建立django專案後，建立元件manage

安裝pymysql，pip install pymysql

並修改檔案__init__.py

import pymysql 

1. pymysql.install_as_MySQLdb()

找到setting.py,修改設定

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'testchar',
        'USER': 'root',
        'PASSWORD': '',
        'HOST': 'localhost'
 
,
        'PORT': '3306',
    }
}

要從原有mysql資料庫得到models，使用命令

 manage.py inspectdb

得到

貼上到models.py

找到admin.py，註冊模型

from manage.models import Journal,Project,User;


# Register your models here.
admin.site.register([Journal,Project,User])
