two different solutions, depending on what do you want:
A) if you only need the cities from a given college queryset, in the
view do something like:
render_to_response(
'college/list.html',
{'cities_list':City.objects.filter(college_set__in = college_list)}
)
B) if you want a list of colleges, separated by city, and only show
the city once for each group of colleges:
in the view:
return render_to_response(
'college/list.html',
{'list':college_list.order_by('city')}
)
in the template:
{% for college in list %}
{% ifchanged %}{{college.city}}{% endifchanged %}
{{college.name}}
{% endfor %}
