Ahora intenta enviar un ítem inválido como:

```JSON

  "title": "towel",
  "size": "XL"
}
```

Recibirás un response que te dirá que los datos son inválidos conteniendo el body recibido:

```JSON hl_lines="12-15"

     * Models 4.0.0+ are eligible (4.0.0 has limited inference, 4.1.0+ has full inference).

Beachten Sie, das bedeutet: „`one_person` ist eine **Instanz** der Klasse `Person`“.

Es bedeutet nicht: „`one_person` ist die **Klasse** genannt `Person`“.

## Pydantic-Modelle { #pydantic-models }

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> ist eine Python-Bibliothek für die Validierung von Daten.

Sie deklarieren die „Form“ der Daten als Klassen mit Attributen.

Para distinguir entre los modelos con todos los valores opcionales para **actualizaciones** y modelos con valores requeridos para **creación**, puedes utilizar las ideas descritas en [Modelos Extra](extra-models.md){.internal-link target=_blank}.

 *  Fix: Recover gracefully when a cache entry's certificate is corrupted.

 *  Fix: Fail permanently when there's a failure loading the bundled public suffix database.
    This is the dataset that powers `HttpUrl.topPrivateDomain()`.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the
    receiving stream to process it.

Não estamos restritos a ter apenas uma dependência que possa retornar esse tipo de dado.

## Outros modelos { #other-models }

Agora você pode obter o usuário atual diretamente nas *funções de operação de rota* e lidar com os mecanismos de segurança no nível da **Injeção de Dependências**, usando `Depends`.
