BBS登入和数据库迁移部分

setting中的设置

auth组件用的user表不再是原来的user表了，应该是现在指定的表（以后没有auth_user表了）
AUTH_USER_MODEL = 'blog.UserInfo'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'zhou1',
        'USER': 'root',
        'PASSWORD': 'admin',
        'PORT': 3306,
        'HOST': '127.0.0.1',
    }
}

数据库迁移部分

from django.db import models
from django.contrib.auth.models import AbstractUser


# Create your models here.
# UserInfo这个表,继承AbstractUser,因为要用auth组件

class UserInfo(AbstractUser):
    nid = models.AutoField(primary_key=True)

    # username=models.CharField(max_length=32,unique=True)
    # 该字段可以为空,为该字段设置默认值,default='123455666'
    phone = models.CharField(max_length=32,null=True)
    # upload_to需要传一个路径
    avatar = models.FileField(upload_to='avatar/', default='/static/img/default.png')
    #  一对一关联blog表,to_field如果不写,默认主键
    # blog_id字段存的数据是什么?blog表的---nid这个字段
