## Pydantic `Settings` { #pydantic-settings }

Glücklicherweise bietet Pydantic ein großartiges Werkzeug zur Verarbeitung dieser Einstellungen, die von Umgebungsvariablen stammen, mit [Pydantic: Settings Management](https://docs.pydantic.dev/latest/concepts/pydantic_settings/).

### `pydantic-settings` installieren { #install-pydantic-settings }

        Collections.addAll(trustedCertificates, *platformTrustManager.acceptedIssuers)
      }

`images` 키가 이제 이미지 객체 리스트를 갖는지 주목하세요.

        "url": "http://example.com/baz.jpg",

再一次，仅仅进行这样的声明，你将通过 **FastAPI** 获得：

* 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 { #special-types-and-validation }

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 [Pydantic 的类型概览](https://docs.pydantic.dev/latest/concepts/types/)。你将在下一章节中看到一些示例。

有時你需要做一些上述參數無法處理的「自訂驗證」。

這種情況下，你可以使用「自訂驗證函式」，它會在一般驗證之後套用（例如先確認值是 `str` 之後）。

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

/// tip | 提示

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