django 修改默认的user表和默认的认证系统

django的功能非常强大,但是自带的user表很多情况下并不满足我们的需求,因此我们需要修改其默认的user表,并且把用username登录改成用email登录

 

第一步,创建自己的user表,在创建的app下的models中

 

 

from django.contrib.auth.models import AbstractUser

from django.db import models

# Create your models here.

 

 

class UserProfile(AbstractUser):

nick_name = models.CharField(max_length=50, verbose_name='昵称', default='')

birthday = models.DateField(null=True, blank=True, verbose_name='生日')

gender = models.CharField(max_length=6, choices=(('male', '男'), ('female', '女')), default='female', verbose_name='性别')

address = models.CharField(max_length=100, default='', verbose_name='地址')

mobile = models.CharField(max_length=11, null=True, blank=True, verbose_name='手机号')

image = models.ImageField(max_length=100, upload_to='image/%Y/%m', default='image?default.png', verbose_name='头像')

  class Meta:

  verbose_name = '用户信息'

  verbose_name_plural = verbose_name

  def __str__(self):

  return self.username

 

因为django的user表也是继承自AbstractUser,所以我们也这样做

 

然后修改下setting,添加

 

# UserProfile 覆盖了 django 内置的 user 表

AUTH_USER_MODEL = 'users.UserProfile'

appname.userProfile

 

接着修改认证系统

 

 

from django.contrib.auth import authenticate, login, logout

from django.contrib.auth.backends import ModelBackend

from django.db.models import Q

from models import UserProfile

 

# 让用户可以用邮箱登录

# setting 里要有对应的配置

class CustomBackend(ModelBackend):

def authenticate(self, 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

 

记得引入models中创建的表

 

# AUTH 方法(支持邮箱登录)

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

setting中加入该方法

 

完成
