How to force Django admin to delete via QuerySet.delete?

Question

Django

There is a model, it has a manager:

class QuerySet(models.QuerySet):
    def delete(self):
        self.update(is_delete=True)


class BaseManager(models.Manager):
    def get_queryset(self):
        return QuerySet(self.model).filter(is_delete=False)

I delete via "delete selected objects" , okay, using QuerySet.delete() .
I delete via POST 127.0.0.1:8000/admin/article/7/delete as I understand it, Model.delete() is used .
