* `Field(primary_key=True)` tells SQLModel that the `id` is the **primary key** in the SQL database (you can learn more about SQL primary keys in the SQLModel docs).

    By having the type as `int | None`, SQLModel will know that this column should be an `INTEGER` in the SQL database and that it should be `NULLABLE`.

* `Field(primary_key=True)` для SQLModel означает, что поле `id` является первичным ключом в таблице базы данных (вы можете подробнее узнать о первичных ключах баз данных в документации по SQLModel).

    Тип `int | None` сигнализирует для SQLModel, что столбец таблицы базы данных должен иметь тип `INTEGER`, или иметь пустое значение  `NULL`.

## Multiple File Uploads { #multiple-file-uploads }

It's possible to upload several files at the same time.

They would be associated to the same "form field" sent using "form data".

To use that, declare a list of `bytes` or `UploadFile`:
