python - Django: django-pyodbc-azure を使用すると、'unicode' オブジェクトに属性 'tzinfo' エラーがありません

Question

内部 MSSQL データベース用の単純な Web フロントエンドの作成を依頼されました。私は django-pyodbc-azure を使用しています。

最終的にすべてを構成して実行しましたが、管理ページにログインしようとすると、「unicode」オブジェクトに「tzinfo」属性がありませんというエラーが表示されます。ここで提案を試みましたが、役に立たなかったようです。どんな提案でも大歓迎です！

Answer 1

解決策は宮本によって投稿されました。Django のデータベース接続オプションに'use_legacy_datetime': Trueという行を追加する必要があり、データベース内のすべての Datetime2 列を手動で Datetime に変更する必要がありました。

ソリューションの詳細については、こちらを参照してください。
