Thanks for the suggestions, I will change the name from Model after I can
get this working.
So, I've changed the code using your help to:
{% if category_list %}
{% for category in category_list %}
<li><strong>{{ category }}</strong></li>
<ul>
{% for model in category.model_set %}
<li>
<a href="{{ model.get_absolute_url }}"> {{ model.model_number
}}..........{{ model.description }} </a>
</li>
{% endfor %}
</ul>
{% endfor %}
{% else %}
<p>There is no equipment in the database</p>
{% endif %}
{% endblock %}
However, this just prints "There is no equipment in the database". Am I
missing something? I will try to experiment a little more.
