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

Posted 2020-10-08 yy

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=[email protected]
le.com

E:\Work\django\myblog>python manage.py createsuperuser --username=joe --email=jo
[email protected]
Password:
Password (again):

E:\Work\django\myblog>

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‘,‘[email protected]‘,‘new.1234‘)

注意：

1）上边我导入的VmaigUser是我系统覆盖django系统User的用户类，因此我使用该类来直接向数据库中插入记录。

2）需要注意：我这里是使用该方案执行时也出现了错误，尽管出现错误，但是去数据一查询发现确实插入用户数据成功了，而且该用户是可以直接登录django后台。
