以下のように`Field`をモデルの属性として使用することができます:

{* ../../docs_src/body_fields/tutorial001.py hl[11,12,13,14] *}

`Field`は`Query`や`Path`、`Body`と同じように動作し、全く同様のパラメータなどを持ちます。

/// note | 技術詳細

実際には次に見る`Query`や`Path`などは、共通の`Param`クラスのサブクラスのオブジェクトを作成しますが、それ自体はPydanticの`FieldInfo`クラスのサブクラスです。

また、Pydanticの`Field`は`FieldInfo`のインスタンスも返します。

`Body`は`FieldInfo`のサブクラスのオブジェクトを直接返すこともできます。そして、他にも`Body`クラスのサブクラスであるものがあります。

`Field`는 `Query`, `Path`와 `Body`와 같은 방식으로 동작하며, 모두 같은 매개변수들 등을 가집니다.

/// note | 기술적 세부사항

실제로 `Query`, `Path`등, 여러분이 앞으로 볼 다른 것들은 공통 클래스인 `Param` 클래스의 서브클래스 객체를 만드는데, 그 자체로 Pydantic의 `FieldInfo` 클래스의 서브클래스입니다.

그리고 Pydantic의 `Field` 또한 `FieldInfo`의 인스턴스를 반환합니다.

`Body` 또한 `FieldInfo`의 서브클래스 객체를 직접적으로 반환합니다. 그리고 `Body` 클래스의 서브클래스인 것들도 여러분이 나중에 보게될 것입니다.
