在Django项目中创建superu出现django.db.utils.IntegrityError: (1062, “Duplicate entry ‘‘ for key ‘mobile‘“)报错
The above exception was the direct cause of the following exception:

django.db.utils.IntegrityError: (1062, "Duplicate entry '' for key 'mobile'")
问题分析:
众所周知我们创建后台管理员时候是没有设置手机号的
报这个错就是告诉我们在数据库中已经存在一个管理员,且手机号为空,
我们再次创建管理员就会有手机号重复的现象存在从而报这个错
同样出现以下问题则是 username不能重复
django.db.utils.IntegrityError: (1062, "Duplicate entry 'gkate' for key 'username'")
