And when using `Depends(scope="request")` (the default), the exit code after `yield` is executed after the response is sent.

You can read more about it in the docs for [Dependencies with `yield` - Early exit and `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope).

## 특별한 타입과 검증 { #special-types-and-validation }

`str`, `int`, `float` 등과 같은 일반적인 단일 타입과는 별개로, `str`을 상속하는 더 복잡한 단일 타입을 사용할 수 있습니다.

사용할 수 있는 모든 옵션을 보려면 [Pydantic의 Type Overview](https://docs.pydantic.dev/latest/concepts/types/)를 확인하세요. 다음 장에서 몇 가지 예제를 볼 수 있습니다.

예를 들어 `Image` 모델에는 `url` 필드가 있으므로, 이를 `str` 대신 Pydantic의 `HttpUrl` 인스턴스로 선언할 수 있습니다:

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

* 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。

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`：

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

	}

## Pydantic のモデル { #pydantic-models }

[Pydantic](https://docs.pydantic.dev/) はデータ検証を行うための Python ライブラリです。

データの「形」を属性付きのクラスとして宣言します。

そして、それぞれの属性は型を持ちます。

さらに、いくつかの値を持つクラスのインスタンスを作成すると、その値を検証し、適切な型に変換して（もしそうであれば）すべてのデータを持つオブジェクトを提供してくれます。
