• Polymorphic serializer validated data is now updated with the child data by @bckohan in https://github.com/jazzband/django-polymorphic/pull/841

Full Changelog: https://github.com/jazzband/django-polymorphic/compare/v4.10.0...v4.10.1

This release is primarily an integrations release. Many tests were added for the documented intergrations and a few bugs were fixed. Some warnings were converted to system checks. The two most notable changes are:

• The django-rest-polymorphic package is now part of django-polymorphic. (Thank you @denisorehovsky!!)

• In queries that need content types that are not cached those fetches are now embedded as subqueries. This reduces the total number of queries needed but most importantly it eliminates a class of errors that could happen if Manager/QuerySet methods that should not but do generate database queries are called before models are loaded (e.g. get_queryset()).

[!TIP] All you need to do to drop your dependency on django-rest-polymorphic is to update the import path for PolymorphicSerializer from rest_polymorphic.serializers to polymorphic.contrib.drf.serializers

ORM Bug Fix Release

This release fixes a number of long standing bugs with respect to query behavior and inheritance. Most notably:

1. The queryset iterator and get_real_instance will attempt to fetch the correct type even if the polymorphic content type id is wrong. This can happen in legitimate work flows in signal handling during deletes as the child tables are deleted in order.
2. The parent/child table forward/reverse onetoone fields are now implemented as descriptors subclassed from the base django descriptors. This fixes a number of bugs wrt to custom primary keys and primary keys of different values within one model's set of parent/child tables.
