Re: stop repetition in template
I like your second solution a lot better than mine. I've never seen {%
ifchanged %} used properly before.

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 %}

Re: stop repetition in template
I would handle this at the views layer. Right now your queryset of
college_list is a list of colleges containing cities. In your view code I
would re-organize it to be a list of cities that contain colleges. Then you
can iterate through cities and get colleges. You can build this data
structure dynamically in the view code without explicitly pre-defining it as
a class or model.
Hope this helps.
