## 深度嵌套模型

你可以定义任意深度的嵌套模型：

{* ../../docs_src/body_nested_models/tutorial007_py310.py hl[7,12,18,21,25] *}

/// info

请注意 `Offer` 拥有一组 `Item` 而反过来 `Item` 又是一个可选的 `Image` 列表是如何发生的。

///

## 纯列表请求体

```JSON
{
    "name": "Foo",
    "price": 50.2
}
```

/// info

FastAPI 通过 Pydantic 模型的 `.dict()` 配合 <a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">该方法的 `exclude_unset` 参数</a> 来实现此功能。

///

/// info

你还可以使用：

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

As the type, put `list`.

As the list is a type that contains some internal types, you put them in square brackets:

{* ../../docs_src/python_types/tutorial006_py39.py hl[1] *}

/// info

Those internal types in the square brackets are called "type parameters".

In this case, `str` is the type parameter passed to `list`.

## Usa la dependencia { #use-the-dependency }

Entonces podemos usar la dependencia con:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

/// info | Información

Fíjate que solo estamos declarando una dependencia en la *path operation function*, `query_or_cookie_extractor`.
