 def item_approval(request, pk):
         if request.method == "GET":
             product_form = AdminProductForm(request.POST)
             item = ProductVariants.objects.get(item_num=pk)
             variant_images = ProductVariantsImages.objects.filter(product_variant=item)
             print(variant_images)


             product_form = AdminProductForm(instance=product)
             item_form = ProductVariantsForm(instance=item)
             variant_images = ProductVariantsImagesForm(instance=product_variant_images)# here I get multiple objects
             print(variant_images)



             return render(request, 'loom_admin/product_details.html',
                        {'item_form':item_form, 'product':product,
                        'product_form':product_form,
                        'variant_images':variant_images,
                        })
    

while running I get 'QuerySet' object has no attribute '_meta' when I put variant_images = ProductVariantsImagesForm(instance=product_variant_images[0]) the error disappear. But I am getting first image object. What if I want to do to get multiple images that related to the filter query in django template?

CodePudding user response：

You can use a for loop in your template HTML. for example >>

{% for image in variant_images %}
    <li> {{ variant_images.image }} </li>
     {% endfor %}

something like this will show you the list of images

CodePudding user response：

Rename this:

in views.py

variant_images = ProductVariantsImagesForm(instance=product_variant_images)

to:

variant_images_form = ProductVariantsImagesForm(instance=product_variant_images)

You have the same names, and you end up with the wrong thing.
