Django 5.0.4 release notes
==========================

*April 3, 2024*

Django 5.0.4 fixes several bugs in 5.0.3.

Bugfixes
========

* Fixed a bug in Django 5.0 that caused a crash of ``Model.full_clean()`` on
  fields with expressions in ``db_default``. As a consequence,
  ``Model.full_clean()`` no longer validates for empty values in fields with
  ``db_default`` (:ticket:`35223`).

* Fixed a regression in Django 5.0 where the ``AdminFileWidget`` could be
  rendered with two ``id`` attributes on the "Clear" checkbox
  (:ticket:`35273`).

* Fixed a bug in Django 5.0 that caused a migration crash on PostgreSQL 15+
  when adding a partial ``UniqueConstraint`` with ``nulls_distinct``
  (:ticket:`35329`).

* Fixed a crash in Django 5.0 when performing queries involving table aliases
  and lookups on a ``GeneratedField`` of the aliased table (:ticket:`35344`).

* Fixed a bug in Django 5.0 that caused a migration crash when adding a
  ``GeneratedField`` relying on the ``__contains`` or ``__icontains``
  lookups or using a ``Value`` containing a ``"%"`` (:ticket:`35336`).
