バックグラウンド
だから私は、さまざまな方法で互いに関連するモデルがたくさんある Pyramis アプリを持っています。これらのモデルは当初、一般的な役割に応じてさまざまなファイルの束に保管されていました。たとえば、ユーザーとグループの定義を含む auth_models.py というファイルがありました。
すべてのモデルファイルが非常に複雑な方法で相互に関連しているため、インポートなどに対処するために戦ってきたので、あきらめてそれらすべてを同じファイルに配置しました。そして、すべてのインポートステートメントを他の場所で更新して、すべてが機能するようにしました。
ビューにアクセスしようとすると、内部サーバー エラーが発生します。エラーの原因は auth_models.py が存在しないことが原因であることが判明しました。エラーはステートメントから発生しているpicklie.loadsため、ロードされているセッション情報が機能しなくなっていると考えられます。完全なエラー メッセージとセッション設定は、この質問の最後に記載されています。
質問
私の仮定が正しければ、安全な方法で Pyramid に最後のセッションを「忘れさせる」にはどうすればよいでしょうか?
私の仮定が間違っている場合、これを修正する最善の方法は何ですか? 古いディレクトリ構造に戻したくありません。それが原因で問題が発生するからです...
