解决Django在mariadb创建的表插入中文乱码的问题

1.确保你的mariadb数据库的character_set_connection、character_set_database、character_set_server的编码均为utf8

MariaDB [(none)]> show variables like "character_set_%";
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

2.如果mariadb数据库不是UTF,请修改以下配置文件的项
/etc/my.cnf
[mysqld]
character-set-server=utf8

[mysql]
default-character-set=utf8

[client]
default-character-set=utf8

/etc/my.cnf.d/server.cnf
[mysqld]
init_connect = 'SET NAMES utf8'
character-set-server = utf8

3.确保创建的数据库编码格式为utf-8
MariaDB [(none)]> show create database django_demo1;
+--------------+-----------------------------------------------------------------------+
| Database | Create Database |
+--------------+-----------------------------------------------------------------------+
| django_demo1 | CREATE DATABASE `django_demo1` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+--------------+-----------------------------------------------------------------------+
1 row in set (0.01 sec)

如果不是，则新建一个编码格式为utf-8的数据库
CREATE DATABASE django_demo1 DEFAULT CHARACTER SET utf8
