2025-09-16Fixed #36426 -- Added support for further iterables in ↵blingblin-g
prefetch_related_objects(). Thanks Sarah Boyce for the review.
2025-09-16Refs #27222 -- Deduplicated db_returning fields in Model.save().Jacob Walls
Follow-up to 94680437a45a71c70ca8bd2e68b72aa1e2eff337.
2025-09-16Fixed #36580 -- Fixed constraint validation crash when condition uses a ↵SaJH
ForeignObject. Follow-up to e44e8327d3d88d86895735c0e427102063ff5b55. Refs #36222.
2025-09-14Fixed #27222 -- Refreshed model field values assigned expressions on save().Simon Charette
Removed the can_return_columns_from_insert skip gates on existing field_defaults tests to confirm the expected number of queries are performed and that returning field overrides are respected.
2025-09-14Refs #27222 -- Refreshed GeneratedFields values on save() initiated update.Simon Charette
This required implementing UPDATE RETURNING machinery that heavily borrows from the INSERT one.
2025-09-05Fixed #36564 -- Changed DEFAULT_AUTO_FIELD from AutoField to BigAutoField.Tim Graham
2025-09-04Fixed #36481 -- Fixed QuerySet.update concrete fields check.Ryan P Kilby
FieldError is now emitted for invalid update calls involving reverse relations, where previously they failed with AttributeError.
2025-09-03Fixed CVE-2025-57833 -- Protected FilteredRelation against SQL injection in ↵Jake Howard
column aliases. Thanks Eyal Gabay (EyalSec) for the report.
2025-08-29Fixed #36431 -- Returned tuples for multi-column ForeignObject in ↵SaJH
values()/values_list(). Thanks Jacob Walls and Simon Charette for tests. Signed-off-by: SaJH <wogur981208@gmail.com>
2025-08-29Refs #36152 -- Suppressed duplicate warning when using "%" in alias via ↵Jacob Walls
values().
2025-08-28Refs #27222 -- Adapted RETURNING handling to be usable for UPDATE queries.Simon Charette
Renamed existing methods and abstractions used for INSERT … RETURNING to be generic enough to be used in the context of UPDATEs as well. This also consolidates SQL compliant implementations on BaseDatabaseOperations.
2025-08-28Refs #27222 -- Implemented ↵Simon Charette
BaseDatabaseOperations.return_insert_columns()/fetch_returned_insert_rows().
2025-08-23Refs #470 -- Adjusted Field.db_returning to be backend agnostic.Simon Charette
Determining if a field is db_returning based on the default connection feature availability prevents the usage of RETURNING for db_default fields in setups where non-default backends do support RETURNING. Whether or not the field should be attempted to be returned is already checked at the compiler level which is backend aware.
2025-08-21Refs #36430, #36416, #34378 -- Simplified batch size calculation in ↵Jacob Walls
QuerySet.in_bulk().
2025-08-21Fixed #36430 -- Removed artificially low limit on single field bulk ↵Jacob Walls
operations on SQLite.
2025-08-15Refs #36490 -- Simplified QuerySet._batched_insert returning fields handling.Simon Charette
Whether or not returning_fields should be specified to _insert is not a function of each batches so the conditional can be moved outside of the loop.
2025-08-15Fixed #36490 -- Avoided unnecessary transaction in bulk_create.Simon Charette
When dealing with an heterogeneous set of object with regards to primary key assignment that fits in a single batch there's no need to wrap the single INSERT statement in a transaction.
2025-08-12Remove unused OneToOneField from DatabaseWrapper.data_types.Tim Graham
OneToOneField uses the type of the related field.
2025-08-11Refs #36210 -- Corrected output_field comparison in ↵Jacob Walls
Subquery.resolve_expression(). Regression in fd569dd45bf0746378faf7f65172497f21ed27f0.
2025-08-07Fixed #36210, Refs #36181 -- Allowed Subquery usage in further lookups ↵Jacob Walls
against composite pks. Follow-up to 8561100425876bde3be4b2a22324655f74ff9609. Co-authored-by: Simon Charette <charette.s@gmail.com>
2025-08-05Fixed #36530 -- Extended fields.E347 to check for ManyToManyField involving ↵jkhall81
CompositePrimaryKey on either side. Thanks to Jacob Walls for the report.
2025-08-04Fixed #35972 -- Fixed lookup crashes after subquery annotations.Jacob Walls
2025-08-04Fixed #34871, #36518 -- Implemented unresolved lookups expression replacement.Simon Charette
This allows the proper resolving of lookups when performing constraint validation involving Q and Case objects. Thanks Andrew Roberts for the report and Sarah for the tests and review.
