ruby-on-rails - 从 rails 3.2.0 升级到 3.2.2 时出现 "new"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。

当使用路由助手生成新路由时，助手会工作并生成一个链接，如下所示:

/things/new

但是，当您访问该链接时，它会引发路由错误...

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

它将它误认为是一个编辑 url 操作而不是一个新的操作。

route 什么都没有，但是......

  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。

额外的细节...

rake 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/}

curl :

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

Answer 1

我猜它不是 /things/new导致问题的路由本身。正在渲染某些内容(例如，您的 _nav 菜单之一)包括对 edit_app_thing_path 的调用。带有 nil 或其他缺少的对象参数。
