django扩展用户继承AbstractUser

因为django自带的用户认证系统是通过username、password，已经无法满足现在大多数使用手机号和密码验证的需求，
所以：
A 需要自定义一个User包含手机号
B 需要自定义，通过手机号创建用户的方法
C 修改authenticate通过手机号进行认证

1、在app01/models.py里面创建自定义User

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

class User(AbstractUser):
    telephone = models.CharField(max_length=11, unique=True)
    school = models.CharField(max_length=100)

    USERNAME_FIELD = "telephone"   #USERNAME_FIELD作用，是执行authenticate验证， username参数传入后，实际校验的是telephone字段

在settings.py里面，告诉django不再使用默认的User，使用自定义的User

AUTH_USER_MODEL = 'app01.User'

执行makemigrations和migrate

manage.py@untitled1019 > makemigrations
"D:\Program Files\PyCharm 2018.1.4\bin\runnerw.exe" "D:\Program Files\python3.6.7\python.exe" "D:\Program Files\PyCharm 2018.1.4\helpers\pycharm\django_manage.py" makemigrations D:/pythonWorkspace/untitled1019

manage.py@untitled1019 > migrate

同步完数据库，可以看见 app01_user表里多了两个字段， telephone、school

2、在app01/models.py里面自定义创建普通用户和超级用户的方法

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

class UserManager(BaseUserManager):
    def _create_user(self , telephone, username, password, **kwargs):
        if not telephone:
            raise  ValueError("必须要传递手机号码！")
        if not password:
            raise  ValueError("必须要传递密码")
        user = self.model( telephone = telephone, username= username , **kwargs)
        user.set_password( password )
        user.save()
        return  user

    def create_user(self,  telephone, username, password, **kwargs):
        kwargs['is_superuser'] = False
        return self._create_user( telephone = telephone, username=username, password = password, **kwargs )

    def create_superuser(self, telephone, username, password, **kwargs):
        kwargs['is_superuser'] = True
        return  self._create_user( telephone = telephone, username=username, password = password, **kwargs )

class User(AbstractUser):
    telephone = models.CharField(max_length=11, unique=True)
    school = models.CharField(max_length=100)

    USERNAME_FIELD = "telephone"   #USERNAME_FIELD作用，是执行authenticate验证， username参数传入后，实际校验的是telephone字段

    objects = UserManager()

3、在app01/views.py视图中，调用创建用户和验证用户的方法

from django.shortcuts import render, HttpResponse
from django.db import  connection
from app01.models import User
from django.contrib.auth import  authenticate


def test(request):
    #创建普通用户
    # telephone = "17777677777"
    # password = "444444"
    # username = "zhiliao4"
    # user = User.objects.create_user( telephone=telephone, password=password, username=username)
    # print(user.username)

    #创建超级用户
    # telephone = "19999699999"
    # password = "555555"
    # username = "zhiliao5"
    # user = User.objects.create_superuser(telephone=telephone, password=password, username=username)
    # print(user.username)

    #用户认证
    user = authenticate(request, username="19999699999", password="555555")
    if user:
        print("验证成功")
        print(user.username)
    else:
        print("验证失败")
    return HttpResponse("继承AbstractUser扩展用户")

创建用户的执行结果如下：

验证用户的执行结果如下：
