# 请求体 - 嵌套模型

使用 **FastAPI**，你可以定义、校验、记录文档并使用任意深度嵌套的模型（归功于Pydantic）。

## List 字段

你可以将一个属性定义为拥有子元素的类型。例如 Python `list`：

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

这将使 `tags` 成为一个由元素组成的列表。不过它没有声明每个元素的类型。

## 具有子类型的 List 字段

但是 Python 有一种特定的方法来声明具有子类型的列表：

### 从 typing 导入 `List`

首先，从 Python 的标准库 `typing` 模块中导入 `List`：

{* ../../docs_src/body_nested_models/tutorial002.py hl[1] *}

            <property name="checkEmptyJavadoc" value="true"/>
        </module>

        <module name="JavadocType">
            <property name="scope" value="protected"/>
            <!-- Allow the use of unrecognized tags like @apiNote -->
            <property name="allowUnknownTags" value="true"/>
        </module>

        <!-- TODO - switch this on -->
        <!--<module name="JavadocMethod">-->
