次のようにユーザープロファイルを作成します。
class UserProfile(models.Model):
# This field is required:
user = models.OneToOneField(User, related_name="User can view study permission")
# Other fields:

ユーザー向けの拡張情報です。今、私は自分で管理ページを作成して、管理者が上記のユーザー プロファイルを含むユーザー アカウント情報を更新できるようにしています。このフォームとコードは次のとおりです。

管理者が他のユーザーのアカウント情報を編集しようとしても問題なく動作します。ただし、管理者が自分のアカウントを更新しようとしたとき。このフィールドが変更されたかどうかに関係なく、疾患フィールドは常に空白になります。
理由はありますか?コードを変更するにはどうすればよいですか? どうもありがとうございました。
