# Body – Felder

So wie Sie zusätzliche Validation und Metadaten in Parametern der **Pfadoperation-Funktion** mittels `Query`, `Path` und `Body` deklarieren, können Sie auch innerhalb von Pydantic-Modellen zusätzliche Validation und Metadaten deklarieren, mittels Pydantics `Field`.

## `Field` importieren

Importieren Sie es zuerst:
