# JSON 호환 가능 인코더 { #json-compatible-encoder }

데이터 유형(예: Pydantic 모델)을 JSON과 호환되는 형태(예: `dict`, `list` 등)로 변환해야 하는 경우가 있습니다.

예를 들면, 데이터베이스에 저장해야 하는 경우입니다.

이를 위해, **FastAPI**에서는 `jsonable_encoder()` 함수를 제공합니다.

## `jsonable_encoder` 사용 { #using-the-jsonable-encoder }

JSON 호환 가능 데이터만 수신하는 `fake_db` 데이터베이스가 존재한다고 가정하겠습니다.

예를 들면, `datetime` 객체는 JSON과 호환되지 않으므로 이 데이터베이스는 이를 받지 않습니다.
