Custom Managers

default

Class: ManagerBase

*Base for all managers in AMO.

Returns BaseQuerySets.

If a model has translated fields, they’ll be attached through a transform function.*

Custom Methods

transform(self, fn)

Custom QuerySet

Class: BaseQuerySet

Represent a lazy database lookup for a set of objects.

Custom Methods
get_with_primary_fallback(self, *args, **kwargs)

*Like get(), but if using a non-default database and DoesNotExist is raised, another attempt is made using the default database instead.

Intended to be used in places where replication lag could cause the object not to exist for a brief moment and forcing use of primary db at all times is undesirable.*

no_transforms(self)
only_translations(self)

Remove all transforms except translations.

optimized_count(self)

*Slightly optimized count() for cases where there is a DISTINCT in the queryset.

When a count() call is made on a queryset that has a distinct, that causes django to run the full SELECT (including all fields, distinct, ordering etc) in a subquery and then COUNT() on the result of that subquery, which is costly/innefficient. That’s tracked in https://code.djangoproject.com/ticket/30685. We can’t easily fix the fact that there is a subquery, but we can avoid selecting all fields and ordering in that subquery needlessly.*
