python（Django）自动化之链接数据库

1、安装数据库

具体安装mysql的教程其实在csdn上都有具体教程大家可以看看

2、更换django的配置

具体是在settings.py中将代码更改成如下：

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

(.venv) PS D:\python project(1)\my_django_2> python manage.py makemigrations
No changes detected
(.venv) PS D:\python project(1)\my_django_2> python manage.py migrate
