Vous pouvez utiliser toutes les mêmes fonctionnalités et outils de validation que pour les modèles Pydantic, comme différents types de données et des validations supplémentaires avec `Field()`.

Si vous voulez quelque chose à copier-coller rapidement, n'utilisez pas cet exemple, utilisez le dernier ci-dessous.

在这些情况下，你可以使用**自定义校验函数**，该函数会在正常校验之后应用（例如，在先校验值是 `str` 之后）。

你可以在 `Annotated` 中使用 [Pydantic 的 `AfterValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) 来实现。

/// tip | 提示

Pydantic 还有 [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) 等。🤓

* `Field(primary_key=True)` 会告诉 SQLModel `id` 是 SQL 数据库中的**主键**（你可以在 SQLModel 文档中了解更多关于 SQL 主键的信息）。

    **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)。
