2025-03-10Fixed #36066 -- Documented that Q objects can be used directly in annotations.samruddhiDharankar
2025-03-03Fixed #35444 -- Added generic support for Aggregate.order_by.Chris Muthig
This moves the behaviors of `order_by` used in Postgres aggregates into the `Aggregate` class. This allows for creating aggregate functions that support this behavior across all database engines. This is shown by moving the `StringAgg` class into the shared `aggregates` module and adding support for all databases. The Postgres `StringAgg` class is now a thin wrapper on the new shared `StringAgg` class. Thank you Simon Charette for the review.

2024-08-28Removed outdated note about lack of subquery support in MySQL.Adam Johnson
2024-07-03Refs #28900 -- Made SELECT respect the order specified by values(*selected).Simon Charette
Previously the order was always extra_fields + model_fields + annotations with respective local ordering inferred from the insertion order of *selected. This commits introduces a new `Query.selected` propery that keeps tracks of the global select order as specified by on values assignment. This is crucial feature to allow the combination of queries mixing annotations and table references. It also allows the removal of the re-ordering shenanigans perform by ValuesListIterable in order to re-map the tuples returned from the database backend to the order specified by values_list() as they'll be in the right order at query compilation time. Refs #28553 as the initially reported issue that was only partially fixed for annotations by d6b6e5d0fd4e6b6d0183b4cf6e4bd4f9afc7bf67. Thanks Mariusz Felisiak and Sarah Boyce for review.
