/// tip | Dica

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
}
```

Por exemplo, o modelo acima declara um JSON "`object`" (ou `dict` no Python) como esse:

```JSON
{
    "name": "Foo",
    "description": "Uma descrição opcional",
    "price": 45.2,
    "tax": 3.5
}
```

```Python hl_lines="20"
{!../../docs_src/path_params/tutorial005.py!}
```

	Você também poderia acessar o valor `"lenet"` com `ModelName.lenet.value`

#### Retorne *membros de enumeration*

Você pode retornar *membros de enum* da sua *rota de operação*, em um corpo JSON aninhado (por exemplo um `dict`).

licenses(["notice"])

    "LICENSE",
    # The leakr files are used by //third_party/cloud_tpu and
    # //third_party/tensorboard/google:copybara_config_test.
    "leakr_badwords.dic",

    TENSORFLOW_API_INIT_FILES +
    get_compat_files(TENSORFLOW_API_INIT_FILES, 2) +

Neste caso, o cabeçalho HTTP `Content-Type` irá ser definido como `application/json`.

E será documentado como tal no OpenAPI.

A `ORJSONResponse` está disponível apenas no FastAPI, e não no Starlette.

## Resposta HTML

Para retornar uma resposta com HTML diretamente do **FastAPI**, utilize `HTMLResponse`.
