错误：
django.db.utils.OperationalError: (1366, "Incorrect string value: '\xE6\x96\x87\xE7\xAB\xA0...' for column 'name' at row 9")
解决方法：
进入mysql命令行
mysql> show variables like '%char%';
+--------------------------+-----------------------------------------------------------+
| Variable_name | Value |
+--------------------------+-----------------------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/local/mysql-5.7.21-macos10.13-x86_64/share/charsets/ |
如上，其中的编码有latin1的所以需要修改latin1为utf8，以下是mac中的修改办法
vim /etc/mysql/my.cnf
添加如下内容
[client]
default-character-set =utf8
[mysql]
default-character-set =utf8
[mysqld]
collation-server = utf8_unicode_ci
init_connect ='SET NAMES utf8'
character_set_server=utf8
然后重启mysql服务 并且 删除原先创建的数据库，重新创建
