I am getting error when trying to update objects from False to True. here is my code:

class ListNoti(LoginRequiredMixin,ListView):
      raise_exception = True
      model = Notifications
      template_name = 'notifications/notifications.html'
      def get_context_data(self, **kwargs):
          data = super(ListNoti,self).get_context_data(**kwargs)
          data['noti'] = Notifications.objects.filter(receiver=self.request.user,is_seen=False).order_by('-date').update(is_seen=True)
          return data
.update(is_seen=True) raising this error TypeError at /notification/ 'int' object is not iterable
              
KenWhitesell I solved this issue after using queryset in my views. here is my full code:
class ListNoti(LoginRequiredMixin,ListView):
      raise_exception = True
      model = Notifications
      template_name = 'notifications/notifications.html'
      def get_queryset(self):
        data =   Notifications.objects.filter(receiver=self.request.user).update(is_seen=True)
        return data
      def get_context_data(self, **kwargs):
          data = super(ListNoti,self).get_context_data(**kwargs)
          data['noti'] = Notifications.objects.filter(receiver=self.request.user)
          return data
I am not understanding why filter was not working in get_context_data?
