基于 django 自带的用户认证进行用户认证

django admin 默认已经存在了一个用户认证，这个时候可以偷个小懒，直接用 django 自带的，就不需要自己写用户认证了

1、目录结构：

2、代码

在 settings.py 中添加一行

# 如果不添加该行，则在未登录状态打开页面的时候验证是否登录的装饰器跳转到 /accounts/login/ 下面
# 第一种解决方法就是修改 settings.py 中的 LOGIN_URL
# 第二种解决方法是在 url 中匹配该 url
LOGIN_URL = "/login/"

    user = models.OneToOneField(User)   # 跟 django 的 User 表做一个一对一

    name = models.CharField(max_length=)

    roles = models.ManyToManyField("Role", blank=True, null=True)
