Does this work: pr = pr + a['choice'].price.name ? I would suggest that you change the name of that field ... "name" does not really convey that this is the value of the price - it sounds more like a label for it (like "SuperSaver"). Perhaps you could get rid of the Price class altogether? If it just holds an integer, you could use an IntegerField directly in Choice ...
