<a href="https://docs.pydantic.dev/latest/concepts/types/#unions" class="external-link" target="_blank">`Union`</a>을 정의할때는 더 구체적인 타입을 먼저 포함하고, 덜 구체적인 타입을 그 뒤에 나열해야합니다. 아래 예제에서는 `Union[PlaneItem, CarItem]` 를 보면, 더 구체적인 `PlaneItem`이 `CarItem`보다 앞에 위치합니다.

* MinIO doesn't currently support PFX certificates.

### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh

        injectPluginDeclarationFromProject(plugin, project);

        // If there is no version to be found then we need to look in the repository metadata for
        // this plugin and see what's specified as the latest release.
        //
        if (plugin.getVersion() == null) {
            resolvePluginVersion(plugin, session, project);
        }

        return pluginManager.getMojoDescriptor(

//// tab | Pydantic v2

В Pydantic версии 2 вы будете использовать атрибут `model_config`, который принимает `dict`, как описано в <a href="https://docs.pydantic.dev/latest/api/config/" class="external-link" target="_blank">Документации Pydantic: Конфигурация</a>.

* 对被嵌入的模型也适用的编辑器支持（自动补全等）
* 数据转换
* 数据校验
* 自动生成文档

## 特殊的类型和校验

除了普通的单一值类型（如 `str`、`int`、`float` 等）外，你还可以使用从 `str` 继承的更复杂的单一值类型。

要了解所有的可用选项，请查看关于 <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">来自 Pydantic 的外部类型</a> 的文档。你将在下一章节中看到一些示例。

例如，在 `Image` 模型中我们有一个 `url` 字段，我们可以把它声明为 Pydantic 的 `HttpUrl`，而不是 `str`：
