2019-11-04[3.0.x] Fixed #30931 -- Restored ability to override Model.get_FIELD_display().Carlton Gibson
Thanks Sergey Fedoseev for the implementation idea. Regression in a68ea231012434b522ce45c513d84add516afa60. Backport of 2d38eb0ab9f78d68c083a5b78b1eca39027b279a from master

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.

2019-02-21Refs #19544 -- Added a fast path for through additions if supported.Simon Charette
The single query insertion path is taken if the backend supports inserts that ignore conflicts and m2m_changed signals don't have to be sent.

2018-11-17Refs #29908 -- Optimized known related objects assignment.Simon Charette
Since CPython implements a C level attrgetter(*attrs) it even outperforms the most common case of a single known related object since the resulting attribute values tuple is built in C.

2018-11-08Fixed #29908 -- Fixed setting of foreign key after related set access if ↵Simon Charette
ForeignKey uses to_field. Adjusted known related objects handling of target fields which relies on from and to_fields and has the side effect of fixing a bug bug causing N+1 queries when using reverse foreign objects. Thanks Carsten Fuchs for the report.
2018-10-24Fixed #29869 -- Made UUIDField.to_python() convert integers.Sanyam Khurana
2018-10-22Fixed #27595 -- Made ForeignKey.get_col() follow target chains.Simon Charette
Previously, foreign relationships were followed only one level deep which prevents foreign keys to foreign keys from being resolved appropriately. This was causing issues such as improper database value conversion for UUIDField on SQLite because the resolved expression's output field's internal type wasn't correct. Added tests to make sure unlikely foreign reference cycles don't cause recursion errors. Refs #24343. Thanks oyooyo for the report and Wayne Merry for the investigation.
2018-10-15Fixed #29725 -- Removed unnecessary join in QuerySet.count() and exists() on ↵oliver
