}
报错信息：
Illuminate \ Database \ QueryException (HY000)
SQLSTATE[HY000]: General error: 1364 Field 'avatar' doesn't have a default value (SQL: insert into users (name, email, password, updated_at, created_at) values (李林, entirlyelite@163.com, $2y$10$uUKooScZY.6oOfcEeWju7OX3sVNbpd2/EeFjsdkQnGrJU1fSDUuN., 2018-01-07 03:49:37, 2018-01-07 03:49:37))

报错提示 avatar 不存在默认值 ， 我明明在代码里面写有值，我的做法， 我首先怀疑是不是斜线或者点 系统不认，这种符号数据库写不进去，我把值改成随便的两个字母 ，结果是一样的 ，然后我把头像字段改成允许空，然没有卵用， 麻烦老师，帮看看 ，谢谢你 祝您 新的一年里天天都有好心情
