from django.contrib.auth.models import User
user =  User.objects.create_user() # 创建用户
superuser = User.objects.create_superuser() # 创建超级用户

from django.contrib.auth import authenticate
user = authenticate(username=username,password=password) -> User | None

user.set_password() # 修改密码

# view.py
from django.contrib.auth import login
login(request, user) # 登录保持
logout(request) # 登录状态取消

from django.contrib.auth.decorators import login_required
@login_required
def view(request):
    login_user = request.user

扩展字段

  • 需要在第一次migrate前进行
  • 添加新的应用
  • 定义模型类继承AbstractUser
  • setting.py中指明AUTH_USER_MODEL = ‘应用名.类名’
