Не волнуйтесь, с такой структурой кода мы позже обеспечим использование **одной *сессии* SQLModel на запрос**, по сути именно этого и добивается `check_same_thread`.

### Создание таблиц { #create-the-tables }

Далее мы добавим функцию, которая использует `SQLModel.metadata.create_all(engine)`, чтобы **создать таблицы** для всех *моделей-таблиц*.
