## 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。

/// note | "技術詳細"

実際には次に見る`Query`や`Path`などは、共通の`Param`クラスのサブクラスのオブジェクトを作成しますが、それ自体はPydanticの`FieldInfo`クラスのサブクラスです。

また、Pydanticの`Field`は`FieldInfo`のインスタンスも返します。

7. Aqui o `response_model` está usando uma anotação de tipo de uma lista de dataclasses `Author`.

    Novamente, você pode combinar `dataclasses` com anotações de tipo padrão.

8. Note que esta *função de operação de rota* usa `def` regular em vez de `async def`.

    Como sempre, no FastAPI você pode combinar `def` e `async def` conforme necessário.

```Python hl_lines="3  17"
{!> ../../docs_src/path_operation_configuration/tutorial001.py!}
```

Você também pode instalar parte por parte.

Isso é provavelmente o que você faria quando você quisesse lançar sua aplicação em produção:

```
pip install fastapi
