#27970 closed New feature (fixed)

Allow in_bulk() to use other unique fields besides the primary key

Description

Currently in_bulk() has a very limited set of use-cases, especially since a lot of Django users prefer to keep the ID as the PK even when another field could be used. It could be expanded to be more useful if it could be used on fields other than the ID.

For backwards compatibility, it should only work on unique fields.

Proposed syntax: Foo.objects.in_bulk(['1', '2', 'AB123'], field='account_number')
