Das liegt daran, dass FastAPI standardmäßig jedes enthaltene Element überprüft und sicherstellt, dass es als JSON serialisierbar ist, und zwar unter Verwendung desselben [JSON-kompatiblen Encoders](../tutorial/encoder.md){.internal-link target=_blank}, der im Tutorial erläutert wurde. Dadurch können Sie **beliebige Objekte** zurückgeben, zum Beispiel Datenbankmodelle.
