Description

I have an admin with filters where one of them is:

Code highlighting: 

class NegatedMyFiledFilter(MyFieldListFilter):
    title = ('excluded Fields')
    parameter_name = 'nonField'

    def queryset(self, request, queryset):
        if self.values():
            queryset_to_negate = super(
                NegatedMyFieldFilter, self
            ).queryset(request, queryset)
            return queryset.difference(queryset_to_negate)

Where MyFieldListFilter is a filter that extends admin.SimpleListFilter
When the above filter is applied(alone or in combination with others) _selected_action is not respected when applying an action and as a result actions get applied to all records, not just the selected ones
As a hack I ended up doing in one of my custom actions :

Code highlighting: 

  qs_ids = queryset.values_list('pk', flat=True)
  selected_ids = request.POST.getlist('_selected_action',qs_ids)
  return TimeSheet.objects.filter(
      pk__in=qs_ids,
  ).filter(pk__in=selected_ids).update(my_flag=True)

but I was expecting the framework to do the second filtering for me
