problem with JSON

class Index(TemplateView):
    def get(self,request):
        form = OrderModelForm
        return render(request, 'index.html', {'form':form})
    def post(self,request):
        url = request.POST.get('url')
        user_mail = request.POST.get('email')
        current_order = OrderModel.objects.create(url = url, email=user_mail)
        current_order.save()

        json_data = json.dumps(request.POST)
        start_parsing.delay(request, url=url, user_mail=user_mail, order_number=current_order.pk)

        return render(request, 'thanks.html', {})
