2023-12-29Fixed #35064 -- Fixed Window(order_by) crash with DecimalFields on SQLite.Simon Charette
This avoids cast of Window(order_by) for DecimalFields on SQLite. This was achieved by piggy-backing ExpressionList which already implements a specialized as_sqlite() method to override the inherited behaviour of Func through SQLiteNumericMixin. Refs #31723. Thanks Quoates for the report.
2023-12-23Fixed #35050 -- Fixed prefixing field names in FilteredRelation().David Wobrock
Thanks Mark Zorn for the report. Regression in 59f475470494ce5b8cbff816b1e5dafcbd10a3a3.
2023-12-16Fixed #35042 -- Fixed a count() crash on combined queries.Simon Charette
Regression in 59bea9efd2768102fc9d3aedda469502c218e9b7. Thanks Marcin for the report.
2023-12-12Fixed #34013 -- Added QuerySet.order_by() support for annotation transforms.Simon Charette
Thanks Eugene Morozov and Ben Nace for the reports.
2023-12-12Fixed #35018 -- Fixed migrations crash on GeneratedField with BooleanField ↵Mariusz Felisiak
as output_field on Oracle < 23c. Thanks Václav Řehák for the report. Regression in f333e3513e8bdf5ffeb6eeb63021c230082e6f95.
2023-12-08Fixed #35019 -- Fixed save() on models with both GeneratedFields and ↵Sarah Boyce
ForeignKeys. Thanks Deb Kumar Das for the report. Regression in f333e3513e8bdf5ffeb6eeb63021c230082e6f95.
2023-12-07Fixed #35024 -- Fixed model instance creation crash on ↵Mariusz Felisiak
GeneratedField.output_field with backend converters. Regression in d9de74141e8a920940f1b91ed0a3ccb835b55729. This is a long standing issue, however it caused a crash of GeneratedFields for all output fields that have backend-specific converters when the RETURNING clause is not supported (MySQL and SQLite < 3.35). That's why severity was exacerbated.

2023-11-23Fixed #34987 -- Fixed queryset crash when mixing aggregate and window ↵Simon Charette
annotations. Regression in f387d024fc75569d2a4a338bfda76cc2f328f627. Just like `OrderByList` the `ExpressionList` expression used to wrap `Window.partition_by` must implement `get_group_by_cols` to ensure the necessary grouping when mixing window expressions with aggregate annotations is performed against the partition members and not the partition expression itself. This is necessary because while `partition_by` is implemented as a source expression of `Window` it's actually a fragment of the WINDOW expression at the SQL level and thus it should result in a group by its members and not the sum of them. Thanks ElRoberto538 for the report.
2023-11-22Fixed #34985 -- Fixed GeneratedFields.contribute_to_class() crash when apps ↵Mariusz Felisiak
are not populated. Thanks Paolo Melchiorre for the report. Regression in f333e3513e8bdf5ffeb6eeb63021c230082e6f95.
2023-11-18Refs #34975 -- Handled optional source expressions in Expression.get_refs().Simon Charette
While no code is directly exercising get_refs in a way that triggers a crash some expressions such as Window stash None in source_expressions which can obscure the origin of some bugs. Handling None values like we do in other source_expression traversing methods such as .contains_aggregates ensures we don't run into surprises in the future where get_refs() might be used for a different purpose.

2023-11-18Refs #34975 -- Complemented rhs filtering aggregations for __in lookup.Simon Charette
While this isn't a regression it's clear that similar logic should be applied when dealing with lists of expressions passed as a lookup value.
2023-11-18Fixed #34975 -- Fixed crash of conditional aggregate() over aggregations.Simon Charette
Adjustments made to solve_lookup_type to defer the resolving of references for summarized aggregates failed to account for similar requirements for lookup values which can also reference annotations through Aggregate.filter. Regression in b181cae2e3697b2e53b5b67ac67e59f3b05a6f0d. Refs #25307. Thanks Sergey Nesterenko for the report.

This also avoids casting string based expressions in Concat() on PostgreSQL.
2023-11-13Fixed #34967 -- Fixed queryset crash when grouping by constants on SQLite < ↵David Sanders

2023-09-13Modernized enumeration helpers on Python 3.11+.Nick Pope
- use @enum.property https://docs.python.org/3/library/enum.html#enum.property - use @enum.nonmember Using @property on an enum class does not yield the expected result. do_not_call_in_templates attribute works because a @property instance is truthy. We can make this a literal True value as expected by using @enum.nonmember in Python 3.11+. https://docs.python.org/3/library/enum.html#enum.nonmember - used enum.IntEnum/StrEnum Python 3.11+ has ReprEnum which uses int.__str__() and str.__str__() for __str__() in the `IntEnum` and `StrEnum` subclasses. We can emulate that for Python < 3.11. https://docs.python.org/3/library/enum.html#enum.ReprEnum https://docs.python.org/3/library/enum.html#enum.IntEnum https://docs.python.org/3/library/enum.html#enum.StrEnum
2023-09-13Refs #34233 -- Used @staticmethod with TextChoices._generate_next_value_().Nick Pope
Now that Python 3.10 is the minimum supported version, we can decorate _generate_next_value_() with @staticmethod. It wasn't possible before as Python < 3.10 does not support calling static methods direct from the class body. https://docs.python.org/3/library/enum.html#enum.Enum._generate_next_value_
2023-09-12Renamed ChoicesMeta to ChoicesType.Nick Pope
This also uses enum.EnumType for Python 3.11+ as Python 3.11 renamed EnumMeta to EnumType. While the former is still available as an alias of the latter for now, let's prefer the canonical name for this. Check out https://docs.python.org/3/library/enum.html#enum.EnumType
