    !!! tip "팁"

まず、以下のようにインポートします:

```Python hl_lines="4"
{!../../../docs_src/body_fields/tutorial001.py!}
```

!!! 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:

```Python hl_lines="11 12 13 14"
{!../../../docs_src/body_fields/tutorial001.py!}
```

`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。

## Импорт `Field`

Сначала вы должны импортировать его:

    ```Python hl_lines="2"
    {!> ../../../docs_src/body_fields/tutorial001_py310.py!}
    ```

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001.py!}
    ```

!!! warning "Внимание"

    ```Python hl_lines="4"
    {!> ../../../docs_src/body_fields/tutorial001_an.py!}
    ```

=== "Python 3.10+ non-Annotated"

    !!! tip
        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="2"
    {!> ../../../docs_src/body_fields/tutorial001_py310.py!}
    ```

    !!! tip

```Python hl_lines="4"
{!../../../docs_src/body_fields/tutorial001.py!}
```

!!! warning "Aviso"
    Note que `Field` é importado diretamente do `pydantic`, não do `fastapi` como todo o resto (`Query`, `Path`, `Body`, etc).

## Declare atributos do modelo

Você pode então utilizar `Field` com atributos do modelo:

```Python hl_lines="11-14"
{!../../../docs_src/body_fields/tutorial001.py!}
```
