django 使用邮箱登录

# 前提

   继承 django 自带的用户类(AbstractUser)

# 环境

  1. python: 3.6.x

  2. django==1.11.22

# apps/users/models.py

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


# Create your models here.

class UserProfile(AbstractUser):
    """
    用户
    """
    gender_choice = (
        ("1", "男"),
        ('0', "女"),
    )

    email = models.EmailField(verbose_name='邮箱', max_length=255, unique=True)
    phone = models.CharField(verbose_name="手机号码", max_length=50, null=True, blank=True)
    avatar = models.URLField(verbose_name="用户头像", default="http://photo.xxx.top/avatar_default.png")
    gender = models.CharField(max_length=32, choices=gender_choice, default="男", verbose_name="性别")
    time_black = models.DateTimeField(verbose_name="下次可访问时间", blank=True, null=True)
    last_ip = models.GenericIPAddressField(verbose_name="上次访问IP", default="0.0.0.0")

    class Meta:
        verbose_name = "用户信息"
        verbose_name_plural = "用户信息列表"

    def __str__(self):
        return "%s-%s %s" % (self.username[0].upper(), self.last_name, self.first_name)

# apps/users/views.py(不局限于邮箱,也可以改成 手机号码等等)

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


# Create your views here.


# 让用户可以用邮箱登录
# setting 里要有对应的配置 AUTHENTICATION_BACKENDS
class CustomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = UserProfile.objects.get(Q(username=username) | Q(email=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None

# settings.py

ALLOWED_HOSTS = ["*"]

AUTH_USER_MODEL = 'users.UserProfile'

AUTHENTICATION_BACKENDS = (
    'apps.users.views.CustomBackend',  # AUTH 方法(支持邮箱登录),CustomBackend 的路径
)
