2025-12-17Fixed #27380 -- Added "raw" argument to m2m_changed signals.Mariusz Felisiak
2025-12-17Refs #27380 -- Added ManyRelatedManager.set_base() hook.Mariusz Felisiak
2025-12-17Refs #27380 -- Made ManyRelatedManager.set() use *_base() hooks.Mariusz Felisiak
2025-12-17Refs #27380 -- Made ManyRelatedManager.add()/clear()/remove() implementation ↵Mariusz Felisiak
more consistent. This also adds _add_base(), _clear_base(), and _remove_base() internal hooks.
2025-12-16Fixed #36594 -- Improved UniqueConstraint's nulls_distinct system check message.Mridul Dhall
Clarified that the nulls_distinct argument is not supported, as opposed to certain values for the argument. Thanks Russell Owen for the report.

2025-12-10Refs #36025 -- Made get_prep_lookup() pass output_field when wrapping direct ↵Clifford Gama
values in Value. Previously, only strings were supplied with an output_field when wrapping direct value iterable elements in Value expressions for ExpressionList. This caused problems for __in lookups on JSONField when using expressions alongside direct values, as JSONField values can have different types which need to be adapted by the field's get_db_prep_value(). Refs #36689. Thanks Jacob Walls for the review.
2025-12-10Refs #36689 -- Serialized JSONIn rhs parameters wrapped in Value expressions.Clifford Gama
2025-12-10Fixed #36689 -- Fixed top-level JSONField __in lookup failures on MySQL and ↵Clifford Gama
Oracle. Added a JSONIn lookup to handle correct serialization and extraction for JSONField top-level __in queries on backends without native JSON support. KeyTransformIn now subclasses JSONIn. Co-authored-by: Jacob Walls <jacobtylerwalls@gmail.com> Thanks Jacob Walls for the report and review.
2025-12-05Fixed #36722 -- Moved AutoFieldMixin validate_autopk_value() check to ↵Clifford Gama
get_db_prep_save. The validation in validate_autopk_value is specific to saving. Having it in get_db_prep_value caused Value(0, AutoField()) to fail unexpectedly when used in a filter on MySQL. Thanks Jacob Walls for the review.

This is also applicable on CockroachDB.
2025-11-24Fixed #36751 -- Fixed empty filtered aggregation crash over annotated queryset.Simon Charette
Regression in b8e5a8a9a2a767f584cbe89a878a42363706f939. Refs #36404. The replace_expressions method was innapropriately dealing with falsey but not None source expressions causing them to also be potentially evaluated when __bool__ was invoked (e.g. QuerySet.__bool__ evaluates the queryset). The changes introduced in b8e5a8a9a2, which were to deal with a similar issue, surfaced the problem as aggregation over an annotated queryset requires an inlining (or pushdown) of aggregate references which is achieved through replace_expressions. In cases where an empty Q object was provided as an aggregate filter, such as when the admin facetting feature was used as reported, it would wrongly be turned into None, instead of an empty WhereNode, causing a crash at aggregate filter compilation. Note that the crash signature differed depending on whether or not the backend natively supports aggregate filtering (supports_aggregate_filter_clause) as the fallback, which makes use Case / When expressions, would result in a TypeError instead of a NoneType AttributeError. Thanks Rafael Urben for the report, Antoliny and Youngkwang Yang for the triage.

2025-11-04Fixed #36704 -- Fixed system check error for proxy model with a composite pk.Hal Blackburn
Proxy models subclassing a model with a CompositePrimaryKey were incorrectly reporting check errors because the check that requires only local fields to be used in a composite pk was evaluated against the proxy subclass, which has no fields. To fix this, composite pk field checks are not evaluated against proxy subclasses, as none of the checks are applicable to proxy subclasses. This also has the benefit of not double-reporting real check errors from an invalid superclass pk. Thanks Clifford Gama for the review.
2025-10-29Refs #35381 -- Deprecated using None in JSONExact rhs to mean JSON null.Clifford Gama

missing from explicit grouping." This reverts commit ea3a71c2d09f8281d8a50ed20e40e1fb13db5cd9. The implementation was flawed, as self.group_by contains Cols, not aliases.

This change ensures that we don’t create new instances of fetch modes when pickling and unpickling, saving memory and preserving their singleton nature.

2025-09-22Fixed #36612 -- Fixed a KeyTextTransform crash on MySQL against annotations.Simon Charette
MySQL only supports the ->> when used directly against columns, this can be inferred by the presence of lhs.output_field.model as model bounds fields are directly tied to columns. Purposely don't systematically switch to using JSON_QUOTE(JSON_EXTRACT(...)) as there might be functional indices out there that rely on the SQL remaining stable between versions. Thanks Jacob Tavener for the report.
