또는 의존성이 값을 반환하지 않습니다.

그러나 여전히 실행/해결될 필요가 있습니다.

그런 경우에, `Depends`를 사용하여 *경로 작동 함수*의 매개변수로 선언하는 것보다 *경로 작동 데코레이터*에 `dependencies`의 `list`를 추가할 수 있습니다.

## *경로 작동 데코레이터*에 `dependencies` 추가하기

*경로 작동 데코레이터*는 `dependencies`라는 선택적인 인자를 받습니다.

`Depends()`로 된 `list`이어야합니다:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

이러한 의존성들은 기존 의존성들과 같은 방식으로 실행/해결됩니다. 그러나 값은 (무엇이든 반환한다면) *경로 작동 함수*에 제공되지 않습니다.

///

`response_model` receives the same type you would declare for a Pydantic model field, so, it can be a Pydantic model, but it can also be, e.g. a `list` of Pydantic models, like `List[Item]`.

FastAPI will use this `response_model` to do all the data documentation, validation, etc. and also to **convert and filter the output data** to its type declaration.

# JSON-kompatibler Encoder

Es gibt Fälle, da möchten Sie einen Datentyp (etwa ein Pydantic-Modell) in etwas konvertieren, das kompatibel mit JSON ist (etwa ein `dict`, eine `list`e, usw.).

Zum Beispiel, wenn Sie es in einer Datenbank speichern möchten.

Dafür bietet **FastAPI** eine Funktion `jsonable_encoder()`.

## `jsonable_encoder` verwenden

Stellen wir uns vor, Sie haben eine Datenbank `fake_db`, die nur JSON-kompatible Daten entgegennimmt.
