def delete(self):
clone = copy.deepcopy(self)<EOL>return [item.delete() and item for item in clone]<EOL>
Deletes all objects that matches to the queryset.

Note:
    Unlike RDBMS systems, this method makes individual save calls
    to backend DB store. So this is exists as more of a comfortable
    utility method and not a performance enhancement.

Returns:
    List of deleted objects or None if *confirm* not set.

Example:
    >>> Person.objects.filter(age__gte=16, name__startswith='jo').delete()
