ruby-on-rails - Heroku の「問題が発生しました」は本番のみです。ActionView:MissingTemplate エラーですが、テンプレートは存在します

Question

「問題が発生しました」500 エラーが発生するのは、Heroku の本番環境でのみであり、ほぼ完全に非動的なコンテンツがほとんどないページの 1 つに対してのみです。

ログには、次のように表示されています。

ActionView::MissingTemplate (Missing template pages/contact, application/contact with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee, :haml]}. Searched in:
            2013-03-28T03:42:28+00:00 app[web.1]:   * "/app/app/views"
            2013-03-28T03:42:28+00:00 app[web.1]:  

ただし、テンプレートは間違いなくその場所にあります。Heroku run rake routes は正しいルートを示しています。他のフォーラムのアドバイスに従い、uglifier、coffeescript、haml-rails を gemfile のアセット グループから移動しました。Gemfile は次のようになります。

    # Bundle edge Rails instead:

    # Bundle gems for the local environment. Make sure to
    # put test-only gems in this group so their generators
    # and rake tasks are available in development mode:

    # Use unicorn as the app server
    # gem 'unicorn'

    # Deploy with Capistrano

    # To use debugger

ログやその他のスタック オーバーフローの質問には、他に役立つ情報はありません。私が見ていない何かを見ている新鮮な目はありますか？

Answer 1

contact.html.erb が Heroku に到達したことを確認するには、次のコマンドを実行してみてください。

heroku run bash
cat app/views/pages/contact.html.erb

Answer 2

あきらめる前に、回避策として本当に奇妙な雹の予感を決め、問題を解決しました。

問題のファイル「contact.html.erb」、「contact.css.erb」をコピーして、「contact」の代わりに「contacto.html.erb」などの名前の新しいミラー イメージ ファイルに貼り付けました。

ルートを match '/contact' => 'pages#contacto' に変更し、heroku にプッシュしました。エラーがなくなりました。さらに驚くべきことに、元のファイルを削除し、同じファイルの名前を contacto の代わりに「contact」に変更した後も、まだ機能していました。

この作業の背後にあるブードゥー教が本当に理解できません。私はもともとルーティングの回避策を試していました。以前にそれらの「連絡先」ファイルからすべてのコンテンツを削除してherokuにプッシュし、そのすべてのコンテンツを置き換えて、変更せずに再度プッシュしました.
