http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#inclusion-tags

# view.py

@register.inclusion_tag('children.html')
def children_tag(person):
    children = person.children.all()
    return {'children': children}

# children.html

<ul>
    {% for child in children %}
    <li> <a href="{{ child.get_absolute_url }}">{{ child }}</a></li>
        {% if child.children.count > 0 %}
