views.py登录数据处理

def login(request):

    else:

models.py中auth权限表添加一个字段

class Auth(models.Model):
    url = models.CharField(max_length=32, blank=True, null=True, verbose_name="路径")
    name = models.CharField(max_length=32, blank=True, null=True, verbose_name="显示")
    group = models.ForeignKey(to='AuthGroup', blank=True, null=True, verbose_name="权限组", related_name="authgroup")
    to_display = models.ForeignKey(to='Auth', blank=True, null=True, verbose_name="显示", related_name="authtoauth")

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = "权限表"
