You don't show us ProductForm but I can guess it is a ModelForm for
Product. A ModelForm is designed to display and let you edit one individual
object from the DB, not multiple. Thus the 'instance' parameter to a model
form is supposed to be one single instance of a model, not a QuerySet. A
model formset might be closer to what you are looking for:
