これでヒーローの正体は守られます！🥷

また、`id: int` を再宣言します。これにより、API クライアントとの間で「常に `id` が存在し、`int` である（`None` にはならない）」という契約を結びます。

/// tip | 豆知識

戻り値のモデルで、値が常に存在し常に `int`（`None` ではない）であることを保証すると、API クライアント側のコードははるかにシンプルに書けます。

加えて、自動生成クライアントのインターフェースも簡潔になり、あなたの API とやり取りする開発者体験が向上します。😎

///

`HeroPublic` のフィールドは `HeroBase` と同じで、`id` は `int`（`None` ではない）として宣言されます:

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

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`
