Why do you want to do this in the view ??? If it's for rendering
purpose - which I guess is the case - just pass the appropriate
Category queryset to your context, then do the loop in the template,
ie:
# yourapp/views.py
def category_list(request, ...):
context = dict(categories = Category.objects.all().select_related
())
return render_to_response(
"yourapp/category_list.html",
context,
context_instance=RequestContext(request)
)
# yourapp/category_list.html
<ul>
{% for category in categories %}
<li>
<b>{{ category.name }}</b>
<ul>
{% for subject in category.subject_set.all %}
<li>{{ subject.name }}</li>
{% endfor %}
</ul>
</li>
{% endfor %}
</ul>
HTH - Or did I miss the point ?
