然后在 `/docs` UI 中，你能够看到 **FastAPI** 会用这些**模型**来**记录** API，并且还会用它们来**序列化**和**验证**数据。

## 使用多个模型更新应用 { #update-the-app-with-multiple-models }

现在让我们稍微**重构**一下这个应用，以提高**安全性**和**多功能性**。

如果你查看之前的应用程序，你可以在 UI 界面中看到，到目前为止，它允许客户端决定要创建的 `Hero` 的 `id`。😱

			// Thus, setup the regFileReader again after merging PAX headers.
			if err := tr.handleRegularFile(hdr); err != nil {
				return nil, err
