Если необходимо выполнить частичное обновление, то очень полезно использовать параметр `exclude_unset` в методе `.model_dump()` модели Pydantic.

Например, `item.model_dump(exclude_unset=True)`.

/// info | Информация

В Pydantic v1 метод назывался `.dict()`, в Pydantic v2 он помечен как устаревший (но все еще поддерживается) и переименован в `.model_dump()`.

/// note | 技术细节

`Cookie` 、`Path` 、`Query` 是**兄弟类**，都继承自共用的 `Param` 类。

注意，从 `fastapi` 导入的 `Query`、`Path`、`Cookie` 等对象，实际上是返回特殊类的函数。

///

/// info | 说明

必须使用 `Cookie` 声明 cookie 参数，否则该参数会被解释为查询参数。

## 試してみる

ファイル名が `main.py` である場合、以下の方法でアプリケーションを実行します。

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

ブラウザで <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a> を開きます。
