`PUT` ⚙️ 📨 💽 👈 🔜 ❎ ♻ 💽.

### ⚠ 🔃 ❎

👈 ⛓ 👈 🚥 👆 💚 ℹ 🏬 `bar` ⚙️ `PUT` ⏮️ 💪 ⚗:

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

↩️ ⚫️ 🚫 🔌 ⏪ 🏪 🔢 `"tax": 20.2`, 🔢 🏷 🔜 ✊ 🔢 💲 `"tax": 10.5`.

& 📊 🔜 🖊 ⏮️ 👈 "🆕" `tax` `10.5`.

////

`PUT` используется для получения данных, которые должны полностью заменить существующие данные.

### Предупреждение о замене

Это означает, что если вы хотите обновить элемент `bar`, используя `PUT` с телом, содержащим:

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

поскольку оно не включает уже сохраненный атрибут `"tax": 20.2`, входная модель примет значение по умолчанию `"tax": 10.5`.

```Python hl_lines="30-35"
{!../../docs_src/body_updates/tutorial001.py!}
```

`PUT` 用于接收替换现有数据的数据。

### 关于更新数据的警告

用 `PUT` 把数据项 `bar` 更新为以下内容时：

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

因为上述数据未包含已存储的属性 `"tax": 20.2`，新的输入模型会把 `"tax": 10.5` 作为默认值。

因此，本次操作把 `tax` 的值「更新」为 `10.5`。

## 用 `PATCH` 进行部分更新
