app = FastAPI()


class UserIn(BaseModel):
    username: str
    password: str
    email: EmailStr
    full_name: Union[str, None] = None


class UserOut(BaseModel):
    username: str
    email: EmailStr
    full_name: Union[str, None] = None


@app.post("/user/", response_model=UserOut)
async def create_user(user: UserIn) -> Any:

```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

будет равнозначен такому:

```Python
UserInDB(**user_in.dict())
```

...потому что `user_in.dict()` - это `dict`, и затем мы указываем, чтобы Python его "распаковал", когда передаём его в `UserInDB` и ставим перед ним `**`.

```

Or more exactly, using `user_dict` directly, with whatever contents it might have in the future:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### A Pydantic model from the contents of another

As in the example above we got `user_dict` from `user_in.dict()`, this code:

    ```

## Eine `get_current_user`-Abhängigkeit erstellen

Erstellen wir eine Abhängigkeit `get_current_user`.

Erinnern Sie sich, dass Abhängigkeiten Unterabhängigkeiten haben können?

`get_current_user` wird seinerseits von `oauth2_scheme` abhängen, das wir zuvor erstellt haben.

!!! note "기술 세부사항"
    응답 모델은 함수의 타입 어노테이션 대신 이 매개변수로 선언하는데, 경로 함수가 실제 응답 모델을 반환하지 않고 `dict`, 데이터베이스 객체나 기타 다른 모델을 `response_model`을 사용하여 필드 제한과 직렬화를 수행하고 반환할 수 있기 때문입니다

## 동일한 입력 데이터 반환

여기서 우리는 평문 비밀번호를 포함하는 `UserIn` 모델을 선언합니다:

```Python hl_lines="9  11"
{!../../../docs_src/response_model/tutorial002.py!}
```

그리고 이 모델을 사용하여 입력을 선언하고 같은 모델로 출력을 선언합니다:

```Python hl_lines="17-18"
