`item`이 이전과 같은 방식으로 선언되었더라도, 이제는 본문에서 `item` 키 안에 있을 것으로 예상된다는 점을 유의하세요.

そして、セキュリティ要件のためにどんなモデルやデータでも利用することができます。（この場合は、 Pydanticモデルの `User`）

しかし、特定のデータモデルやクラス、型に制限されることはありません。

モデルを、 `id` と `email` は持つが、 `username` は全く持たないようにしたいですか？ わかりました。同じ手段でこうしたこともできます。

ある `str` だけを持ちたい？ あるいはある `dict` だけですか？ それとも、データベースクラスのモデルインスタンスを直接持ちたいですか？ すべて同じやり方で機能します。
