Os exemplos aqui usam `.copy()` para compatibilidade com o Pydantic v1, mas você deve usar `.model_copy()` com o Pydantic v2.

///

Como `stored_item_model.model_copy(update=update_data)`:

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

### Recapitulando as atualizações parciais { #partial-updates-recap }

Resumindo, para aplicar atualizações parciais você pode:

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

### Pydanticの`update`パラメータ

ここで、`.copy()`を用いて既存のモデルのコピーを作成し、`update`パラメータに更新するデータを含む`dict`を渡すことができます。

`stored_item_model.copy(update=update_data)`のように:

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

### 部分的更新のまとめ

まとめると、部分的な更新を適用するには、次のようにします:

* (オプションで)`PUT`の代わりに`PATCH`を使用します。
* 保存されているデータを取得します。
* そのデータをPydanticモデルにいれます。
