Is there a specific reason Djangos QuerySet does not implement __contains__? It doesn't seem very complicated to me, but maybe I'm missing something.
When checking if an object is in e queryset I always use code lite this: if queryset.filter(pk=obj.pk).exists(): The pythonic way would be: if obj in queryset: The way I understand it this latter version will fetch all objects from queryset, while the first one is a much leaner db query. So, is there a reason QuerySet doesn't have a __contains__ method, or would it be a good addition? My guess is that a lot of people use the "obj in queryset" syntax, believing it does "the right thing". //Johan -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
