Question

我有一个页面，您可以在其中添加产品，添加缩略图以及为产品添加图像。

我正在使用formsets，如下所示。问题是上传到图像formset的图像是否正确上传，但上传到缩略图formset的图像根本没有上传...我可能做错了什么？

def AddProduct(request):

    ImageFormSet = modelformset_factory(ProductImage,
                                        form=ImageForm, extra=4)
    ThumbnailFormSet = modelformset_factory(ProductvThumbnail,
                                        form=ThumbnailForm)

    if request.method == 'POST':

        product_form = AddEditProductForm(request.POST)
        image_formset = ImageFormSet(request.POST, request.FILES, prefix='images', 
                               queryset=roductImage.objects.none())
        thumbnail_formset = ThumbnailFormSet(request.POST, request.FILES, prefix='thumbnail',
                       queryset=ProductThumbnail.objects.none())

        if product_form.is_valid() and image_formset.is_valid() and thumbnail_formset.is_valid():


            product = product_form.save()

            thumbnails = thumbnail_formset.save(commit=False)
            for thumbnail in thumbnails:
                thumbnail.product = product
                thumbnail.save()

            images = image_formset.save(commit=False)
            for image in images:
                image.product = product
                image.save()

            return HttpResponseRedirect('/product/')
        else:
            print (product_form.errors, image_formset.errors, thumbnail_formset.errors)

    else:
        product_form = AddEditProductForm()
        image_formset = ImageFormSet(queryset=ProductImage.objects.none(), prefix='images')
        thumbnail_formset = ThumbnailFormSet(queryset=ProductThumbnail.objects.none(), prefix='thumbnail')

    return render(request, 'product/add.html',
                  {'product_form': product_form, 'image_formset': image_formset,
                   'thumbnail_formset': thumbnail_formset},
                  context_instance=RequestContext(request))

我找到了一个解决方案 - 我的formset看起来很好，问题出在我的models.py中。 ProductThumbnail模型中的ImageField被称为'image = models.ImageField ...'但它应该被称为缩略图 - 这就是没有上传缩略图的原因 - 我的for循环没有找到任何东西。

从两个表单集上传图像 - Django
