET /:username/feedbacks/new(.:format) {:action=>"new", :controller=>"feedbacks"} edit_feedback GET /:username/feedbacks/:id/edit(.:format) {:action=>"edit", :controller=>"feedbacks"} feedback GET /:username/feedbacks/:id(.:format) {:action=>"show", :controller=>"feedbacks"} PUT /:username/feedbacks/:id(.:format) {:action=>"update", :controller=>"feedbacks"} DELETE /:username/feedbacks/:id(.:format) {:action=>"destroy", :controller=>"feedbacks"} 

但是当我做feedbacks_url或feedbacks_path时，我得到一个像这样的路由错误：

 No route matches {:controller=>"feedbacks", :format=>nil} 

从日志文件：

 Rendered users/show.html.erb within layouts/application (18.3ms) Completed 500 Internal Server Error in 142ms ActionView::Template::Error (No route matches {:controller=>"feedbacks", :format=>nil}): 1:  2:  3: 
 4: 
 prohibited this feedback from being saved:
 app/views/feedbacks/_form.html.erb:1:in `_app_views_feedbacks__form_html_erb__2195884682603870163_2484875900' app/views/users/show.html.erb:11:in `_app_views_users_show_html_erb__3889159515317937411_2159438040' app/controllers/vanities_controller.rb:14:in `show' 

这是部分feedbacks/_form.html.erb的forms：

   
 
 prohibited this feedback from being saved:
 
  
  
 
   
  current_user.id %>
 
 
  @user.id %>
 
 
  
 
  
   

思考？

好，

 scope ":username" do 

意味着您的路线需要以下信息:username才能正常工作。

然后，您应该在所有链接中添加此信息：

 user_path(user, :username => "joe") edit_user_path(user, :username => "joe") ... 

或者您可以告诉您的应用程序username不是强制性的，如果用户尚未创建，这似乎是逻辑。 所以改变您的路线：

 scope "(:username)" do resources :feedbacks end
