2024-05-22Fixed #35139 -- Prevented file read after ImageField is saved to storage.John Parton
2024-05-21Fixed #35405 -- Converted get_cache_name into a cached property in ↵Adam Johnson
FieldCacheMixin. FieldCacheMixin is used by related fields to track their cached values. This work migrates get_cache_name() to be a cached property to optimize performance by reducing unnecessary function calls when working with related fields, given that its value remains constant.

2024-05-15Fixed #35384 -- Raised FieldError when saving a file without a name to ↵Jonny Park
FileField.
2024-05-14Fixed #35275 -- Fixed Meta.constraints validation crash on UniqueConstraint ↵Mariusz Felisiak
with OpClass(). This also introduces Expression.constraint_validation_compatible that allows specifying that expression should be ignored during a constraint validation.
2024-05-07Fixed #35407 -- Cached model's Options.swapped.Adam Johnson
2024-05-07Fixed #35425 -- Avoided INSERT with force_update and explicit pk.Jacob Walls
Affected models where the primary key field is defined with a default or db_default, such as UUIDField.
2024-05-03Fixed #35422 -- Fixed migrations crash when altering GeneratedField ↵Mariusz Felisiak
referencing rename field. Thanks Sarah Boyce for the report and Simon Charette for the implementation idea.
2024-05-02Fixed #35359 -- Fixed migration operations ordering when adding fields ↵DevilsAutumn
referenced by GeneratedField.expression. Thank you to Simon Charette for the review.
2024-05-02Refs #34007, Refs #35359 -- Added Q.referenced_based_fields property.David Sanders
Thank you to Mariusz Felisiak and Natalia Bidart for the reviews.
2024-04-29Fixed #35412 -- Dropped support for SQLite < 3.31.Mariusz Felisiak
2024-04-25Refs #35339 -- Updated Aggregate class to return consistent source expressions.Chris Muthig
Refactored the filter and order_by expressions in the Aggregate class to return a list of Expression (or None) values, ensuring that the list item is always available and represents the filter expression. For the PostgreSQL OrderableAggMixin, the returned list will always include the filter and the order_by value as the last two elements. Lastly, emtpy Q objects passed directly into aggregate objects using Aggregate.filter in admin facets are filtered out when resolving the expression to avoid errors in get_refs(). Thanks Simon Charette for the review.
2024-04-23Refs #35356 -- Clarified select related with masked field logic.Simon Charette
By always including related objects in the select mask via adjusting the defer logic (_get_defer_select_mask()), it becomes possible for select_related_descend() to treat forward and reverse relationships indistinctively. This work also simplifies and adds comments to select_related_descend() to make it easier to understand.
2024-04-23Fixed #35356 -- Deferred self-referential foreign key fields adequately.Simon Charette
While refs #34612 surfaced issues with reverse one-to-one fields deferrals, it missed that switching to storing remote fields would break self-referential relationships. This change switches to storing related objects in the select mask instead of remote fields to prevent collisions when dealing with self-referential relationships that might have a different directional mask. Despite fixing #21204 introduced a crash under some self-referential deferral conditions, it was simply not working even before that as it aggregated the sets of deferred fields by model. Thanks Joshua van Besouw for the report and Mariusz Felisiak for the review.
2024-04-22Fixed #35392, Refs #34331 -- Allowed importing aprefetch_related_objects ↵James Ostrander
from django.db.models. Thanks James Ostrander for the report and fix, and to Tim Graham and Mariusz Felisiak for the reviews.
2024-04-16Fixed #35373 -- Fixed a crash when indexing a generated field on SQLite.Simon Charette
Generated fields have to be excluded from the INSERT query against the remade table including the index. Thanks Moshe Dicker for the report, David Sanders and Mariusz Felisiak for the review.
2024-04-15Fixed ↵Mariusz Felisiak
backends.oracle.tests.TransactionalTests.test_hidden_no_data_found_exception() on oracledb >= 2.1.2. python-oracledb 2.1.2+ no longer hides 'ORA-1403: no data found' exceptions raised in database triggers: https://github.com/oracle/python-oracledb/issues/321
2024-04-10Fixed #35350 -- Fixed save() with pk set on models with GeneratedFields.Sarah Boyce
Thanks Matt Hegarty for the report and Simon Charette and Natalia Bidart for the reviews. Regression in f333e35.
2024-04-02Fixed #35336 -- Addressed crash when adding a GeneratedField with % literals.Simon Charette
A longer term solution is likely to have a better separation of parametrized DDL altogether to handle checks, constraints, defaults, and generated fields but such a change would require a significant refactor that isn't suitable for a backport. Thanks Adrian Garcia for the report.
2024-04-01Fixed #35344, Refs #34838 -- Corrected output_field of resolved columns for ↵Johannes Westphal
GeneratedFields in aliased tables. Thanks Simon Charette for the review.
