从rails 3.2.0升级到3.2.2时出现"新"路由问题

Question

将rails从3.2.0升级到3.2.2时,我遇到了一些路由问题.

当生成具有路径帮助程序的新路由时,帮助程序工作并生成如下所示的链接:

/things/new

但是,当您访问该链接时,它会抛出路由错误...

Routing Error
No route matches {:action=>"edit", :controller=>"app/things", :id=>#<Thing id: nil, title: n....

它使编辑网址操作错误,而不是新操作.

路线上什么也没有......

  scope :module => :app, :as => :app, :constraints => { :subdomain => /app/ } do
     resources :things
  end

有没有人经历过这个或知道发生了什么？

谢谢.

额外细节......

耙路线:

    app_things GET    /things(.:format)                                    app/things#index {:subdomain=>/app/}
               POST   /things(.:format)                                    app/things#create {:subdomain=>/app/}
 new_app_thing GET    /things/new(.:format)                                app/things#new {:subdomain=>/app/}
edit_app_thing GET    /things/:id/edit(.:format)                           app/things#edit {:subdomain=>/app/}
     app_thing GET    /things/:id(.:format)                                app/things#show {:subdomain=>/app/}
               PUT    /things/:id(.:format)                                app/things#update {:subdomain=>/app/}
               DELETE /things/:id(.:format)                                app/things#destroy {:subdomain=>/app/}

卷曲:

curl -IL http://app.testapp.com/things/new
HTTP/1.1 404 Not Found 

从日志(堆栈跟踪？):

我猜这不是/things/new导致问题的路线本身.有一些东西被渲染(例如你的一个_nav菜单),包括edit_app_thing_path使用nil或其他缺少的对象参数调用.
