2025-11-04[6.0.x] Fixed #36704 -- Fixed system check error for proxy model with a ↵Hal Blackburn
composite pk. 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. Backport of 74564946c3b42a2ef7d087047e49873847a7e1d9 from main.

2025-08-07Refs #36210 -- Added missing limits in Subquery tests.Jacob Walls
2025-07-28Fixed #36522 -- Added support for filtering composite pks using a tuple of ↵Simon Charette
expressions. Thanks Jacob Walls for the report, and Sarah Boyce and Mariusz Felisiak for reviews.
2025-06-30Fixed #36464 -- Fixed "__in" tuple lookup on backends lacking native support.Simon Charette
When native support for tuple lookups is missing in a DB backend, it can be emulated with an EXISTS clause. This is controlled by the backend feature flag "supports_tuple_lookups". The mishandling of subquery right-hand side in `TupleIn` (added to support `CompositePrimaryKey` in Refs #373) was likely missed because the only core backend we test with the feature flag disabled (Oracle < 23.4) supports it natively. Thanks to Nandana Raol for the report, and to Sarah Boyce, Jacob Walls, and Natalia Bidart for reviews.

2025-04-11Fixed #36288 -- Addressed improper handling of duplicates in values_list().Simon Charette
Now that selected aliases are stored in sql.Query.selected: dict[str, Any] the values_list() method must ensures that duplicate field name references are assigned unique aliases. Refs #28900. Regression in 65ad4ade74dc9208b9d686a451cd6045df0c9c3a. Thanks Claude for the report.
2025-04-03Fixed #36290 -- Made TupleIn() lookup discard tuples containing None.Simon Charette
Just like the In() lookup discards of None members TupleIn() should discard tuples containing any None as NULL != NULL in SQL and the framework expects such queries to be elided under some circumstances. Refs #31667, #36116. Thanks Basptise Mispelon for bisecting the regression to 626d77e.
2025-02-13Fixed #36181 -- Allowed Subquery usage in __in lookups against composite pks.Simon Charette
Thanks Jacob Walls for the report.
2025-02-11Fixed #36149 -- Allowed subquery values against tuple exact and in lookups.Simon Charette
Non-tuple exact and in lookups have specialized logic for subqueries that can be adapted to properly assign select mask if unspecified and ensure the number of involved members are matching on both side of the operator.
