def clean_emailid(self):
    rcvd_mailid = self.cleaned_data.get('emailid')

        qs_count=user_qs.count()

def register_view(request, template_name="index.html"):
    if request.method=="POST": 
       user_values=new_register(data=request.POST)
       if user_values.is_valid():
           user_values.save()
           return HttpResponseRedirect(reverse("url_indexpage"))
       else:
           return render(request, template_name,{'form':user_values})
    elif request.method=="GET":
       user_values=new_register()
       return render(request, template_name,{'form':user_values})

我在段落标记中收到错误消息，但我无法在隐藏字段中收到错误消息。它变得不确定。这有什么不对吗？任何人都可以帮忙吗？请！
