若要查看所有可用選項，請參閱 [Pydantic 的型別總覽](https://docs.pydantic.dev/latest/concepts/types/)。你會在下一章看到一些範例。

例如，在 `Image` 模型中有一個 `url` 欄位，我們可以將其宣告為 Pydantic 的 `HttpUrl`，而不是 `str`：

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

該字串會被檢查是否為有效的 URL，並在 JSON Schema / OpenAPI 中相應註記。

## 具有子模型列表的屬性 { #attributes-with-lists-of-submodels }

你也可以將 Pydantic 模型作為 `list`、`set` 等的子型別使用：
