ok, thanks, that helped me figure out a solution. here's what i added
to admin.py within my Sales class. i can then access 'cl.amount_sum'
from my pagination.html template. anything wrong with how i did this?
i'll admit i don't fully understand all that is happening here.
==============
def changelist_view(self, request, extra_context=None, **kwargs):
from django.contrib.admin.views.main import ChangeList
cl = ChangeList(request, self.model, list(self.list_display),
self.list_display_links, self.list_filter,
self.date_hierarchy, self.search_fields,
self.list_select_related,
self.list_per_page,
self.list_editable,
self)
cl.formset = None
q = cl.query_set.extra(select={'amount_sum': 'SUM(amount)'})
cl.amount_sum = q.all()[0].amount_sum
if extra_context is None:
extra_context = {}
extra_context['cl'] = cl
return super(SalesAdmin, self).changelist_view(request,
extra_context=extra_context)
