/// tip | Tipp

Andere Möglichkeiten, einen Kontextmanager zu erstellen, sind:

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) oder
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

Vous devez vous assurer d'utiliser `yield` une seule fois par dépendance.

///

/// note | Détails techniques

Toute fonction valide à utiliser avec :

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) ou
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

sera valide comme dépendance **FastAPI**.

Asegúrate de usar `yield` una sola vez por dependencia.

///

/// note | Detalles técnicos

Cualquier función que sea válida para usar con:

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) o
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

sería válida para usar como una dependencia en **FastAPI**.

要做到這點，使用 `yield` 取代 `return`，並把額外步驟（程式碼）寫在其後。

/// tip

請確保每個相依內只使用一次 `yield`。

///

/// note | 技術細節

任何可用於下列裝飾器的函式：

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) 或
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

都可以作為 **FastAPI** 的相依。

事實上，FastAPI 內部就是使用這兩個裝飾器。

Her dependency için yalnızca bir kez `yield` kullandığınızdan emin olun.

///

/// note | Teknik Detaylar

Şunlarla kullanılabilen herhangi bir fonksiyon:

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) veya
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

bir **FastAPI** dependency'si olarak kullanılabilir.

Переконайтесь, що ви використовуєте `yield` лише один раз на залежність.

///

/// note | Технічні деталі

Будь-яка функція, яку можна використовувати з:

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) або
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

буде придатною як залежність у **FastAPI**.

/// tip

Make sure to use `yield` one single time per dependency.

///

/// note | Technical Details

Any function that is valid to use with:

* [`@contextlib.contextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager) or
* [`@contextlib.asynccontextmanager`](https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager)

would be valid to use as a **FastAPI** dependency.
