## So Person has Orders, Orders has Items
I am trying to list all persons, their orders, ond items:
e.g. Jonh Doe Order #1 Apples Order #2 Grapes
Figs DatesMay Jane Order #1 Pencils Notepads
Pens Colored postitsHenry James Fish Beans
So for loops: For person in person in object_list: ? First_name
For orders( of a person ) For items ( of this order )
endfor endfor endforhere is my list.html template
{% block title %}List{% endblock %}{% block body %}<h1>Current List of
Buyers</h1><ul> {% for person in object_list %} <li>{{
person.first_name }} {{ person.last_name }} <br>{{ person.company}} , {{
person.email }} <br>{{ person.address}} , {{ person.address1 }} <br>{{
person.city }} , {{ person.state }} , {{ person.zip_code}} * {%
johnhorders=Order.objects.filter(person__first_name='John') %}*
{% for order in johnorders %} <br> {{ order.po}}
{{order.date }} {{order.expected}} </ul> <a href="{%
url 'update' order.id %}">Update order information <a href="{% url
'delete' order.id %}">Delete this order</a> {% endfor%} <a
href="{% url 'update' person.id %}">Update information <a href="{% url
'delete' person.id %}">Delete this buyer</a> </li> <br> {%endfor%}</ul>{%
