# NestedMultipartMixin

## Overview

Accept object saves with JSON multipart fields and a file-path manifest.

Replace DRF's standard multipart parser while retaining other configured
parsers. Requests without a manifest keep DRF's existing form behavior.
Place this mixin before a DRF view or viewset in its inheritance list.

## `get_parsers` {#get_parsers}

Use the nested parser wherever the standard multipart parser is enabled.
