`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**.

Diese Schemadefinition enthält Ihre API-Pfade, die möglichen Parameter, welche diese entgegennehmen, usw.

#### Daten-„Schema“

Der Begriff „Schema“ kann sich auch auf die Form von Daten beziehen, wie z. B. einen JSON-Inhalt.

In diesem Fall sind die JSON-Attribute und deren Datentypen, usw. gemeint.

#### OpenAPI und JSON Schema

    every Contributor for any liability incurred by the Initial
    Developer or such Contributor as a result of any such terms You offer.

    3.6. Larger Works.

    You may create a Larger Work by combining Covered Software with
    other code not governed by the terms of this License and distribute
    the Larger Work as a single product. In such a case, You must make
    sure the requirements of this License are fulfilled for the Covered

Da `Annotated` mehrere Metadaten haben kann, können Sie dieselbe Funktion auch mit anderen Tools verwenden, wie etwa <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">Typer</a>. 🚀

## Mehr Validierungen hinzufügen

Sie können auch einen Parameter `min_length` hinzufügen:
