/// note | 備考

`response_model`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数* のパラメータではありません。

///

Pydanticモデルの属性に対して宣言するのと同じ型を受け取るので、Pydanticモデルになることもできますが、例えば、`List[Item]`のようなPydanticモデルの`list`になることもできます。

FastAPIは`response_model`を使って以下のことをします:

* 出力データを型宣言に変換します。
* データを検証します。
* OpenAPIの *path operation* で、レスポンス用のJSON Schemaを追加します。
* 自動ドキュメントシステムで使用されます。

しかし、最も重要なのは:
