 Hi guys,
 is this intentional behaviour or not?


 {{{
 class SomeQuerySet(models.QuerySet):
     def active(self):
         print('active')
         data = cache.get(CACHE_KEY)
         if data is None:
             print('no cache')
             data =
 
self.select_related('related').filter(date_expired__gte=timezone.localtime().now()).filter(
                 some__is_active=True).order_by('-date_activated')
             cache.set(CACHE_KEY, data, 30)
         return data

 }}}


 {{{
 class QSSomeListView(ListView):
     queryset = Some.objects.active()
 }}}

 {{{
 class GetQSSomeListView(ListView):
     def get_queryset(self):
         return Some.objects.active()
 }}}

 QSSomeListView never print anything from `active()` method on page access,
 and actually never hit cache. It print only `active` once at project
 startup.

 GetQSSomeListView works as expected.

 If its intentional, could you please explain / point me why so?
 Thank you.
