## Anwendungsfall { #use-case }

Beginnen wir mit einem Beispiel-**Anwendungsfall** und schauen uns dann an, wie wir ihn mit dieser Methode implementieren können.

Stellen wir uns vor, Sie verfügen über einige **Modelle für maschinelles Lernen**, die Sie zur Bearbeitung von Requests verwenden möchten. 🤖

             <font color="#3465A4">__init__.py</font> files

* 把接收的数据赋值给参数 `item`。
    * 因为你把函数中的参数类型声明为 `Item`，所以还能获得所有属性及其类型的编辑器支持（补全等）。
* 为你的模型生成 [JSON Schema](https://json-schema.org) 定义，如果对你的项目有意义，还可以在其他地方使用它们。
* 这些 schema 会成为生成的 OpenAPI Schema 的一部分，并被自动文档的 <abbr title="User Interfaces - 用户界面">UIs</abbr> 使用。

## 自动文档 { #automatic-docs }

你的模型的 JSON Schema 会成为生成的 OpenAPI Schema 的一部分，并显示在交互式 API 文档中：
