Например, модель выше описывает такой JSON "`object`" (или Python `dict`):

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

Наприклад, ця модель вище оголошує JSON "`об'єкт`" (або Python `dict`), як:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

            arbitrary_types_allowed=True,
        )
        value: str | Missing = Missing()
        embedded_model: EmbeddedModel = EmbeddedModel()

    @app.post("/")
    def foo(req: Model) -> dict[str, str | None]:
        return {
            "value": req.value or None,
            "embedded_value": req.embedded_model.value or None,
        }

    client = TestClient(app)

The same as when declaring query parameters, when a model attribute has a default value, it is not required. Otherwise, it is required. Use `None` to make it just optional.

For example, this model above declares a JSON "`object`" (or Python `dict`) like:

```JSON
{
    "name": "Foo",
    "description": "An optional description",
    "price": 45.2,
    "tax": 3.5
}
```

#### Über `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` bedeutet:

*Übergib die Schlüssel und Werte des `user_dict` direkt als Schlüssel-Wert-Argumente, äquivalent zu:*

```Python
UserInDB(
    username = user_dict["username"],

{* ../../docs_src/security/tutorial003_an_py310.py hl[82:85] *}

#### About `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` means:

*Pass the keys and values of the `user_dict` directly as key-value arguments, equivalent to:*

```Python
UserInDB(
    username = user_dict["username"],

{* ../../docs_src/security/tutorial003_an_py310.py hl[82:85] *}

#### Sobre `**user_dict` { #about-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"],

Mais par défaut, tout **« just works »**.

### Validation { #validation }

* Validation pour la plupart (ou tous ?) des **types de données** Python, y compris :
    * objets JSON (`dict`).
    * tableaux JSON (`list`) définissant les types d'éléments.
    * champs String (`str`), définition des longueurs minimale et maximale.
    * nombres (`int`, `float`) avec valeurs minimale et maximale, etc.
