### Avertissement concernant le remplacement { #warning-about-replacing }

Cela signifie que si vous souhaitez mettre à jour l’élément `bar` avec `PUT` et un corps contenant :

```Python
{
    "name": "Barz",
    "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.

`PUT` 用於接收應該取代現有資料的資料。

### 關於取代的警告 { #warning-about-replacing }

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。
