1、在app的models.py中添加以下代码：
from django.db import models # Create your models here. # Register your models here. class UserType(models.Model): 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',on_delete=models.CASCADE,)
