此处，在应用程序启动事件中，我们创建了表。

而对于生产环境，您可能会用一个能够在启动应用程序之前运行的迁移脚本。🤓

/// tip

SQLModel 将会拥有封装 Alembic 的迁移工具，但目前您可以直接使用 <a href="https://alembic.sqlalchemy.org/en/latest/" class="external-link" target="_blank">Alembic</a>。

### 创建 Hero 类

因为每个 SQLModel 模型同时也是一个 Pydantic 模型，所以您可以在与 Pydantic 模型相同的**类型注释**中使用它。

例如，如果您声明一个类型为 `Hero` 的参数，它将从 **JSON 主体**中读取数据。
