django模型

一、安装数据库，选择server only 一路下一步
二、连接数据库遇到的问题

• 修改setting文件

DATABASES = {
    ‘default‘: {
        ‘ENGINE‘: ‘django.db.backends.mysql‘,
        ‘NAME‘:  ‘djangopro1db‘,
        ‘USER‘: ‘XXX‘,
        ‘PASSWORD‘: ‘XXX‘,
        ‘HOST‘: ‘127.0.0.1‘,
        ‘PORT‘: ‘3306‘
    }
}

• python manage.py makemigrations遇到问题

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.

安装django版本django3.0.3，python3.8，Python3中没有MySQLdb这个模块。查了下百度，

pip install pymysql

project.__init__.py加入

import pymysql
pymysql.install_as_MySQLdb()

再执行，报错

File "C:\Python38\lib\site-packages\django\db\backends\mysql\base.py", line 37, in <module>
    raise ImproperlyConfigured(‘mysqlclient 1.3.13 or newer is required; you have %s.‘ % Database.__version__)
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.

修改 C:\Python38\lib\site-packages\django\db\backends\mysql\base.py，注释以下两行，连接成功。

#if version < (1, 3, 13):
#    raise ImproperlyConfigured(‘mysqlclient 1.3.13 or newer is required; you have %s.‘ % Database.__version__)
