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

/// note | 기술 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.

# ボディ - フィールド { #body-fields }

`Query`や`Path`、`Body`を使って *path operation関数* のパラメータに追加のバリデーションやメタデータを宣言するのと同じように、Pydanticの`Field`を使ってPydanticモデルの内部でバリデーションやメタデータを宣言することができます。

## `Field`のインポート { #import-field }

まず、以下のようにインポートします:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning | 注意

`Field`は他の全てのもの（`Query`、`Path`、`Body`など）とは違い、`fastapi`からではなく、`pydantic`から直接インポートされていることに注意してください。

- **Path Operation Explorer** - A sidebar tree view of all <dfn title="routes, endpoints">*path operations*</dfn> in your application. Click to jump to any route or router definition.
- **Route Search** - Search by path, method, or name with <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>E</kbd> (on macOS: <kbd>Cmd</kbd> + <kbd>Shift</kbd> + <kbd>E</kbd>).

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this README). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install.html). You should also add the Go binary directory $GOROOT/bin to your shell's path. For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile: export GOROOT=$HOME/go...

    public UpgradeResult doApply(UpgradeContext context, Map<Path, Document> pomMap) {
        Set<Path> processedPoms = new HashSet<>();
        Set<Path> modifiedPoms = new HashSet<>();
        Set<Path> errorPoms = new HashSet<>();

        // Compute all GAVs for inference
        Set<Coordinates> allGAVs = computeAllArtifactCoordinates(context, pomMap);

        for (Map.Entry<Path, Document> entry : pomMap.entrySet()) {

    * 特定の *path operation* に依存関係を宣言した場合は、**それらも実行されます**。
    * ルーターの依存関係が先に実行され、その後に[デコレータ内の `dependencies`](dependencies/dependencies-in-path-operation-decorators.md)、次に通常のパラメータ依存関係が続きます。
    * [`scopes` を伴う `Security` 依存関係](../advanced/security/oauth2-scopes.md) を追加することもできます。
