Without more detail, a good place to start would be with the ORM aggregation documentation:
https://docs.djangoproject.com/en/1.7/topics/db/aggregation/#filter-and-exclude I would advise reading the whole page, though. Note that the placement/order of filters are much more significant than with normal ORM queries when using aggregation, but the section I linked to should explain that. -James On Fri, Feb 20, 2015 at 1:08 AM, SHINTO PETER <shinto....@gmail.com> wrote: > How to filter by Group_BY ? > > -- > You received this message because you are subscribed to the Google Groups > "Django users" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to django-users+unsubscr...@googlegroups.com. > To post to this group, send email to django-users@googlegroups.com. > Visit this group at http://groups.google.com/group/django-users. > To view this discussion on the web visit > https://groups.google.com/d/msgid/django-users/3b251918-cc2c-4602-b810-a24485f05a78%40googlegroups.com > <https://groups.google.com/d/msgid/django-users/3b251918-cc2c-4602-b810-a24485f05a78%40googlegroups.com?utm_medium=email&utm_source=footer> > . > > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Django users" group.
