In the below code, I'm saved my recent data in model and create a dictionary order = order.save() because I can use this in my template. When I run the code the order is having ```None`` value.

What i can do for it.

     def post(self, request, product_id):
          product = Product.objects.get(id=product_id)
          if request.POST['address'] and request.POST['quantity']:
               order = Order()
               order.or_proName = product.pro_name
               order.or_companyName = product.companyName
               order.or_quatity = request.POST['quantity']
               order.or_quatity = int( order.or_quatity)
               orderPrice = order.or_quatity*product.Sale_Price
               order.or_bill = 100 + orderPrice
               order.pub_date = timezone.datetime.now()
               product.Quantity -= order.or_quatity
               product.save()
               order = order.save()
               args = {'order':order}
               return render(request, self.red_templateName, args)

You should not assign the result of the .save() function to order, since that is indeed None. Just .save() the order, and use the order function further in your view:

def post(self, request, product_id):
    product = Product.objects.get(id=product_id)
    if request.POST['address'] and request.POST['quantity']:
        order = Order()
        order.or_proName = product.pro_name
        order.or_companyName = product.companyName
        order.or_quatity = request.POST['quantity']
        order.or_quatity = int( order.or_quatity)
        orderPrice = order.or_quatity*product.Sale_Price
        order.or_bill = 100 + orderPrice
        order.pub_date = timezone.datetime.now()
        product.Quantity -= order.or_quatity
        product.save()
        order.save()
        args = {'order':order}
        return render(request, self.red_templateName, args)

You should however define an else case as well, since the post method is supposed to always return a HttpResponse object, for example an error mesage.
