We are doing it here to demonstrate how **FastAPI** handles scopes declared at different levels.

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,141,172] *}

/// info | Technical Details

`Security` is actually a subclass of `Depends`, and it has just one extra parameter that we'll see later.

フォームを使うためには、まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

たとえば、`pip install python-multipart`のように。

## `Form`のインポート

`fastapi`から`Form`をインポートします:

{* ../../docs_src/request_forms/tutorial001.py hl[1] *}

## `Form`のパラメータの定義

`Body`や`Query`の場合と同じようにフォームパラメータを作成します:

{* ../../docs_src/request_forms/tutorial001.py hl[7] *}

# Тіло запиту - Вкладені моделі

З **FastAPI** Ви можете визначати, перевіряти, документувати та використовувати моделі, які можуть бути вкладені на будь-яку глибину (завдяки Pydantic).

## Поля списку

Ви можете визначити атрибут як підтип. Наприклад, Python-список (`list`):

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

Це зробить `tags` списком, хоча не визначається тип елементів списку.