2025-07-29Fixed #36531 -- Added forkserver support to parallel test runner.Mariusz Felisiak
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.
2025-07-25Refs #36438 -- Made FieldOperation.references_field() detect references in ↵Clifford Gama
GeneratedField.expression. Thanks to Simon Charette for the suggestion and review.
2025-07-25Fixed #36438 -- Made MigrationAutodetector remove generated fields before ↵Clifford Gama
their base fields. Thanks to Colton Saska for the report and to Simon Charette for the review.
2025-07-23Refs #36500 -- Corrected rewrapped long lines fixed via a script.Mike Edmunds
Manually reformatted some comments and docstrings where autofix_w505.py changed the meaning of the formatting.
2025-07-23Refs #36500 -- Rewrapped long docstrings and block comments via a script.django-bot
Rewrapped long docstrings and block comments to 79 characters + newline using script from https://github.com/medmunds/autofix-w505.
2025-07-23Refs #36500 -- Shortened some long docstrings and comments.Mike Edmunds
Manually reformatted some long docstrings and comments that would be damaged by the to-be-applied autofixer script, in cases where editorial judgment seemed necessary for style or wording changes.
2025-07-23Removed double spaces after periods and within phrases.Sarah Boyce
2025-07-22Fixed #36282 -- Used prefetched values in ForwardManyToOneDescriptor from ↵Take Weiland
indirect ancestors. When looking for cached values in ManyRelatedManager and ForwardManyToOneDescriptor walk up the whole chain of ancestors (as long as they are cached) to find the prefetched relation.
2025-07-10Fixed #36502 -- Restored UNNEST strategy for foreign key bulk inserts on ↵Simon Charette
PostgreSQL. Regression in 764af7a3d6c0b543dcf659a2c327f214da768fe4.
2025-07-09Fixed typo in ReverseManyToOneDescriptor docstring.tinmarbusir
2025-07-03Refs #27236 -- Removed references to removed index_together migration methods.Clifford Gama
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.
2025-06-27Fixed #35595, #35962 -- Removed indexes and constraints before fields in ↵wookkl
migrations.
2025-06-23Fixed #35305 -- Avoided recreating constraints on fields renamed via db_column.Jacob Walls
2025-06-20Fixed #36152 -- Deprecated use of "%" in column aliases.Jacob Walls
Unintentional support existed only on SQLite and Oracle.
2025-06-19Refs #35038 -- Reduced CreateModel/AlterConstraint operations when ↵Jacob Walls
optimizing migrations.
2025-06-16Fixed #36380 -- Deferred SQL formatting when running tests with --debug-sql.Natalia
Thanks to Jacob Walls for the report and previous iterations of this fix, to Simon Charette for the logging formatter idea, and to Tim Graham for testing and ensuring that 3rd party backends remain compatible. This partially reverts d8f093908c504ae0dbc39d3f5231f7d7920dde37. Refs #36112, #35448. Co-authored-by: Jacob Walls <jacobtylerwalls@gmail.com>
2025-06-16Fixed #36453 -- Made When.condition resolve with for_save=False.Clifford Gama
Value(None, JSONField()) when used in When.condition incorrectly resolved with for_save=True, resulting in the value being serialized as SQL NULL instead of JSON null. Regression in c1fa3fdd040718356e5a3b9a0fe699d73f47a940. Thanks to Thomas McKay for the report, and to David Sanders and Simon Charettes for the review. Co-authored-by: Sarah Boyce <42296566+sarahboyce@users.noreply.github.com>
2025-06-13Fixed #36433 -- Fixed constraint validation crash when condition uses a ↵Colleen Dunlap
ForeignKey attname. Regression in e44e8327d3d88d86895735c0e427102063ff5b55. Thank you to Jacob Walls for the report. Co-authored-by: Simon Charette <charette.s@gmail.com>
2025-06-12Fixed #36442 -- Cloned FilteredRelation before rename_prefix_from_q.viliam mihalik
2025-06-06Fixed #36419 -- Ensured for_save was propagated when resolving expressions.Clifford Gama
The for_save flag wasn't properly propagated when resolving expressions, which prevented get_db_prep_save() from being called in some cases. This affected fields like JSONField where None would be saved as JSON null instead of SQL NULL. Regression in 00c690efbc0b10f67924687f24a7b30397bf47d9. Thanks to David Sanders and Simon Charette for reviews. Co-authored-by: Adam Johnson <me@adamj.eu>
