In einigen Fällen müssen Sie möglicherweise immer noch Pydantics Version von `dataclasses` verwenden. Zum Beispiel, wenn Sie Fehler in der automatisch generierten API-Dokumentation haben.

In diesem Fall können Sie einfach die Standard-`dataclasses` durch `pydantic.dataclasses` ersetzen, was einen direkten Ersatz darstellt:
