This should make it more straightforward to move forward when deprecation ends.
2022-07-12Fixed #27236 -- Deprecated Meta.index_together in favor of Meta.indexes.David Wobrock
This also deprecates AlterIndexTogether migration operation.

2022-02-07Refs #33476 -- Reformatted code with Black.django-bot

Regression in 3aa545281e0c0f9fac93753e3769df9e0334dbaa. Thanks Hervé Le Roy for the report.
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.
2021-10-28Removed unused model's Options.installed.Mariusz Felisiak
Unused since f9698c43918c118a29516cbef4e23c197eb2dc25.
2020-12-15Fixed #31007 -- Allowed specifying type of auto-created primary keys.Tom Forbes

2020-04-07Refs #27666 -- Ensured relationship consistency on delayed reloads.Simon Charette
Delayed reloads of state models broke identity based relationships between direct and non-direct ancestors. Basing models.Options related objects map of model labels instead of their identity ensured relationship consistency is maintained. Refs #30966. Co-authored-by: Hasan Ramezani <hasan.r67@gmail.com>
2020-02-19Refs #31187 -- Added total_unique_constraints property to model's Options.Mariusz Felisiak

2020-01-29Used model's Options.label/label_lower where applicable.Mariusz Felisiak
2020-01-16Fixed #29998 -- Allowed multiple OneToOneFields to the parent model.Mariusz Felisiak
We assumed that any OneToOneField's in a child model must be the parent link and raised an error when parent_link=True was not specified. This patch allows to specify multiple OneToOneField's to the parent model. OneToOneField's without a custom related_name will raise fields.E304 and fields.E305 so this should warn users when they try to override the auto-created OneToOneField.
2020-01-07Simplified model's Options.add_field() a bit.Taoup
2019-09-09Refs #29444 -- Allowed returning multiple fields from INSERT statements on ↵Johannes Hoppe

This reverts commit 550cb3a365dee4edfdd1563224d5304de2a57fda because try/except performs better.
2017-08-31Simplified model's Options._get_fields() a bit.Sergey Fedoseev
2017-08-23Removed unneeded iter() calls.Sergey Fedoseev
A few of these were unnecessarily added in 2b281cc35ed9d997614ca3c416928d7fabfef1ad.
