It could be a number of things, but the main thing that caught my attention
was this part
self.fields['images'].initial = str(selected_image)
self.fields['images'].initial = str(selected_flavor)
shouldn't it be
self.fields['images'].initial = str(selected_image)
self.fields['*flavors*'].initial = str(selected_flavor)
?
