今天碰到了一个很灵异很灵异的事情！各种找不到原因！但就是一筹莫展！
新建了一个django项目，安装了xadmin（感觉跟这个无关）
反正想要执行更新数据库的命令，只要一执行 ：python manage.py migrate
就会一坨长代码块！关键报错信息跟数据一点关系都没有啊！model里也没有新增跟时间有关的字段啊！真是没办法了，请走过路过的大神，千千万万给我指点一下，我到底是哪里弄错了……跪谢跪谢！

既然提示日期格式有问题. 你就打开yanzheng.0002_auto_20180501_1656...这个文件看看, 语句中有没有日期格式的问题

嗯嗯，我将makemigrations目录下除了构造文件，全删了，再执行数据更新命令就好了……
