## Parâmetros opcionais { #optional-parameters }

Da mesma forma, você pode declarar parâmetros de consulta opcionais, definindo o valor padrão para `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

Nesse caso, o parâmetro da função `q` será opcional, e `None` será o padrão.

## Parámetros opcionales { #optional-parameters }

De la misma manera, puedes declarar parámetros de query opcionales, estableciendo su valor por defecto en `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

En este caso, el parámetro de función `q` será opcional y será `None` por defecto.

rue)` сообщает SQLModel, что `id` — это **первичный ключ** в SQL базе данных (подробнее о первичных ключах SQL можно узнать в документации SQLModel).

    **Примечание:** Мы используем `int | None` для поля первичного ключа, чтобы в Python-коде можно было *создать объект без `id`* (`id=None`), предполагая, что база данных *сгенерирует его при сохранении*. SQLModel понимает, что база данных предоставит `id`, и *определяет столбец как `INTEGER` (не `NULL`)* в схеме базы данных. См. <a href...
