django 自定义用户身份验证

实现自定义用户创建admin管理员

配置 settings.py：

# admin管理默认
AUTH_USER_MODEL = 'web.Account'

数据库 models.py:

class MyUserManager(BaseUserManager):
    def create_user(self, email, name, password=None):
        """

        birth and password.

        user = self.model(
            email=self.normalize_email(email),
            name=name,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

urls.py

from django.conf.urls import url

用户登录验证

views.py

from django.shortcuts import render, redirect, HttpResponse
