fields. With thanks to Konrad Świat, Loïc Bistuer, Russell Keith-Magee, and Mariusz Felisiak. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2025-03-28Fixed #36239 -- Fixed a crash in ManyToManyField.through_fields check when ↵saJaeHyukc
to model is invalid. Signed-off-by: saJaeHyukc <wogur981208@gmail.com>

2024-08-28Refs #16055 -- Adjusted deprecation warning stacklevel in ↵Simon Charette

2024-07-09Fixed #35580 -- Allowed related fields referencing auto-created through models.jason_bruce
2024-07-04Fixed #35569 -- Improved wording of invalid ForeignKey error message.Jacob Walls
2024-05-21Fixed #35405 -- Converted get_cache_name into a cached property in ↵Adam Johnson
FieldCacheMixin. FieldCacheMixin is used by related fields to track their cached values. This work migrates get_cache_name() to be a cached property to optimize performance by reducing unnecessary function calls when working with related fields, given that its value remains constant.

2023-03-14Refs #28329 -- Fixed Cast() with ForeignKey to integer fields on MySQL.David Wobrock
2023-02-01Refs #33476 -- Applied Black's 2023 stable style.David Smith
Black 23.1.0 is released which, as the first release of the year, introduces the 2023 stable style. This incorporates most of last year's preview style. https://github.com/psf/black/releases/tag/23.1.0
2023-01-18Refs #34233 -- Used @functools.cache.Nick Pope
Python 3.9+ supports @functools.cache as an alias for @functools.lru_cache(maxsize=None).
2022-12-28Fixed #18468 -- Added support for comments on columns and tables.kimsoungryoul
Thanks Jared Chung, Tom Carrick, David Smith, Nick Pope, and Mariusz Felisiak for reviews. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com> Co-authored-by: Nick Pope <nick@nickpope.me.uk>
2022-11-18Removed unnecessary ForeignKey.get_reverse_path_info().Mariusz Felisiak
get_reverse_path_info() is already inherited from ForeignObject.
2022-10-31Used more augmented assignment statements.Nick Pope
Identified using the following command: $ git grep -I '\(\<[_a-zA-Z0-9]\+\>\) *= *\1 *[-+/*^%&|<>@]'
2022-09-02Fixed #29799 -- Allowed registering lookups per field instances.Allen Jonathan David
Thanks Simon Charette and Mariusz Felisiak for reviews and mentoring this Google Summer of Code 2022 project.
2022-07-27Refs #32948, Refs #32946 -- Used Q.create() internally for dynamic Q() objects.Nick Pope
Node.create() which has a compatible signature with Node.__init__() takes in a single `children` argument rather than relying in unpacking *args in Q.__init__() which calls Node.__init__(). In addition, we were often needing to unpack iterables into *args and can instead pass a list direct to Node.create().
2022-05-02Fixed #33413 -- Made migrations propage collations to related fields.David Wobrock
2022-04-22Refs #31223 -- Added __class_getitem__() to ForeignKey.Collin Anderson
2022-02-16Fixed #33515 -- Prevented recreation of migration for ManyToManyField to ↵Mariusz Felisiak
lowercased swappable setting. Thanks Chris Lee for the report. Regression in 43289707809c814a70f0db38ca4f82f35f43dbfd. Refs #23916.
2022-02-07Refs #33476 -- Refactored code to strictly match 88 characters line length.Mariusz Felisiak
2022-02-07Refs #33476 -- Reformatted code with Black.django-bot
2021-12-10Corrected return value of ForeignKey.db_check().Adam Johnson
Field.db_check() should return None or a SQL string. Returning [] happened to work because it’s falsey.
2021-11-03Fixed #32996 -- Cached PathInfos on relations.Keryn Knight
PathInfo values are ostensibly static over the lifetime of the object for which they're requested, so the data can be memoized, quickly amortising the cost over the process' duration.
2021-10-06Fixed #33131 -- Improved error messages for clashing reverse accessor names.Bernd Wechner
2021-09-09Fixed #33084 -- Removed incorrect system check for ManyToManyField with ↵Hasan Ramezani
limit_choices_to.
2021-08-06Fixed #32983 -- Added system check for redundant related_name on symmetrical ↵Nick Touran
M2M fields. Since ManyToManyFields defined with `symmetrical=True` do not add a related field to the target model, including a `related_name` argument will never do what the coder likely expects. This makes including a related_name with a symmetrical model raise a system check warning. ticket-32983
2021-07-28Refs #32946 -- Changed internal usage of dynamic Q() objects construction to ↵Keryn Knight
use non-kwargs initialization. This prefers non-kwargs construction of dynamically generated Q() objects to create a single Q() object instead of many and then combining them, where possible.
2021-07-22Fixed #32951 -- Removed Query.where_class & co.Nick Pope
Unused since 3caf957ed5eaa831a485abcb89f27266dbf3e82b.

when not passed during initialization. Thanks Simon Charette for the implementation idea.

between apps.
2020-12-29Added app labels to related fields checks messages E302-E305.Mariusz Felisiak
2020-12-29Used model's Options.label where applicable.Mariusz Felisiak
Follow up to b7a3a6c9ef0a89625881b47594120bca55fa2e49.
2020-06-26Fixed #31742 -- Fixed makemigrations crash on ForeignKey to an app with ↵Mariusz Felisiak
mixed case label. Regression in 9e1b6b8a66af4c2197e5b1b41eb9dbb36e4f6502. Thanks Ignacio Santolin for the report.
