`Depends(scope="request")` (varsayılan) kullanıldığında ise `yield` sonrasındaki çıkış kodu, response gönderildikten sonra çalıştırılır.

Daha fazlasını [`yield` ile Dependency'ler - Erken çıkış ve `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope) dokümantasyonunda okuyabilirsiniz.

使用 `Depends(scope="function")` 时，`yield` 之后的退出代码会在*路径操作函数*结束后、响应发送给客户端之前立即执行。

而当使用默认的 `Depends(scope="request")` 时，`yield` 之后的退出代码会在响应发送之后执行。

你可以在文档 [带 `yield` 的依赖项 - 提前退出与 `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope) 中了解更多。

Birkaç fark var:

* `table=True`, SQLModel’e bunun bir *table model* olduğunu söyler; SQL veritabanında bir **table**’ı temsil etmelidir, sadece bir *data model* değildir (diğer normal Pydantic sınıflarında olduğu gibi).

* `Field(primary_key=True)`, SQLModel’e `id`’nin SQL veritabanındaki **primary key** olduğunu söyler (SQL primary key’leri hakkında daha fazlasını SQLModel dokümantasyonunda öğrenebilirsiniz).
