When you try to get self.related_items in _get_related_items(), it accesses your new property, which calls _get_related_items(), and so on. This has nothing to do with Django, it's just a Python thing. I'd just call the _get_related_items() method directly and change the name: def active_related_items(self): return self.related_items.exclude(active=0) If you're really set on accessing related_items through the property as you've got it written, just change the name of the original field to all_related_items or something so there's no name collision.
