I have overloaded delete() method of my model to enable soft deletion so
that delete() method just sets is_deleted field to be true and calls
build-in save() method.
It's working fine against individual model objects:
{{{
my_object = MyModel.objects.get(id=1)
my_object.delete() # Works fine, the object isn't actually deleted.
}}}

But when I called delete() method directly for a queryset, it just hard-
deleted those objects included in the queryset:
{{{
some_objects = MyModel.objects.filter(id__lte=10)
some_objects.delete() # Those objects are actually deleted from the
database.
}}}

Comment:

`Model.delete()` is not called when deleting objects in bulk using
`QuerySet.delete()`, see
[https://docs.djangoproject.com/en/stable/topics/db/models/#overriding-
model-methods "Overriding predefined model methods"] for more details.
