name = models.CharField(max_length=32)
class UserInfo(models.Model):
username = models.CharField(max_length=32)
pwd = models.CharField(max_length=32)
email = models.CharField(max_length=32)
user_type = models.ForeignKey(UserType)

'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',

- 然后在Terminal 运行以下命令:
(python manage.py makemigrations)
(python manage.py migrate)
(python3) C:\Users\Administrator\PycharmProjects\s14django>python manage.py makemigrations
Migrations for 'cmdb':
cmdb\migrations\0001_initial.py:
- Create model UserInfo
- Create model UserType
- Add field user_type to userinfo
(python3) C:\Users\Administrator\PycharmProjects\s14django>python manage.py migrate
