"price": 3,
    "description": None,
}
```

comme il n’inclut pas l’attribut déjà enregistré « tax »: 20.2, le modèle d’entrée prendrait la valeur par défaut « tax »: 10.5.

Et les données seraient enregistrées avec cette « nouvelle » « tax » de 10.5.

## Effectuer des mises à jour partielles avec `PATCH` { #partial-updates-with-patch }

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

이미 저장된 속성 `"tax": 20.2`가 포함되어 있지 않기 때문에, 입력 모델은 `"tax": 10.5`라는 기본값을 사용하게 됩니다.

그리고 데이터는 그 “새로운” `tax` 값 `10.5`로 저장됩니다.

## `PATCH`로 부분 업데이트하기 { #partial-updates-with-patch }

[HTTP `PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH) 작업을 사용해 데이터를 *부분적으로* 업데이트할 수도 있습니다.

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (or `str | None = None` in Python 3.10) has a default of `None`.
* `tax: float = 10.5` has a default of `10.5`.
* `tags: List[str] = []` has a default of an empty list: `[]`.

but you might want to omit them from the result if they were not actually stored.

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (ou `str | None = None` no Python 3.10) tem um padrão de `None`.
* `tax: float = 10.5` tem um padrão de `10.5`.
* `tags: List[str] = []` tem um padrão de uma lista vazia: `[]`.

mas você pode querer omiti-los do resultado se eles não foram realmente armazenados.

            }

            @Override
            public int getLtrWindowSize() {
                return 150;
            }
        });

        RescorerBuilder<?> result3 = ltrQueryRescorer.evaluate(params);
        assertNotNull(result3);
        assertEquals(150, ((QueryRescorerBuilder) result3).windowSize().intValue());
    }

這表示，如果你想用 `PUT` 並在 body 中包含以下內容來更新項目 `bar`：

```Python
{
    "name": "Barz",
    "price": 3,
    "description": None,
}
```

由於這裡沒有包含已儲存的屬性 `"tax": 20.2`，輸入的模型會採用預設值 `"tax": 10.5`。

最終資料會以這個「新的」 `tax` 值 `10.5` 被儲存。

## 使用 `PATCH` 進行部分更新 { #partial-updates-with-patch }

你也可以使用 [HTTP `PATCH`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH) 操作來進行*部分*更新。

這表示你只需傳送想要更新的資料，其餘保持不變。
