しかし、*path operationデコレータ* に、使いたい `Response` を宣言することもできます。

*path operation関数* から返されるコンテンツは、その `Response` に含まれます。

そしてもし、`Response` が、`JSONResponse` や `UJSONResponse` の場合のようにJSONメディアタイプ (`application/json`) ならば、データは *path operationデコレータ* に宣言したPydantic `response_model` により自動的に変換 (もしくはフィルタ) されます。

/// note | "備考"

メディアタイプを指定せずにレスポンスクラスを利用すると、FastAPIは何もコンテンツがないことを期待します。そのため、生成されるOpenAPIドキュメントにレスポンスフォーマットが記載されません。

{!../../docs_src/body_nested_models/tutorial005.py!}
```

이 문자열이 유효한 URL인지 검사하고 JSON 스키마/OpenAPI로 문서화 됩니다.

## 서브모델 리스트를 갖는 어트리뷰트

`list`, `set` 등의 서브타입으로 Pydantic 모델을 사용할 수도 있습니다:

```Python hl_lines="20"
{!../../docs_src/body_nested_models/tutorial006.py!}
```

아래와 같은 JSON 본문으로 예상(변환, 검증, 문서화 등을)합니다:

```JSON hl_lines="11"
{
    "name": "Foo",
    "description": "The pretender",
