If I understand you correctly, you (for example) have a quicktime1, in reel1
and reel2. In reel1 it is the first of, says 5 quicktimes, and in reel2 it
is the third of 4?
The best solution that appears to me is an extra column in the intermediary
table.
See:
http://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships
Here you could specify a field called order.
To display you select everythong from the intermedirary model
'grouped_by=reel, order_by=order'.
Does this make any sense :D?
