`dict`、`list`、`str`、`int`などを返すことができます。

Pydanticモデルを返すこともできます（後で詳しく説明します）。

JSONに自動的に変換されるオブジェクトやモデルは他にもたくさんあります（ORMなど）。 お気に入りのものを使ってみてください。すでにサポートされている可能性が高いです。

이는 모든 것이 자동으로 검증되기 때문에, 많은 경우에서 요청을 통해 얻은 동일한 객체를, **직접 데이터베이스로** 넘겨줄 수 있습니다.

반대로도 마찬가지이며, 많은 경우에서 여러분은 **직접 클라이언트로** 그저 객체를 넘겨줄 수 있습니다.
