    **注意：** 我们为主键字段使用 `int | None`，这样在 Python 代码中我们可以在没有 `id`（`id=None`）的情况下创建对象，并假定数据库在保存时会生成它。SQLModel 会理解数据库会提供 `id`，并在数据库模式中将该列定义为非空的 `INTEGER`。详见 [SQLModel 关于主键的文档](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id)。

* `Field(index=True)` 会告诉 SQLModel 应该为此列创建一个 **SQL 索引**，这样在读取按此列过滤的数据时，程序能在数据库中进行更快的查找。
