Initial for data should be a something that is, or at least behaves like, a sequence of dictionaries. A queryset is behaves like a sequence, but the elements of that sequence don't behave like dictionaries (they're objects -- in this case, Parent objects). So whilst, "for key in obj:" works when "obj" is a dictionary, it doesn't work when "obj" is a Django Model subclass (e.g. a Parent). Since the requirement is to pass in a list of dictionaries, using the values() method on your inlinedata call will get you a long way there.
