例えば、Pydanticモデルを `JSONResponse` に含めるには、すべてのデータ型 (`datetime` や `UUID` など) をJSON互換の型に変換された `dict` に変換しなければなりません。

このようなケースでは、レスポンスにデータを含める前に `jsonable_encoder` を使ってデータを変換できます。

```Python hl_lines="6-7  21-22"
{!../../docs_src/response_directly/tutorial001.py!}
```

/// note | "技術詳細"

また、`from starlette.responses import JSONResponse` も利用できます。

Você pode conectar o depurador no seu editor, por exemplo, com o Visual Studio Code ou PyCharm.

## Chamar `uvicorn`

Em seu aplicativo FastAPI, importe e execute `uvicorn` diretamente:

```Python hl_lines="1  15"
{!../../docs_src/debugging/tutorial001.py!}
```

### Sobre `__name__ == "__main__"`

O objetivo principal de `__name__ == "__main__"` é ter algum código que seja executado quando seu arquivo for chamado com:

<div class="termy">

같은 방식으로 이 데이터베이스는 Pydantic 모델(속성이 있는 객체)을 받지 않고, `dict` 만을 받습니다.

이를 위해 `jsonable_encoder` 를 사용할 수 있습니다.

Pydantic 모델과 같은 객체를 받고 JSON 호환 가능한 버전으로 반환합니다:

```Python hl_lines="5  22"
{!../../docs_src/encoder/tutorial001.py!}
```

이 예시는 Pydantic 모델을 `dict`로, `datetime` 형식을 `str`로 변환합니다.
