然后再用它生成一个只含已设置（在请求中所发送）数据，且省略了默认值的 `dict`：

{* ../../docs_src/body_updates/tutorial002.py hl[34] *}

### 使用 Pydantic 的 `update` 参数

接下来，用 `.copy()` 为已有模型创建调用 `update` 参数的副本，该参数为包含更新数据的 `dict`。

例如，`stored_item_model.copy(update=update_data)`：

{* ../../docs_src/body_updates/tutorial002.py hl[35] *}

### 更新部分数据小结

简而言之，更新部分数据应：

* 使用 `PATCH` 而不是 `PUT` （可选，也可以用 `PUT`）；
* 提取存储的数据；

/// info | Информация

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

Примеры здесь используют `.copy()` для совместимости с Pydantic v1, но если вы можете использовать Pydantic v2, лучше используйте `.model_copy()`.
