I am doing CRUD using serializers as I am tasked.

In this context I am new to images and studied it,I have made files called 'media' to store images but I am getting an error like this

I have been trying to solve this error but didnt have much success

below is the insert function

def insert(request):
    data = {}
    if request.method == "POST":
        print('POST',id)
        data['categories'] = request.POST.get('categories')
        data['sub_categories'] = request.POST.get('sub_categories')
        data['color'] = request.POST.get('color')
        data['size'] = request.POST.get('size')
        data['title'] = request.POST.get('title')
        data['price'] = request.POST.get('price')
        data['sku_number'] = request.POST.get('sku_number')
        data['product_details'] = request.POST.get('product_details')
        data['quantity'] = request.POST.get('quantity') 
        data['image'] = request.FILES['images']
        form = POLLSerializer(data=data)
        print(form)
        if form.is_valid():
            print('form after valid:',form)
            print("error of form:",form.errors)
            form.save()
            
            messages.success(request, "Record Updated Successfully...!:)")
            return redirect("polls:show")
        else:
            print('form not valid')
            print(form.errors)
    if request.method == "GET":
        print('POST',id)
        category_dict = Categories.objects.filter(isactive=True)
        category = CategoriesSerializer(category_dict, many=True)
        sub_category_dict = SUBCategories.objects.filter(isactive=True)
        sub_category = SUBCategoriesSerializer(sub_category_dict,many=True)
        color_dict = Colors.objects.filter(isactive=True)
        color = ColorsSerializer(color_dict,many=True)
        size_dict = Size.objects.filter(isactive=True)
        size = SizeSerializer(size_dict,many=True)
        hm = {"context": category.data,"sub_context":sub_category.data,"color_context":color.data,"size_context":size.data}
        return render(request, "polls/product_insert.html", hm)

settings

STATIC_URL = 'static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]
MEDIA_ROOT = os.path.join(BASE_DIR,'media/')
MEDIA_URL = '/media/'

where am I going wrong in the code?

CodePudding user response：

data['image'] = request.FILES['images']

It could be that you're reading images instead of image from request.FILES, as to me it seems that data is initialized by the same keys of request.FILES .
