このレールのioerrorクローズドストリームの原因は何ですか？

Question

開発モード（sqliteデータベースを使用）で動作するレールアプリケーションがあります。このアプリケーションの目的は、ユーザーがJavaクライアントを通じてファイルをアップロードできるようにすることです。

ユーザーがフォルダをアップロードする場合、そのフォルダ内のすべてのファイルが再帰的にアップロードされます。ユーザーがファイルをアップロードしたい場合、ファイルは正常にアップロードされます。ここで

は、私が受けてるのエラーです：ここで

IOError 

    in UploadedFilesController#new

私はこれがなぜ起こるのかわかりません。クライアントは、このエラーが表示される前に約15-30個のファイル（フォルダから、Javaクライアントを介して）をアップロードします。私はRails 2.0.2を実行しています。私が開発モードでsqliteをデータベースとして使用して実行しているという事実は、これを引き起こしますか？どんな助けでも大歓迎です！

ありがとうございました！

Answer 1

私はそれを考え出したと思います。少なくとも、私はそう思います（クライアントは現在、エラーのないままアップロードを続けています）。 アップロードしたファイルからデータを読み取った後には、CLOSEもあるはずです。誰が考えただろうか？ ：P

Answer 2

ファイルオブジェクトを閉じるだけではうまくいきませんでしたが（私たちはPaperclipを使用し、ファイルは閉じます）、Railsアプリケーションでも同じ問題が発生しました。私はそれを修正したTempfileクラスのMonkeypatchを開発し、Rails初期化子として使用します。

あなたは、私が同意するだろうhttp://github.com/jwinky/ruby_tempfile_ioerror
