2024-07-17[5.0.x] Fixed #35594 -- Added unique nulls distinct validation for expressions.Simon Charette
Thanks Mark Gensler for the report. Backport of adc0b6aac3f8a5c96e1ca282bc9f46e28d20281c from main.
2024-07-17[5.0.x] Refs #30581 -- Made unattached UniqueConstraint(fields) validation ↵Simon Charette
testable. The logic allowing UniqueConstraint(fields).validate to preserve backward compatiblity with Model.unique_error_message failed to account for cases where the constraint might not be attached to a model which is a common pattern during testing. This changes allows for arbitrary UniqueConstraint(fields) to be tested in isolation without requiring actual models backing them up. Co-authored-by: Mark G <mark.gensler@protonmail.com> Backport of 13922580cccfb9ab2922ff4943dd39da56dfbd8c from main.
2023-10-12[5.0.x] Refs #34840 -- Fixed ↵Mariusz Felisiak
test_validate_nullable_textfield_with_isnull_true() on databases that don's support table check constraints. Thanks Tim Graham for the report. Backport of 9fd3a0ffc8fb8e532b0d5717f99fb15aff175a6c from main
2023-09-22[5.0.x] Fixed #34840 -- Avoided casting string base fields on PostgreSQL.Mariusz Felisiak
Thanks Alex Vandiver for the report. Regression in 09ffc5c1212d4ced58b708cbbf3dfbfb77b782ca. Backport of 779cd28acb1f7eb06f629c0ea4ded99b5ebb670a from main.
2023-08-11Fixed #34743 -- Fixed Meta.constraints validation crash when using pk.Francesco Panico
Thanks Nwawel A Iroume for the report.
2023-08-04Fixed #34754 -- Fixed JSONField check constraints validation on NULL values.Simon Charette
The __isnull lookup of JSONField must special case Value(None, JSONField()) left-hand-side in order to be coherent with its convoluted null handling. Since psycopg>=3 offers no way to pass a NULL::jsonb the issue is resolved by optimizing IsNull(Value(None), True | False) to True | False. Regression in 5c23d9f0c32f166c81ecb6f3f01d5077a6084318. Thanks Alexandre Collet for the report.

Thanks Simon Charette, Keryn Knight, and Mariusz Felisiak for reviews.
2022-05-05Refs #30581 -- Moved CheckConstraint tests for conditional expressions to ↵Mariusz Felisiak

2020-04-17Refs #31351 -- Made partial constraints tests use required_db_features.Mariusz Felisiak
This will notably silence the warnings issued when running the test suite on MySQL and MariaDB.

2019-10-01Fixed #30651 -- Made __eq__() methods return NotImplemented for not ↵ElizabethU
implemented comparisons. Changed __eq__ to return NotImplemented instead of False if compared to an object of the same type, as is recommended by the Python data model reference. Now these models can be compared to ANY (or other objects with __eq__ overwritten) without returning False automatically.

2018-10-02Refs #11964 -- Changed CheckConstraint() signature to use keyword-only ↵Simon Charette
