Python 如何进入pdb诊断生产服务器上的此错误？编程错误（1110，“列和关于和指定两次”；

如果您询问如何进入pdb，请在代码中要放入调试器的位置添加以下行：

if 'bnewaccount' in request.POST.keys():  
         form1 = OpenidRegisterForm(request.POST)  
         if form1.is_valid():  
             next = clean_next(form1.cleaned_data.get('next'))  
             is_redirect = True  
             tmp_pwd = User.objects.make_random_password()  
             user_ = User.objects.create_user(form1.cleaned_data['username'],  
                      form1.cleaned_data['email'], tmp_pwd) ### this is the last evaluated line in my code  

             # make association with openid  
             uassoc = UserAssociation(openid_url=str(openid_),  
                     user_id=user_.id)  
             uassoc.save()  

如果您需要知道如何在生产服务器上安装stdout，我不知道

if 'bnewaccount' in request.POST.keys():  
         form1 = OpenidRegisterForm(request.POST)  
         if form1.is_valid():  
             next = clean_next(form1.cleaned_data.get('next'))  
             is_redirect = True  
             tmp_pwd = User.objects.make_random_password()  
             user_ = User.objects.create_user(form1.cleaned_data['username'],  
                      form1.cleaned_data['email'], tmp_pwd) ### this is the last evaluated line in my code  

             # make association with openid  
             uassoc = UserAssociation(openid_url=str(openid_),  
                     user_id=user_.id)  
             uassoc.save()
