## Retorno Adicional com `model` { #additional-response-with-model }

Você pode fornecer o parâmetro `responses` aos seus *decoradores de caminho*.

Este parâmetro recebe um `dict`, as chaves são os códigos de status para cada retorno, como por exemplo `200`, e os valores são um outro `dict` com a informação de cada um deles.

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

Como ele não inclui o atributo já armazenado `"tax": 20.2`, o modelo de entrada assumiria o valor padrão de `"tax": 10.5`.

E os dados seriam salvos com esse "novo" `tax` de `10.5`.

## Atualizações parciais com `PATCH` { #partial-updates-with-patch }

# Middleware

There are several middlewares available provided by Starlette directly.
