Django 1.8.3 release notes
|
||
==========================
|
||
|
||
*Under development*
|
||
|
||
Django 1.8.3 fixes several bugs in 1.8.2.
|
||
|
||
Also, ``django.utils.deprecation.RemovedInDjango20Warning`` was renamed to
|
||
``RemovedInDjango110Warning`` as the version roadmap was revised to 1.9, 1.10,
|
||
1.11 (LTS), 2.0 (drops Python 2 support). For backwards compatibility,
|
||
``RemovedInDjango20Warning`` remains as an importable alias.
|
||
|
||
Bugfixes
|
||
========
|
||
|
||
* Fixed ``BaseRangeField.prepare_value()`` to use each ``base_field``’s
|
||
``prepare_value()`` method (:ticket:`24841`).
|
||
|
||
* Fixed crash during :djadmin:`makemigrations` if a migrations module either
|
||
is missing ``__init__.py`` or is a file (:ticket:`24848`).
|
||
|
||
* Fixed ``QuerySet.exists()`` returning incorrect results after annotation with
|
||
``Count()`` (:ticket:`24835`).
|
||
|
||
* Corrected ``HStoreField.has_changed()`` (:ticket:`24844`).
|
||
|
||
* Reverted an optimization to the CSRF template context processor which caused
|
||
a regression (:ticket:`24836`).
|
||
|
||
* Fixed a regression which caused template context processors to overwrite
|
||
variables set on a ``RequestContext`` after it's created (:ticket:`24847`).
|
||
|
||
* Prevented the loss of ``null``/``not null`` column properties during field
|
||
renaming of MySQL databases (:ticket:`24817`).
|
||
|
||
* Fixed a crash when using a reverse one-to-one relation in
|
||
``ModelAdmin.list_display`` (:ticket:`24851`).
|
||
|
||
* Fixed quoting of SQL when renaming a field to ``AutoField`` in PostgreSQL
|
||
(:ticket:`24892`).
|
||
|
||
* Fixed lack of unique constraint when changing a field from
|
||
``primary_key=True`` to ``unique=True`` (:ticket:`24893`).
|
||
|
||
* Fixed queryset pickling when using ``prefetch_related()`` after deleting
|
||
objects (:ticket:`24831`).
|
||
|
||
* Allowed using ``choices`` longer than 1 day with ``DurationField``
|
||
(:ticket:`24897`).
|
||
|
||
* Fixed a crash when loading squashed migrations from two apps with a
|
||
dependency between them, where the dependent app's replaced migrations are
|
||
partially applied (:ticket:`24895`).
|
||
|
||
* Fixed recording of applied status for squashed (replacement) migrations
|
||
(:ticket:`24628`).
|
||
|
||
* Fixed queryset annotations when using ``Case`` expressions with ``exclude()``
|
||
(:ticket:`24833`).
|
||
|
||
* Corrected join promotion for multiple ``Case`` expressions. Annotating a
|
||
query with multiple ``Case`` expressions could unexpectedly filter out
|
||
results (:ticket:`24924`).
|
||
|
||
* Fixed usage of transforms in subqueries (:ticket:`24744`).
|
||
|
||
* Fixed ``SimpleTestCase.assertRaisesMessage()`` on Python 2.7.10
|
||
(:ticket:`24903`).
|
||
|
||
* Provided better backwards compatibility for the ``verbosity`` argument in
|
||
``optparse`` management commands by casting it to an integer
|
||
(:ticket:`24769`).
|
||
|
||
* Fixed ``prefetch_related()`` on databases other than PostgreSQL for models
|
||
using UUID primary keys (:ticket:`24912`).
|
||
|
||
* Fixed removing ``unique_together`` constraints on MySQL (:ticket:`24972`).
|
||
|
||
* Fixed crash when uploading images with MIME types that Pillow doesn't detect,
|
||
such as bitmap, in ``forms.ImageField`` (:ticket:`24948`).
|
||
|
||
* Fixed a regression when deleting a model through the admin that has a
|
||
``GenericRelation`` with a ``related_query_name`` (:ticket:`24940`).
|
||
|
||
* Reallowed non-ASCII values for ``ForeignKey.related_name`` on Python 3 by
|
||
fixing the false positive system check (:ticket:`25016`).
|
||
|
||
* Fixed inline forms that use a parent object that has a ``UUIDField`` primary
|
||
key and a child object that has an ``AutoField`` primary key
|
||
(:ticket:`24958`).
|
||
|
||
* Fixed a regression in the ``unordered_list`` template filter on certain
|
||
inputs (:ticket:`25031`).
