Stellen Sie sicher, dass Sie eine [Virtuelle Umgebung](../virtual-environments.md) erstellen, sie aktivieren und es dann installieren, zum Beispiel:

```console
$ pip install python-multipart
```

## Pydantic-Modelle für Formulare { #pydantic-models-for-forms }

Assurez-vous de créer un [environnement virtuel](../virtual-environments.md), de l'activer, puis d'installer le paquet, par exemple :

```console
$ pip install python-multipart
```

/// note | Remarque

Ceci est pris en charge depuis la version `0.113.0` de FastAPI. 🤓

## Modèles Pydantic pour les formulaires { #pydantic-models-for-forms }

 *   <li>[2001:db8::1] - {@link #getHost()} omits brackets
 *   <li>[2001:db8::1]:80 - {@link #getHost()} omits brackets
 *   <li>2001:db8::1 - Use {@link #requireBracketsForIPv6()} to prohibit this
 * </ul>
 *
 * <p>Note that this is not an exhaustive list, because these methods are only concerned with
 * brackets, colons, and port numbers. Full validation of the host field (if desired) is the
 * caller's responsibility.
