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.

2018-11-13Refs #29641 -- Refactored database schema constraint creation.Simon Charette

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.

foreign keys that use to_field. Regression in ee49306176a2d2f1751cb890bd607d42c7c09196.
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.
