Fixed #31916 -- Fixed combined queryset crash when combining with ordered combined querysets. 2020-09-17 08:26:06 +02:00
Alexandr Tatarinov f4ac167119 Fixed #27719 -- Added QuerySet.alias() to allow creating reusable aliases. 
QuerySet.alias() allows creating reusable aliases for expressions that
don't need to be selected but are used for filtering, ordering, or as
a part of complex expressions.

Thanks Simon Charette for reviews.
