title: Django get_queryset return custom variables
body: <p>Using users as an example I am trying to show how many users there are. <code>get_context_data</code> works totally fine but <code>get_queryset</code> does not. I know that it's not set up properly but I've been playing around with it for quite some days and something is just not clicking..</p>
  
  <p>The main goal is to use the <a href="https://django-filter.readthedocs.io/en/stable/" rel="nofollow noreferrer">Dajngo-Filter</a> form and then be able to get the updated number of user count. I've only found endless documentation on how to show the "list" of users. Which I have done but no documentation on how to show custom variables. I have many statistics &amp; charts I'd like to calculate based on the filters applied.</p>
  
  <pre><code>class UserFilterView(LoginRequiredMixin, FilterView):
      template_name = 'community/user_list.html'
      model =  User
      filterset_class = UserFilter
  
      def get_queryset(self):
          user_count = User.objects.all().count()
  
      def get_context_data(self, *args, **kwargs):
          context = super(UserFilterView, self).get_context_data(*args, **kwargs)
          context['user_count'] = User.objects.all().count()
          return context
  </code></pre>
