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.*
