django-重写登录认证（可以使用用户名或手机号登录）

1、首先在setting.py文件整增加

AUTHENTICATION_BACKENDS =('study.views.CustomBackend',)

2、重写代码

from django.contrib.auth.backends import ModelBackend
from django.db.models import Q
from .models import UserInfo

class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = UserInfo.objects.get(Q(username=username)|Q(mobile=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None
