Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.

Wenn Sie eine Exception auslösen, wird, wie es bei normalem Python der Fall wäre, der Rest der Ausführung abgebrochen. Auf diese Weise können Sie diese Exceptions von überall im Code werfen, um einen Request abzubrechen und den Fehler dem Client anzuzeigen.

Sie können Folgendes verwenden:

* `HTTPException`

* **Alembic**-Migrationen.
* **CORS** (Cross Origin Resource Sharing).
* **Celery**-Worker, welche Modelle und Code aus dem Rest des Backends selektiv importieren und verwenden können.

Django REST Frameworkは、Djangoを下敷きにしてWeb APIを構築する柔軟なツールキットとして、APIの機能を向上させるために作られました。

Mozilla、Red Hat、Eventbrite など多くの企業で利用されています。

これは**自動的なAPIドキュメント生成**の最初の例であり、これは**FastAPI**に向けた「調査」を触発した最初のアイデアの一つでした。

            By default, after a dependency is called the first time in a request, if
            the dependency is declared again for the rest of the request (for example
            if the dependency is needed by several dependencies), the value will be
            re-used for the rest of the request.

            Set `use_cache` to `False` to disable this behavior and ensure the

    The `APIRouter`s are not "mounted", they are not isolated from the rest of the application.

    This is because we want to include their *path operations* in the OpenAPI schema and the user interfaces.

    As we cannot just isolate them and "mount" them independently of the rest, the *path operations* are "cloned" (re-created), not included directly.
