1、新建一個(gè)mysite項(xiàng)目:django-admin startproject mysite?
2、進(jìn)入項(xiàng)目目錄,新建一個(gè)app :?python manage.py startapp polls
3、安裝mysqlclient :pip install mysqlclient

'NAME': 'my_web',
'USER': 'root',
'PASSWORD': 'password',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}
5、執(zhí)行命令:?python manage.py migrate

在數(shù)據(jù)庫中自動(dòng)創(chuàng)建web系統(tǒng)使用到的表

6、編輯polls/models.py文件內(nèi)容
fromdjango.dbimport models
class Question(models.Model):
