Django(博客系统)：重写了auth.User后使用createsupperuser出错解决办法

背景：重写django的系统User后,使用createsupperuser创建用户失败

由于项目需要扩展django默认新的auth.User系统（添加两个字段：头像、简介等字段），因此就重写了django的默认User类，重写后使用createsupperuser死活创建不了supperuser，提示以下错误：

E:\Work\django\myblog>manage.py createsuperuser --username=joe --email=joe@examp
le.com

E:\Work\django\myblog>python manage.py createsuperuser --username=joe --email=jo
e@example.com
Password:
Password (again):

解决方案，在mange.py shell中执行代码：

>>> from vmaig_auth.models import VmaigUser
>>> user=VmaigUser.objects.create_superuser('admin','emailname@demon.com','new.1234')
