/// warning | 경고

`Field`는 다른 것들처럼 (`Query`, `Path`, `Body` 등) `fastapi`에서가 아닌 `pydantic`에서 바로 임포트 되는 점에 주의하세요.

///

## 모델 어트리뷰트 선언 { #declare-model-attributes }

그 다음 모델 어트리뷰트와 함께 `Field`를 사용할 수 있습니다:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

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

String’in geçerli bir URL olup olmadığı kontrol edilir ve JSON Schema / OpenAPI’de de buna göre dokümante edilir.

## Alt modellerden oluşan list’lere sahip attribute’lar { #attributes-with-lists-of-submodels }

Pydantic modellerini `list`, `set` vb. tiplerin alt tipi olarak da kullanabilirsiniz:

{* ../../docs_src/body_nested_models/tutorial006_py310.py hl[18] *}

                compositeConfiguration.setCanBeResolved(false);
                compositeConfiguration.getAttributes().attribute(ARTIFACT_FORMAT, ArtifactTypeDefinition.DIRECTORY_TYPE);
                compositeConfiguration.getAttributes().attribute(Attribute.of("composite", Boolean.class), true);
                sub.getArtifacts().add(COMPOSITE_CONFIGURATION_NAME, distributionArchive.getArchiveTask());

      throws IOException {
    Manifest manifest = new Manifest();
    // Without version, the manifest is silently ignored. Ugh!
    manifest.getMainAttributes().put(Attributes.Name.MANIFEST_VERSION, "1.0");
    manifest.getMainAttributes().put(Attributes.Name.CLASS_PATH, jarFile.getName());

    Closer closer = Closer.create();
    try {
      FileOutputStream fileOut = closer.register(new FileOutputStream(jarFile));

La chaîne sera vérifiée comme URL valide et documentée comme telle dans JSON Schema / OpenAPI.

## Attributs avec des listes de sous-modèles { #attributes-with-lists-of-submodels }

Vous pouvez également utiliser des modèles Pydantic comme sous-types de `list`, `set`, etc. :

            ridWithAttribute.rid = 100;
            ridWithAttribute.attributes = 200;
