        elif ("_send-bulk-email" in self.request.POST) and self.request.POST["_self-bulk-email"] == "Send Bulk Email":
        elif ("action" in self.request.POST) and self.request.POST["action"] == "Save Tin":
            user_id = self.request.POST.get('user_id')
            tin = self.request.POST.get('tin_value')
            tin_type = self.request.POST.get('tin_type')
            input_name = f"tin_value_{{ user.id }}"
            if input_name in self.request.POST:
                tin_value = self.request.POST[input_name]
                user = CustomUser.objects.get(id=user_id)
                user.seller_tin = tin
                user.tin_type = tin_type
                user.save()
            context = {'user_contexts': user_contexts}
            return render(self.request, 'admin/generate_form.html', context)
        elif ("_send-tin-email" in self.request.POST) and self.request.POST["_send-tin-email"] == "Send Email":
            user_id = self.request.POST.get('user_id')
            user_name = self.request.POST.get('user_name')
            email_mess = {"seller": user_name}
