Django 2.2.7 release notes
==========================

*November 4, 2019*

Django 2.2.7 fixes several bugs in 2.2.6.

Bugfixes
========

* Fixed a crash when using a ``contains``, ``contained_by``, ``has_key``,
  ``has_keys``, or ``has_any_keys`` lookup on
  ``django.contrib.postgres.fields.JSONField``, if the right or left hand
  side of an expression is a key transform (:ticket:`30826`).

* Prevented :option:`migrate --plan` from showing that ``RunPython`` operations
  are irreversible when ``reverse_code`` callables don't have docstrings or
  when showing a forward migration plan (:ticket:`30870`).

* Fixed migrations crash on PostgreSQL when adding an
  :class:`~django.db.models.Index` with fields ordering and
  :attr:`~.Index.opclasses` (:ticket:`30903`).

* Restored the ability to override
  :meth:`~django.db.models.Model.get_FOO_display` (:ticket:`30931`).
