Django 1.8.2 release notes
==========================

*Under development*

Django 1.8.2 fixes several bugs in 1.8.1.

Bugfixes
========

* Fixed check for template engine alias uniqueness (:ticket:`24685`).

* Fixed crash when reusing the same ``Case`` instance in a query
  (:ticket:`24752`).

* Corrected join promotion for ``Case`` expressions. For example, annotating a
  query with a  ``Case`` expression could unexpectedly filter out results
  (:ticket:`24766`).

* Fixed incorrect GROUP BY clause generation on MySQL when the query's model
  has a self-referential foreign key (:ticket:`24748`).

* Implemented ``ForeignKey.get_db_prep_value()`` so that ``ForeignKey``\s
  pointing to :class:`~django.db.models.UUIDField` and inheritance on models
  with ``UUIDField`` primary keys work correctly (:ticket:`24698`,
  :ticket:`24712`).

[1.8.x] Used a simpler word that doesn't fail the spelling checker. Backport of 17b1f7886c276086bbb471c0d5c3b510319f8bbb from master 2015-05-04 14:55:03 +00:00			* Fixed check for template engine alias uniqueness (:ticket:`24685`).
[1.8.x] Fixed #24752 -- query crash when reusing Case expressions Case expressions weren't copied deep enough (self.cases list was reused resulting in an error). Backport of 7b05d2fdaed582662d8f79130932f600f4f966a0 from master 2015-05-05 11:11:58 +00:00

			* Corrected join promotion for ``Case`` expressions. For example, annotating a

			(:ticket:`24766`).
[1.8.x] Fixed #24748 -- Fixed incorrect GROUP BY on MySQL in some queries When the query's model had a self-referential foreign key, the compiler.get_group_by() code incorrectly used the self-referential foreign key's column (for example parent_id) as GROUP BY clause when it should have used the model's primary key column (id).
