私は以下を取得しています：
Started DELETE "/comments/13115742" for 127.0.0.1 at 2012-11-26 14:37:32 -0800
ActionController::RoutingError (No route matches [DELETE] "/comments/13115742"):
しかし、「rake routes」はこのルートを明確に示しています:
$ rake routes
comments POST /comments(.:format) comments#create {:id=>/0-9+/, :format=>/json|html/}
comment GET /comments/:id(.:format) comments#show {:id=>/0-9+/, :format=>/json|html/}
PUT /comments/:id(.:format) comments#update {:id=>/0-9+/, :format=>/json|html/}
DELETE /comments/:id(.:format) comments#destroy {:id=>/0-9+/, :format=>/json|html/}
そして、routes.rb には明確にルートが定義されています。
resources :comments, :constraints => {:id => /0-9+/, :format => /json|html/}, :except => [:new, :index, :edit]
コメント コントローラーがあり、コンソールからのルーティングも機能しないことに注意してください。
