Этот код связан с запросом рекомендации по продукту, в котором пользователь может загрузить столько фотографий, сколько пожелает, для своего запроса рекомендации. Есть две формы: одна для фотографий, другая для описания и номера запрашиваемого товара. Когда я хочу иметь несколько изображений, что мне делать, потому что таким образом сохраняется только изображение, и оно связано с последней формой, загружаемой Ajax.

Я пробую это
Image.objects.create(rejected_product=rejected_product, file=request.FILES['image'])
и это
for image in request.FILES:
Image.objects.create(rejected_product=rejected_product, file=image)
