2022-04-06Fixed #33471 -- Made AlterField operation a noop when changing "choices".sarahboyce
This also allows customizing attributes of fields that don't affect a column definition.
2022-03-24Refs #32365 -- Removed internal uses of utils.timezone.utc alias.Carlton Gibson
Remaining test case ensures that uses of the alias are mapped canonically by the migration writer.
2022-02-16Made Field.error_messages a cached property.Collin Anderson
This speeds up field creation and reduces memory usage.
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
2022-02-03Refs #33476 -- Refactored problematic code before reformatting by Black.Mariusz Felisiak
In these cases Black produces unexpected results, e.g. def make_random_password( self, length=10, allowed_chars='abcdefghjkmnpqrstuvwxyz' 'ABCDEFGHJKLMNPQRSTUVWXYZ' '23456789', ): or cursor.execute(""" SELECT ... """, [table name], )
2022-01-14Fixed #33441 -- Restored immutability of models.Field.__hash__().Adam Johnson
Regression in 502e75f9ed5476ffe8229109acf0c23999d4b533.
2022-01-04Fixed #33406 -- Avoided creation of MaxLengthValidator(None) when resolving ↵Keryn Knight
Value.output_field for strings. This brings the behaviour in line with Field subclasses which append to the validators within __init__(), like BinaryField, and prevents the creation of a validator which incorrectly throws a TypeError, if it were used.
2021-12-21Fixed #33374 -- Fixed ExpressionWrapper annotations with full queryset.David Wobrock
2021-09-28Fixed #33033 -- Prevented models.DecimalField from accepting NaN values.Chinmoy Chakraborty
2021-09-23Fixed #33133 -- Fixed handling NullBooleanField in historical migrations.Mariusz Felisiak
Regression in d992f4e3c29a81c956d3d616f0bc19701431b26e.

2021-07-30Refs #32966 -- Simplified the _check_fix_default_value() implementations.Chris Jerdonek
2021-07-30Refs #32966 -- Added _to_naive() and _get_naive_now() for use in ↵Chris Jerdonek
DateTimeCheckMixin classes.
2021-07-30Fixed #32966 -- Fixed TimeField.check() crash for timezone-aware times in ↵Chris Jerdonek
default when USE_TZ = True.
2021-07-15Refs #32508 -- Raised Type/ValueError instead of using "assert" in ↵Daniyal
django.db.models. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2021-07-07Fixed #32840 -- Optimized Field.get_col().Keryn Knight
get_col() used "self" as "output_field" when it was not given, and unnecessarily compared "self" to "self". Co-authored-by: Chris Jerdonek <chris.jerdonek@gmail.com> Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2021-06-15Fixed #30427, Fixed #16176 -- Corrected setting descriptor in ↵Carlton Gibson

Follow up to b7a3a6c9ef0a89625881b47594120bca55fa2e49.
2020-11-02Fixed #32132 -- Fixed column types in m2m intermediary tables for ↵David-Wobrock

Thanks Simon Charette and Mariusz Felisiak for reviews.
2020-09-09Fixed #31750 -- Made models.Field equality compare models for inherited fields.Ryan Hiebert
2020-06-05Fixed #31663 -- Made DecimalField.to_python() handle non-numeric invalid values.Sasha Pachev
2020-05-08Fixed #12990, Refs #27694 -- Added JSONField model field.sage
Thanks to Adam Johnson, Carlton Gibson, Mariusz Felisiak, and Raphael Michel for mentoring this Google Summer of Code 2019 project and everyone else who helped with the patch.

2020-04-27Removed unnecessary tuple wrapping of single format string argument.François Freitag
2020-04-24Refs #31369 -- Deprecated models.NullBooleanField in favor of ↵Tim Schilling
BooleanField(null=True).
2020-02-24Fixed #31286 -- Made database specific fields checks databases aware.Taoup
Follow up to 0b83c8cc4db95812f1e15ca19d78614e94cf38dd.
2020-01-15Fixed #31124 -- Fixed setting of get_FOO_display() when overriding inherited ↵Carlton Gibson
choices. Regression in 2d38eb0ab9f78d68c083a5b78b1eca39027b279a
2020-01-11Fixed #31155 -- Fixed a system check for the longest choice when a named ↵Mariusz Felisiak
group contains only non-string values. Regression in b6251956b69512bf230322bd7a49b629ca8455c6. Thanks Murat Guchetl for the report.
2019-11-19Fixed #30987 -- Added models.PositiveBigIntegerField.Caio Ariede
2019-11-05Refs #30095 -- Added Field._choices_is_value().Hasan Ramezani
This allows fields classes to override the validation of choices' values.
2019-11-04Fixed #30931 -- Restored ability to override Model.get_FIELD_display().Carlton Gibson
Thanks Sergey Fedoseev for the implementation idea. Regression in a68ea231012434b522ce45c513d84add516afa60.
2019-10-31Refs #30095 -- Simplified Field._check_choices() a bit.Mariusz Felisiak
Using an internal is_value() hook to check whether Field.choices is iterable is misleading.
2019-09-24Removed some outdated backwards compatibility imports and misleading comments.Mads Jensen
EmptyResultSet moved in 46509cf13dbf049f75077981c29ef2c60b5a96ab. FieldDoesNotExist moved in 8958170755b37ce346ae5257c1000bd936faa3b0.

2019-09-09Refs #29444 -- Allowed returning multiple fields from INSERT statements on ↵Johannes Hoppe
PostgreSQL. Thanks Florian Apolloner, Tim Graham, Simon Charette, Nick Pope, and Mariusz Felisiak for reviews.
2019-09-09Fixed #30757 -- Added a system check to ensure max_length fits the longest ↵Nick Pope
choice.
2019-09-02Refs #28442 -- Adjusted related lookups handling of expression rhs.Simon Charette
Expressions should never be prepared as other Lookup.get_prep_lookup implementations hint at by returning early on the presence of the resolve_expression attribute. The previous solution was only handling lookups against related fields pointing at AutoFields and would break for foreign keys to other fields. It was also causing bidirectional coupling between model fields and expressions which the method level import of OuterRef was a symptom of.
2019-08-20Fixed #29979, Refs #17337 -- Extracted AutoField field logic into a mixin ↵Nick Pope
and refactored AutoFields. This reduces duplication by allowing AutoField, BigAutoField and SmallAutoField to inherit from IntegerField, BigIntegerField and SmallIntegerField respectively. Doing so also allows for enabling the max_length warning check and minimum/maximum value validation for auto fields, as well as providing a mixin that can be used for other possible future auto field types such as a theoretical UUIDAutoField.
2019-08-15Fixed #30449 -- Fixed RelatedFieldListFilter/RelatedOnlyFieldListFilter to ↵zeyneloz
respect model's Meta.ordering. Regression in 6d4e5feb79f7eabe8a0c7c4b87f25b1a7f87ca0b. Co-Authored-By: Mariusz Felisiak <felisiak.mariusz@gmail.com>

2019-08-02Fixed #30661 -- Added models.SmallAutoField.Nick Pope
2019-07-25Fixed #30657 -- Allowed customizing Field's descriptors with a ↵Jon Dufresne
descriptor_class attribute. Allows model fields to override the descriptor class used on the model instance attribute.
2019-07-25Refs #30657 -- Made DeferredAttribute.__init__() to take a field instance ↵Jon Dufresne
instead of a field name.
2019-06-28Fixed #30400 -- Improved typography of user facing strings.Jon Dufresne
Thanks Claude Paroz for assistance with translations.
2019-05-02Fixed #29529 -- Allowed models.fields.FilePathField to accept a callable path.Mykola Kokalko
