How can you perform complex sorting on an object before passing it to the template? For example, here is my view:

@login_required
def overview(request):
   physicians = PhysicianGroup.objects.get(pk=physician_group).physicians

for physician in physicians.all():
	physician.service_patients.order_by('bed__room__unit', 'bed__room__order', 'bed__order')

return render_to_response('hospitalists/overview.html', RequestContext(request,  {'physicians': physicians,}))

The physicians object is not ordered correctly in the template. Why not?

Additionally, how do you index into a list inside the template? For example, (this doesn't work):

{% for note_type in note_types %}
   <div><h3>{{ note_type }}</h3>
   {% for notes in note_sets.index(parent.forloop.counter0) %}
   #only want to display the notes of this note_type!
      {% for note in notes %}
         <p>{{ note }}</p>
      {% endfor %}
   {% endfor %}
   </div>
{% endfor %}
