终于，我们英雄的身份得到了保护！🥷

它还重新声明了 `id: int`。这样我们便与 API 客户端建立了一种**约定**，使他们始终可以期待 `id` 存在并且是一个整数 `int`（永远不会是 `None`）。

/// tip | 提示

确保返回模型始终提供一个值并且始终是 `int`（而不是 `None`）对 API 客户端非常有用，他们可以在这种确定性下编写更简单的代码。

此外，**自动生成的客户端**将拥有更简洁的接口，这样与你的 API 交互的开发者就能更轻松地使用你的 API。😎

`HeroPublic` 中的所有字段都与 `HeroBase` 中的相同，其中 `id` 声明为 `int`（不是 `None`）：

* `id`
* `name`
* `age`

`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。

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

    tests, either. This causes it to fail to find AtomicLongMapTest.

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)
