问题

利用pycharm在Django项目创建超级管理员时候，出现错误

分析

从最后一句可以发现，错误是由于‘gender’长度过长

解决方法

mac上pycharm全局搜索快捷键command + shift +R 搜索gender
可见
gender = models.CharField(max_length=5,choices=(('male',u'男'),('famale',u'女')),default='female')
female的长度为6，而max_length=5，跟着视频无脑码代码没有思考，这里将5改为10即可。
然后

makemigrations [appname]
migrate [appname]
