Из *операции пути* можно вернуть *элементы перечисления*, даже вложенные в тело JSON (например в `dict`).

Они будут преобразованы в соответствующие значения (в данном случае - строки) перед их возвратом клиенту:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```
Вы отправите клиенту такой JSON-ответ:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

```JSON hl_lines="11"

Então, se você acessar as URLs em `/openapi.json`, `/docs` ou `/redoc`, você receberá apenas um erro `404 Não Encontrado` como:

```JSON
{
    "detail": "Not Found"
}

/// warning | "Achtung"

Sie können mehrere `File`- und `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der Request den Body mittels `multipart/form-data` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.
