2.运行“makemigrations”和“migrate”时报错“1366, "Incorrect string value”是因为mysql编码问题导致，

mysql> show variables like "%char%";

关闭mysql
MAC电脑需要在“/private/etc”中新建“my.cnf”文件（如果已有则不需要新建），添加以下数据

[client]   
default-character-set=utf8    
[mysqld]
character-set-server=utf8

打开mysql验证

mysql> show variables like "%char%";
