# Body - Fields { #body-fields }

The same way you can declare additional validation and metadata in *path operation function* parameters with `Query`, `Path` and `Body`, you can declare validation and metadata inside of Pydantic models using Pydantic's `Field`.

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

First, you have to import it:

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


/// warning

## `Field`のインポート

まず、以下のようにインポートします:

{* ../../docs_src/body_fields/tutorial001.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。

///

## モデルの属性の宣言

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:

          <type>String</type>
        </field>
        <field>
          <name>version</name>
          <version>4.0.0+</version>
          <required>true</required>
          <description>The current version of the artifact produced by this project.</description>
          <type>String</type>
        </field>
        <field>
          <name>packaging</name>
          <version>4.0.0+</version>

        final Field field2 = UriTypeTest.class.getDeclaredField("testFieldFile");
        final UriType annotation2 = field2.getAnnotation(UriType.class);
