Hi! I have some Django Model which has two properties: class M(Model): @property def p1(self): return process_result(SomeModel.objects.filter(val_gt=1))
@property def p2(self): return process_result(SomeModel.objects.filter(val_lt=1)) And both used in Django Admin list_lisplay = ('p1','p2',) I want to replace 2 database queries with 1, something like this class M(Model): def some_hook(self): res = SomeModel.objects.all() self.p1 = process_result(filter(lambda l:l.val > 10, res)) self.p2 = process_result(filter(lambda l:l.val < 10, res)) PS: problem with >10 or <10 is just an example for simplification, I am only trying to find a way how to define *multiple properties* with performing *one common database query* Thanks -- You received this message because you are subscribed to the Google Groups "Django users" group.
