Refs #28442 -- Adjusted related lookups handling of expression rhs.

2019-09-02T08:52:36Z

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.

Fixed #29979, Refs #17337 -- Extracted AutoField field logic into a mixin and refactored AutoFields.

2019-08-20T07:22:25Z

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.

Fixed #30449 -- Fixed RelatedFieldListFilter/RelatedOnlyFieldListFilter to respect model's Meta.ordering.
