python（Django）自动化之链接数据库

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'autotest',
        'USER': 'root',
        'PASSWORD': 'chengxian8.8',
        'HOST': '127.0.0.1',
        'PORT': '3306',
    }
}
注意：是更改不是添加

3、更改__init__.py内容

import pymysql
pymysql.install_as_MySQLdb()

4、安装PyMySQL模块

在命令行模式中更换到PyMySQL所在目录下进行安装

pip install PyMySQL

5、迁移同步数据库和表结构
