* 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：

<img src="/img/tutorial/body/image01.png">

并且，还会用于需要它们的每个*路径操作*的 API 文档中：

Você pode declarar informação extra em `Field`, `Query`, `Body`, etc. E isso será incluído no JSON Schema gerado.

Você irá aprender mais sobre adicionar informações extras posteriormente nessa documentação, quando estiver aprendendo a declarar exemplos.

/// warning | Atenção

Chaves extras passadas para `Field` também estarão presentes no schema OpenAPI resultante da sua aplicação.

### Сгенерируйте схему OpenAPI { #generate-the-openapi-schema }

Затем используйте ту же вспомогательную функцию для генерации схемы OpenAPI внутри функции `custom_openapi()`:
