그리고 `Response`를 반환하면 **FastAPI**가 이를 그대로 전달합니다.

Pydantic 모델로 데이터 변환을 수행하지 않으며, 내용을 다른 형식으로 변환하지 않습니다.

이로 인해 많은 유연성을 얻을 수 있습니다. 어떤 데이터 유형이든 반환할 수 있고, 데이터 선언이나 유효성 검사를 재정의할 수 있습니다.

## `Response`에서 `jsonable_encoder` 사용하기

**FastAPI**는 반환하는 `Response`에 아무런 변환을 하지 않으므로, 그 내용이 준비되어 있어야 합니다.

예를 들어, Pydantic 모델을 `dict`로 변환해 `JSONResponse`에 넣지 않으면 JSON 호환 유형으로 변환된 데이터 유형(예: `datetime`, `UUID` 등)이 사용되지 않습니다.

Da mesma forma, existem muitas ferramentas compatíveis. Incluindo ferramentas de geração de código para muitas linguagens.

## Pydantic

Toda a validação de dados é feita por baixo dos panos pelo <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>, então você tem todos os benefícios disso. E assim você sabe que está em boas mãos.

Each of those response `dict`s can have a key `model`, containing a Pydantic model, just like `response_model`.

**FastAPI** will take that model, generate its JSON Schema and include it in the correct place in OpenAPI.

For example, to declare another response with a status code `404` and a Pydantic model `Message`, you can write:

{* ../../docs_src/additional_responses/tutorial001.py hl[18,22] *}

Das hat tatsächlich dazu geführt, dass Teile von Pydantic aktualisiert wurden, um denselben Validierungsdeklarationsstil zu unterstützen (diese gesamte Funktionalität ist jetzt bereits in Pydantic verfügbar).

### Pydantic v1 `regex` en lugar de `pattern`

Antes de la versión 2 de Pydantic y antes de FastAPI 0.100.0, el parámetro se llamaba `regex` en lugar de `pattern`, pero ahora está en desuso.

Todavía podrías ver algo de código que lo usa:

//// tab | Pydantic v1

{* ../../docs_src/query_params_str_validations/tutorial004_regex_an_py310.py hl[11] *}

The `Hero` class is very similar to a Pydantic model (in fact, underneath, it actually *is a Pydantic model*).

There are a few differences:

* `table=True` tells SQLModel that this is a *table model*, it should represent a **table** in the SQL database, it's not just a *data model* (as would be any other regular Pydantic class).
