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

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.*
