Fixed #36906 -- Handled coalescing JSON-primitive strings and JSON values on Oracle.

2026-03-16T15:53:25Z

Fixed #36847 -- Ensured auto_now_add fields are set on pre_save().

2026-01-29T13:11:33Z

Regression in 94680437a45a71c70ca8bd2e68b72aa1e2eff337. Refs #27222. During INSERT operations, `field.pre_save()` is called to prepare values for db insertion. The `add` param must be `True` for `auto_now_add` fields to be populated. The regression commit passed `False`, causing `auto_now_add` fields to remain `None` when used by other fields, such as `upload_to` callables. Thanks Ran Benita for the report.

Fixed #36233 -- Avoided quantizing integers stored in DecimalField on SQLite.

Refs #36806 -- Removed unnecessary null=True from GeneratedField in test models.

2025-12-23T01:38:55Z

Test coverage is preserved because the tests only verify that generated fields can produce NULL values when the source field is nullable. This addresses system check warnings in the test suite after 6025eab3c509b4de922117e16866bbfe0ee99aa6.

Fixed #36765 -- Added support for stored GeneratedFields on Oracle 23ai/26ai (23.7+).

2025-12-13T15:38:04Z

Thanks Jacob Walls for the review.

Fixed #35381 -- Added JSONNull() expression.

2025-10-29T19:00:52Z

Thanks Jacob Walls for the review.

Refs #35167 -- Fixed test_bulk_update_custom_get_prep_value() crash on databases that don't support primitives in JSONFields.

2025-02-20T07:14:18Z

For example on Oracle < 21c.

Fixed #35167 -- Delegated to super() in JSONField.get_db_prep_save().

2025-02-18T16:28:24Z

Avoids reports of bulk_update() sending Cast expressions to JSONField.get_prep_value(). Co-authored-by: Simon Charette

Fixed #36086 -- Fixed crash when using GeneratedField with non-AutoField pk.

2025-01-13T10:13:29Z

The previous logic was systematically attempting to retrieve last_insert_id even for models without an AutoField primary key when they had a GeneratedField on backends that can't return columns from INSERT. The issue affected MySQL, SQLite < 3.35, and Oracle when the use_returning_into option was disabled and could result in either crashes when the non-auto primary key wasn't an IntegerField subclass or silent misassignment of bogus insert ids (0 or the previous auto primary key insert value) to the first defined generated field value.

Fixed #35695 -- Ensured FileFields use a storage pointing to a temp directory in model_fields tests.
