* `Field(primary_key=True)` le dice a SQLModel que `id` es la **clave primaria** en la base de datos SQL (puedes aprender más sobre claves primarias de SQL en la documentación de SQLModel).

    Al tener el tipo como `int | None`, SQLModel sabrá que esta columna debe ser un `INTEGER` en la base de datos SQL y que debe ser `NULLABLE`.

## Завантаження Кількох Файлів

Можна завантажувати кілька файлів одночасно.

Вони будуть пов’язані з одним і тим самим "form field", який передається у вигляді "form data".

Щоб це реалізувати, потрібно оголосити список `bytes` або `UploadFile`:

{* ../../docs_src/request_files/tutorial002_an_py39.py hl[10,15] *}

    }

    @Override

        int decodedBytes = decoded.decode(buffer, 0, 8);
        assertEquals(8, decodedBytes);
