Es ist immer noch möglich, `BackgroundTask` allein in FastAPI zu verwenden, aber Sie müssen das Objekt in Ihrem Code erstellen und eine Starlette-`Response` zurückgeben, die es enthält.

You will have inline errors for the data that you send:

The response object will also have autocompletion:

**FastAPI**は<a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic </strong></a>と完全に互換性があります（そしてベースになっています）。したがって、追加のPydanticコードがあれば、それも機能します。

データベースのために<abbr title = "Object-Relational Mapper">ORM</abbr>sや、<abbr title = "Object-Document Mapper">ODM</abbr>sなどの、Pydanticに基づく外部ライブラリを備えています。

これは、すべてが自動的に検証されるため、多くの場合、リクエストから取得したオブジェクトを**データベースに直接**渡すことができるということを意味しています。
