Hm, I think the functionality to do this -- at least if I understand correctly what I read here: http://stackoverflow.com/questions/1113096/django-dump-data-for-a-single-model
I'd be fine dumping the data for the entire app -- but the reason I did it this way is because when I do this, the category_id field is empty for all parts in the Part table. If I look at the database contents, it should not be blank -- so not sure why that's happening. So that's why I wanted to delve deeper... So maybe my actual question should be why is the category_id many-to-many field showing up blank consistently when I do a dumpdata??
