Then we return the same *table model* `Hero` as is from the function. But as we declare the `response_model` with the `HeroPublic` *data model*, **FastAPI** will use `HeroPublic` to validate and serialize the data.

### `Union` no Python 3.10 { #union-in-python-3-10 }

Neste exemplo, passamos `Union[PlaneItem, CarItem]` como o valor do argumento `response_model`.

Dado que estamos passando-o como um **valor para um argumento** em vez de colocá-lo em uma **anotação de tipo**, precisamos usar `Union` mesmo no Python 3.10.

But if you return a `Response` directly (or any subclass, like `JSONResponse`), the data won't be automatically converted (even if you declare a `response_model`), and the documentation won't be automatically generated (for example, including the specific "media type", in the HTTP header `Content-Type` as part of the generated OpenAPI).

Wenn Sie jedoch direkt eine `Response` (oder eine Unterklasse wie `JSONResponse`) zurückgeben, werden die Daten nicht automatisch konvertiert (selbst wenn Sie ein `response_model` deklariert haben), und die Dokumentation wird nicht automatisch generiert (zum Beispiel wird der spezifische „Medientyp“, der im HTTP-Header `Content-Type` angegeben ist, nicht Teil der generierten OpenAPI).

    access_token = create_access_token(
        data={"sub": user.username}, expires_delta=access_token_expires
    )
    return Token(access_token=access_token, token_type="bearer")


@app.get("/users/me/", response_model=User)
async def read_users_me(
    current_user: Annotated[User, Depends(get_current_active_user)],
):
    return current_user


@app.get("/users/me/items/")
async def read_own_items(

이를 재정의 하려면 [응답을 직접 반환하기](response-directly.md){.internal-link target=_blank}에서 본 것처럼 `Response`를 직접 반환하면 됩니다.

그러나 `Response` (또는 `JSONResponse`와 같은 하위 클래스)를 직접 반환하면, 데이터가 자동으로 변환되지 않으며 (심지어 `response_model`을 선언했더라도), 문서화가 자동으로 생성되지 않습니다(예를 들어, 생성된 OpenAPI의 일부로 HTTP 헤더 `Content-Type`에 특정 "미디어 타입"을 포함하는 경우).

하지만 *경로 작업 데코레이터*에서 `response_class` 매개변수를 사용하여 원하는 `Response`(예: 모든 `Response` 하위 클래스)를 선언할 수도 있습니다.
