Você teria **um único objeto `engine`** para todo o seu código se conectar ao mesmo banco de dados.

Usar `check_same_thread=False` permite que o FastAPI use o mesmo banco de dados SQLite em diferentes threads. Isso é necessário, pois **uma única requisição** pode usar **mais de uma thread** (por exemplo, em dependências).

Параметр `check_same_thread=False` позволяет FastAPI использовать одну и ту же базу данных SQLite в разных потоках. Это необходимо, так как **один запрос** может использовать **больше одного потока** (например, в зависимостях).

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 }

Tendrías **un solo objeto `engine`** para todo tu código para conectar a la misma base de datos.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

Usar `check_same_thread=False` permite a FastAPI usar la misma base de datos SQLite en diferentes hilos. Esto es necesario ya que **una sola request** podría usar **más de un hilo** (por ejemplo, en dependencias).

        clear_sqlmodel()
        importlib.reload(mod)
    mod.sqlite_url = "sqlite://"
    mod.engine = create_engine(
        mod.sqlite_url, connect_args={"check_same_thread": False}, poolclass=StaticPool
    )

    with TestClient(mod.app) as c:
        yield c
    # Clean up connection explicitly to avoid resource warning
    mod.engine.dispose()

Using `check_same_thread=False` allows FastAPI to use the same SQLite database in different threads. This is necessary as **one single request** could use **more than one thread** (for example in dependencies).

Don't worry, with the way the code is structured, we'll make sure we use **a single SQLModel *session* per request** later, this is actually what the `check_same_thread` is trying to achieve.

Sie hätten **ein einziges `engine`-Objekt** für Ihren gesamten Code, um sich mit derselben Datenbank zu verbinden.
