就像你可以在「路徑操作函式 (path operation function)」的參數中用 `Query`、`Path` 和 `Body` 宣告額外的驗證與中繼資料一樣，你也可以在 Pydantic 模型中使用 Pydantic 的 `Field` 來宣告驗證與中繼資料。

## 匯入 `Field` { #import-field }

首先，你需要匯入它：

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


/// warning

請注意，`Field` 是直接從 `pydantic` 匯入的，不像其他（如 `Query`、`Path`、`Body` 等）是從 `fastapi` 匯入。

///

## 宣告模型屬性 { #declare-model-attributes }

# Body - Alanlar { #body-fields }

`Query`, `Path` ve `Body` ile *path operation function* parametrelerinde ek doğrulama ve metadata tanımlayabildiğiniz gibi, Pydantic modellerinin içinde de Pydantic'in `Field`'ını kullanarak doğrulama ve metadata tanımlayabilirsiniz.

## `Field`'ı import edin { #import-field }

Önce import etmeniz gerekir:

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

/// warning | Uyarı

        BooleanQuery.Builder boolQueryBuilder = new BooleanQuery.Builder();
        TermQuery termQuery1 = new TermQuery(new Term("field1", "value1"));
        TermQuery termQuery2 = new TermQuery(new Term("field2", "value2"));
        TermQuery termQuery3 = new TermQuery(new Term("field3", "value3"));

        boolQueryBuilder.add(termQuery1, BooleanClause.Occur.MUST);

# 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。

///

# Corpo - Campos { #body-fields }

Da mesma forma que você pode declarar validações adicionais e metadados nos parâmetros de uma *função de operação de rota* com `Query`, `Path` e `Body`, você pode declarar validações e metadados dentro de modelos do Pydantic usando `Field` do Pydantic.

## Importe `Field` { #import-field }

Primeiro, você tem que importá-lo:

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