2023-09-12Removed ChoicesMeta.__contains__() for Python 3.12+.Nick Pope
In Python 3.12 it is possible to check containment using member values, not just the members themselves. https://docs.python.org/3/library/enum.html#enum.EnumType.__contains__
2023-09-07Fixed #34791 -- Fixed incorrect Prefetch()'s cache for singly related objects.Maxime Toussaint
Changed the cache name used for singly related objects to be the to_attr parameter passed to a Prefetch object. This fixes issues with checking if values have already been fetched in cases where the Field already has some prefetched value, but not for the same model attr.
2023-09-07Fixed #31300 -- Added GeneratedField model field.Jeremy Nauta
Thanks Adam Johnson and Paolo Melchiorre for reviews. Co-Authored-By: Lily Foote <code@lilyf.org> Co-Authored-By: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2023-09-01Fixed #34803 -- Fixed queryset crash when filtering againts deeply nested ↵willzhao
OuterRef annotations. Thanks Pierre-Nicolas Rigal for the report. Regression in c67ea79aa981ae82595d89f8018a41fcd842e7c9.

2023-08-09Fixed #34586 -- Made QuerySet.create() raise ValueError for reverse ↵Mariana
one-to-many relations.
2023-08-04Fixed #34754 -- Fixed JSONField check constraints validation on NULL values.Simon Charette
The __isnull lookup of JSONField must special case Value(None, JSONField()) left-hand-side in order to be coherent with its convoluted null handling. Since psycopg>=3 offers no way to pass a NULL::jsonb the issue is resolved by optimizing IsNull(Value(None), True | False) to True | False. Regression in 5c23d9f0c32f166c81ecb6f3f01d5077a6084318. Thanks Alexandre Collet for the report.
2023-08-02Removed unneeded escapes in regexes.Mariusz Felisiak
Special characters lose their special meaning inside sets of characters. "-" lose its special meaning if it's placed as the first or last character. Follow up to 7c6b66383da5f9a67142334cd2ed2d769739e8f1.

Regression in dd68af62b2b27ece50d434f6a351877212e15c3f. Thanks Toan Vuong for the report.

2023-07-19Fixed #34717 -- Fixed QuerySet.aggregate() crash when referencing window ↵Simon Charette
functions. Regression in 59bea9efd2768102fc9d3aedda469502c218e9b7. Refs #28477. Thanks younes-chaoui for the report.
2023-07-10Fixed #34698 -- Made QuerySet.bulk_create() retrieve primary keys when ↵Thomas Chaumeny
updating conflicts.
2023-07-07Refs #32433 -- Reallowed calling QuerySet.delete() after distinct().Simon Charette
While values(*field_excluding_pk).distinct() and distinct(*field_excluding_pk) can reduce the number of resulting rows in a way that makes subsequent delete() calls ambiguous standalone .distinct() calls cannot. Since delete() already disallows chain usages with values() the only case that needs to be handled, as originally reported, is when DISTINCT ON is used via distinct(*fields). Refs #32682 which had to resort to subqueries to prevent duplicates in the admin and caused significant performance regressions on MySQL (refs #34639). This partly reverts 6307c3f1a123f5975c73b231e8ac4f115fd72c0d.
2023-06-29Fixed #30382 -- Allowed specifying parent classes in force_insert of ↵Akash Kumar Sen
Model.save().
2023-06-20Refs #34634 -- Fixed creating diamond-shaped MTI objects with ancestors ↵Akash Kumar Sen
inherited from different paths. Co-authored-by: Simon Charette <charette.s@gmail.com>
2023-06-20Fixed #34634 -- Adjusted system check for clashing fields to warn about ↵Akash Kumar Sen
links to common parent for MTI models.
2023-06-19Refs #34517 -- Restored skipping ImageFileField.update_dimension_fields ↵François Freitag
without width/height fields. This avoids reading the image size when the dimensions fields (image_width, image_height) do not exist, as that operation may be expensive. Partially reverts ea53e7c09f1b8864c20c65976bbeaeab77abdaec, that dropped the check for the dimension fields in update_dimension_fields(), because the post_init signal was no longer registered without dimension fields. However, another code path to that function exists: when the ImageFileField is save()d, the name from the storage is setattr()ed on the field, and ImageFileDescriptor calls update_dimension_fields() because the image size might have changed. Keep bailing out early when dimensions are unused. Besides, computing the image dimensions causes to close() the file, resulting in a backward-incompatible change. The test protects against that change.
2023-06-15Fixed #33414 -- Fixed creating diamond-shaped MTI objects for common ↵Akash Kumar Sen
ancestor with primary key that has a default. Co-authored-by: Simon Charette <charette.s@gmail.com>
2023-06-14Refs #32143 -- Removed superflous constraints on excluded query.Simon Charette
The outer query reference is not necessary when alias can be reused and can even be harmful by confusing query planers. Refs #34597.
2023-06-14Refs #32143 -- Adjusted a comment about subquery usage in Query.split_exclude().Simon Charette
2023-06-08Fixed #34604 -- Corrected fallback SQL for n-ary logical XOR.Anders Kaseorg
An n-ary logical XOR Q(…) ^ Q(…) ^ … ^ Q(…) should evaluate to true when an odd number of its operands evaluate to true, not when exactly one operand evaluates to true.
2023-06-01Fixed #34612 -- Fixed QuerySet.only() crash on reverse relationships.Simon Charette
Regression in b3db6c8dcb5145f7d45eff517bcd96460475c879. Thanks Ian Cubitt for the report. This also corrected test_inheritance_deferred2() test which was previously properly defined and marked as an expected failure but was then wrongly adjusted to mask the lack of support for per-alias deferral that was fixed by #21204.
2023-05-31Fixed #34606 -- Fixed Right() function with zero length on Oracle and SQLite.Kacper Wolkiewicz
2023-05-24Fixed #34590 -- Reverted "Refs #33308 -- Improved adapting DecimalField ↵David Sanders

2023-05-17Fixed #34570 -- Silenced noop deferral of many-to-many and GFK.Simon Charette
While deferring many-to-many and GFK has no effect, the previous implementation of QuerySet.defer() ignore them instead of crashing. Regression in b3db6c8dcb5145f7d45eff517bcd96460475c879. Thanks Paco Martínez for the report.
2023-05-16Fixed #34539 -- Restored get_prep_value() call when adapting JSONFields.Julie Rymer
Regression in 5c23d9f0c32f166c81ecb6f3f01d5077a6084318.
