chango.git/tests/model_fields/test_generatedfield.py, branch devmain

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

Thanks Jacob Walls for the review.

Refs #27222 -- Refreshed GeneratedFields values on save() initiated update.

2025-09-13T22:27:49Z

This required implementing UPDATE RETURNING machinery that heavily borrows from the INSERT one.

Fixed #33312 -- Raised explicit exception when copying deferred model instances.

2025-05-16T06:13:57Z

Previously save() would crash with an attempted forced update message, and both save(force_insert=True) and bulk_create() would crash with DoesNotExist errors trying to retrieve rows with an empty primary key (id IS NULL). Implementing deferred field model instance copying might be doable in certain cases (e.g. when all the deferred fields are db generated) but that's not trivial to implement in a backward compatible way. Thanks Adam Sołtysik for the report and test and Clifford for the review.

Fixed #36262 -- Made GeneratedField.db_persist a required key-word argument.

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 #35560 -- Made Model.full_clean() ignore GeneratedFields for constraints.

2024-07-04T09:45:15Z

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

Fixed #35350 -- Fixed save() with pk set on models with GeneratedFields.

2024-04-10T13:43:50Z

Thanks Matt Hegarty for the report and Simon Charette and Natalia Bidart for the reviews. Regression in f333e35.

Fixed #35344, Refs #34838 -- Corrected output_field of resolved columns for GeneratedFields in aliased tables.

2024-04-01T17:54:38Z

Thanks Simon Charette for the review.

Fixed #35127 -- Made Model.full_clean() ignore GeneratedFields.

2024-01-19T07:55:50Z

Thanks Claude Paroz for the report. Regression in f333e3513e8bdf5ffeb6eeb63021c230082e6f95.

Fixed #35019 -- Fixed save() on models with both GeneratedFields and ForeignKeys.

2023-12-08T08:46:11Z

Thanks Deb Kumar Das for the report. Regression in f333e3513e8bdf5ffeb6eeb63021c230082e6f95.
