/// tip

The important and "magic" thing here is that `get_current_user` will have a different list of `scopes` to check for each *path operation*.

All depending on the `scopes` declared in each *path operation* and each dependency in the dependency tree for that specific *path operation*.

Sie können auch `from starlette.responses import Response` oder `from starlette.responses import JSONResponse` verwenden.

Aber FastAPI unterstützt auf die gleiche Weise auch die Verwendung von <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>:

Wie auch bei der Deklaration von Query-Parametern gilt: Wenn ein Modellattribut einen Defaultwert hat, ist das Attribut nicht erforderlich. Andernfalls ist es erforderlich. Verwenden Sie `None`, um es einfach optional zu machen.

///

`response_model` nimmt denselben Typ entgegen, den Sie auch für ein Pydantic-Modellfeld deklarieren würden, also etwa ein Pydantic-Modell, aber es kann auch z. B. eine `list`e von Pydantic-Modellen sein, wie etwa `List[Item]`.

FastAPI wird dieses `response_model` nehmen, um die Daten zu dokumentieren, validieren, usw. und auch, um **die Ausgabedaten** entsprechend der Typdeklaration **zu konvertieren und filtern**.
