# Django 5.0.4 release notes

*April 3, 2024*

Django 5.0.4 fixes several bugs in 5.0.3.

## Poprawki błędów

- 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` ([#35223](https://code.djangoproject.com/ticket/35223)).
- Fixed a regression in Django 5.0 where the `AdminFileWidget` could be
  rendered with two `id` attributes on the „Clear” checkbox
  ([#35273](https://code.djangoproject.com/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`
  ([#35329](https://code.djangoproject.com/ticket/35329)).
- Fixed a crash in Django 5.0 when performing queries involving table aliases
  and lookups on a `GeneratedField` of the aliased table ([#35344](https://code.djangoproject.com/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 `"%"` ([#35336](https://code.djangoproject.com/ticket/35336)).
