# PrimaryKeyListSerializer

## Overview

Validates a ``pks`` body field containing a non-empty list of primary keys.

Without ``model``, each entry must be an integer. With ``model``, each entry converts through
that model's primary key field, as :class:`ModelPrimaryKeyValueField` describes. A model with
an integer primary key keeps the integer check and its error message.
