Mais si vous voulez qu'il attende un JSON avec une clé `item` contenant le contenu du modèle, comme lorsqu'on déclare des paramètres supplémentaires du corps de la requête, vous pouvez utiliser le paramètre spécial `embed` de `Body` :

```Python
item: Item = Body(embed=True)
```

comme dans :

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}

        storedPermits = 0.0;
      } else {
        storedPermits =
            (oldMaxPermits == 0.0)
                ? maxPermits // initial state is cold

    }
