2025-11-06Fixed #36702 -- Made bulk_create() return pk values set by an expression.us77ipis
2025-10-24Fixed IntegrityError in bulk_create.tests.BulkCreateTransactionTests due to ↵Natalia
duplicate primary keys. Some tests in BulkCreateTransactionTests were inserting Country objects with hardcoded primary keys, which could conflict with existing rows (if the sequence value wasn't bumped by another test). Updated the tests to dynamically select an unused primary key instead. Thanks to Simon Charette for the exhaustive and enlightening review.
2025-08-21Fixed failing bulk_create test raising IntegrityError when run in reverse.Natalia
When running the `bulk_create` tests with Postgres settings and `--reverse`, the following IntegrityError was raised in bulk_create.tests.BulkCreateTransactionTests.test_objs_with_and_without_pk: django.db.utils.IntegrityError: duplicate key value violates unique constraint "bulk_create_country_pkey" DETAIL: Key (id)=(1) already exists. This branch fixes this by ensuring the ID is unique since DB sequences are not resetted between tests.
2025-08-15Avoided usage of DEBUG setting override in bulk_create tests.Simon Charette
Asserting an upper bound for the number of executed queries can be achieved by using CaptureQueriesContext instead of enabling the whole DEBUG machinery.
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.

2025-03-26Fixed #36260 -- Made bulk_create() work with DB-generated primary keys.Dmitry Shachnev

2025-02-01Fixed #36088 -- Avoided unnecessary DEFAULT usage on bulk_create().Simon Charette
When all values of a field with a db_default are DatabaseDefault, which is the case most of the time, there is no point in specifying explicit DEFAULT for all INSERT VALUES as that's what the database will do anyway if not specified. In the case of PostgreSQL doing so can even be harmful as it prevents the usage of the UNNEST strategy and in the case of Oracle, which doesn't support the usage of the DEFAULT keyword, it unnecessarily requires providing literal db defaults. Thanks Lily Foote for the review.
