I suggest an initial implementation of: {{{ def refresh(self, *args, **kwargs): """""" Returns a new QuerySet instance with the args ANDed to the existing set. """""" self._result_cache = None return self }}} Reason this is requested: When I'm using modelformsets I typically find the need to refresh the queryset that is used by the ModelFormset. To do this I perform the following action: {{{ updated_formset = ConciergeUserPoolFormset(request.POST) if updated_formset.is_valid(): updated_formset.save() queryset = updated_formset.get_queryset() # we need an updated queryset, not the cached version. set the results cache to None to force re-fetch queryset._result_cache = None updated_formset = ConciergeUserPoolFormset(queryset=queryset) }}} This is not an obvious solution to the issue of updating a ModelFormset or forcing a queryset update in general, it also uses a private method of the Queryset object which I would prefer to avoid.",New feature,closed,Documentation,1.6,Normal,fixed,,,Ready for checkin,1,0,0,0,1,0
