1.在Django中的models.py建表

from django.db import models from django.contrib.auth.models import AbstractUser # Create your models here. class UserInfo(AbstractUser):     nid = models.AutoField(primary_key=True)     phone = models.CharField(max_length=11, null=True)     avatar = models.FileField(upload_to="avatars/", default="avatar/default.png", verbose_name="头像")     create_time = models.DateTimeField(auto_now_add=True)     blog = models.OneToOneField(to="Blog", to_field="nid", null=True)     def __str__(self):         return self.username class Blog(models.Model):     """     博客信息     """     nid = models.AutoField(primary_key=True)     title = models.CharField(max_length=64)  # 个人博客标题     site = models.CharField(max_length=32, unique=True)  # 个人博客后缀     theme = models.CharField(max_length=32)  # 博客主题     def __str__(self):         return self.title

2.在settings.py中

# 告诉Django项目用哪个APP下的哪儿张表做认证 AUTH_USER_MODEL = 'APP名称.UserInfo'
