The LIKE operator wildcard generated for contains, startswith, endswith and their case-insensitive variant lookups was conflicting with parameter interpolation on CREATE constraint statement execution. Ideally we'd delegate parameters interpolation in DDL statements on backends that support it but that would require backward incompatible changes to the Index and Constraint SQL generating methods. Thanks David Sanders for the report.

Django 2.2.1 release notes
|
|
==========================
|
|
|
|
*Expected May 1, 2019*
|
|
|
|
Django 2.2.1 fixes several bugs in 2.2.
|
|
|
|
Bugfixes
|
|
========
|
|
|
|
* Fixed a regression in Django 2.1 that caused the incorrect quoting of
|
|
database user password when using :djadmin:`dbshell` on Oracle
|
|
(:ticket:`30307`).
|
|
|
|
* Added compatibility for ``psycopg2`` 2.8 (:ticket:`30331`).
|
|
|
|
* Fixed a regression in Django 2.2 that caused a crash when loading the
|
|
template for the technical 500 debug page (:ticket:`30324`).
|
|
|
|
* Fixed crash of ``ordering`` argument in
|
|
:class:`~django.contrib.postgres.aggregates.ArrayAgg` and
|
|
:class:`~django.contrib.postgres.aggregates.StringAgg` when it contains an
|
|
expression with params (:ticket:`30332`).
|
|
|
|
* Fixed a regression in Django 2.2 that caused a single instance fast-delete
|
|
to not set the primary key to ``None`` (:ticket:`30330`).
|
|
|
|
* Prevented :djadmin:`makemigrations` from generating infinite migrations for
|
|
check constraints and partial indexes when ``condition`` contains
|
|
a :class:`~python:range` object (:ticket:`30350`).
|
|
|
|
* Reverted an optimization in Django 2.2 (:ticket:`29725`) that caused the
|
|
inconsistent behavior of ``count()`` and ``exists()`` on a reverse
|
|
many-to-many relationship with a custom manager (:ticket:`30325`).
|
|
|
|
* Fixed a regression in Django 2.2 where
|
|
:class:`~django.core.paginator.Paginator` crashes if ``object_list`` is
|
|
a queryset ordered or aggregated over a nested ``JSONField`` key transform
|
|
(:ticket:`30335`).
|
|
|
|
* Fixed a regression in Django 2.2 where ``IntegerField`` validation of
|
|
database limits crashes if ``limit_value`` attribute in a custom validator is
|
|
callable (:ticket:`30328`).
|
|
|
|
* Fixed a regression in Django 2.2 where
|
|
:class:`~django.contrib.postgres.search.SearchVector` generates SQL that is
|
|
not indexable (:ticket:`30385`).
|
|
|
|
* Fixed a regression in Django 2.2 that caused an exception to be raised when
|
|
a custom error handler could not be imported (:ticket:`30318`).
|
|
|
|
* Relaxed the system check added in Django 2.2 for the admin app's dependencies
|
|
to reallow use of
|
|
:class:`~django.contrib.sessions.middleware.SessionMiddleware` subclasses,
|
|
rather than requiring :mod:`django.contrib.sessions` to be in
|
|
:setting:`INSTALLED_APPS` (:ticket:`30312`).
|
|
|
|
* Increased the default timeout when using ``Watchman`` to 5 seconds to prevent
|
|
falling back to ``StatReloader`` on larger projects and made it customizable
|
|
via the ``DJANGO_WATCHMAN_TIMEOUT`` environment variable (:ticket:`30361`).
|
|
|
|
* Fixed a regression in Django 2.2 that caused a crash when migrating
|
|
permissions for proxy models if the target permissions already existed. For
|
|
example, when a permission had been created manually or a model had been
|
|
migrated from concrete to proxy (:ticket:`30351`).
|
|
|
|
* Fixed a regression in Django 2.2 that caused a crash of :djadmin:`runserver`
|
|
when URLConf modules raised exceptions (:ticket:`30323`).
|
|
|
|
* Fixed a regression in Django 2.2 where changes were not reliably detected by
|
|
auto-reloader when using ``StatReloader`` (:ticket:`30323`).
|
|
|
|
* Fixed a migration crash on Oracle and PostgreSQL when adding a check
|
|
constraint with a ``contains``, ``startswith``, or ``endswith`` lookup (or
|
|
their case-insensitive variant) (:ticket:`30408`).
