從rails 3.2.0升級到3.2.2時出現「新」路由問題

Question

從3.2.0升級到3.2.2時，我遇到了路由問題。

當生成一個新的路線與路線幫手助手的作品，併產生一個鏈接，看起來像：

/things/new 

然而，當你訪問它拋出一個路由錯誤的鏈接...

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

它錯誤的編輯網址操作不是一個新的。

沒有什麼的路線，但....

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

有沒有人經歷過這種或知道發生了什麼？

謝謝。

額外的細節...

耙路線：

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/} 

捲曲：

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

從日誌（堆棧跟蹤）：

Answer 1

我猜想這不是導致問題的/things/new路由本身。有些東西正在呈現（例如，您的_nav菜單之一），其中包含對edit_app_thing_path的調用，其中包含零或缺少對象參數。

Answer 2

檢查development.log文件來查看當你訪問「/東西/新」時全堆棧跟蹤。如果您無法看到日誌中出現什麼錯誤，請將其發佈到此處。

乍一看，edit_thing_path(@thing)調用中似乎存在問題：您正在傳遞新記錄 - 我在該錯誤消息中看到了#<Thing id: nil...。

Answer 3

在這裏工作很好。

我不知道該怎麼告訴你Smickie，我重新創建了你的情況，它對我來說工作得很好。這裏還有一些細節：

Rails的版本

$ bundle exec rails -v 
Rails 3.2.2 

的routes.rb

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

耙路線

$ bundle exec rake routes 
    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/} 

獲取things/new

$ curl -IL http://app.test.dev:3001/things/new 
HTTP/1.1 200 OK 
... 

如果您發佈從您的計算機相同的細節，我們會看到什麼可疑。

使用本：

scope "/app" do 
    resources :things 
end
