#### Sobre `**user_dict`

`UserInDB(**user_dict)` significa:

*Pasa las claves y valores de `user_dict` directamente como argumentos clave-valor, equivalente a:*

```Python
UserInDB(
    username = user_dict["username"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
    disabled = user_dict["disabled"],

## Valeurs scalaires dans le body

De la même façon qu'il existe `Query` et `Path` pour définir des données supplémentaires pour les paramètres query et path, **FastAPI** fournit un équivalent `Body`.

Par exemple, en étendant le modèle précédent, vous pouvez vouloir ajouter un paramètre `importance` dans le même body, en plus des paramètres `item` et `user`.
