[6.0.x] Fixed #36847 -- Ensured auto_now_add fields are set on pre_save().

2026-01-29T13:38:53Z

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. Backport of fe189dc43ab3eddbbceefb6834893b73ca60d5ed from main.

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.

Accessing generated field values on unsaved models caused a crash when validating CheckConstraints and UniqueConstraints with expressions.
