default是什么值？自增长的话不需要对id设值啊

来自酷炫的 CNodeMD

@zhangmingfeng 但是 sequelize 默认会把自增长的主键设置 default的呀

apps表的id是auto_increment的吗？

define里面也要把autoIncrement设置为true

主要还是要看表的主键是不是自增的

@sjnho 这样的

@burning0xb 这样设置是自增长的吧？

好吧 是数据库的问题

原来mysql的配置 my.cnf是

就好了，但是我还是不知道为什么就好了–！

原因是 数据库设置了 sqlmode 为 NO_AUTO_VALUE_ON_ZERO

@jinceon 的确是这样的 当时找了好久没有这方面资料，多谢了
