* Vous devriez maintenant avoir une structure de répertoire telle que :

```
.
├── app
│   └── main.py
└── Dockerfile
```

    * Это сравнимо с повторным использованием метода модели `.dict()`, но при этом происходит проверка (и преобразование) значений в типы данных, которые могут быть преобразованы в JSON, например, `datetime` в `str`.
* Сохранить данные в своей БД.
* Вернуть обновленную модель.
