from pydantic import BaseModel

# Deklarieren Sie eine Variable als ein str
# und bekommen Sie Editor-Unterstützung innerhalb der Funktion
def main(user_id: str):
    return user_id


# Ein Pydantic-Modell
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Das kann nun wie folgt verwendet werden:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

Обратите внимание, что функция `Field` импортируется непосредственно из `pydantic`, а не из `fastapi`, как все остальные функции (`Query`, `Path`, `Body` и т.д.).

///

## Объявление атрибутов модели { #declare-model-attributes }

Вы можете использовать функцию `Field` с атрибутами модели:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

    DependencyResolutionResult getDependencyResolutionResult();

    // for each exception
    // - knowing what artifacts are missing
    // - project building exception
    // - invalid project model exception: list of markers
    // - xmlpull parser exception
    List<Throwable> getExceptions();

    MavenExecutionResult addException(Throwable e);

    boolean hasExceptions();

And then you can set cookies in that *temporal* response object.

{* ../../docs_src/response_cookies/tutorial002_py39.py hl[1, 8:9] *}

And then you can return any object you need, as you normally would (a `dict`, a database model, etc).

And if you declared a `response_model`, it will still be used to filter and convert the object you returned.
