class UserProfile(AbstractBaseUser, PermissionsMixin):
username = models.CharField("用户名", max_length=32, unique=True)
is_staff = models.BooleanField(('staff status'), default=False, help_text=("是否可以登录到管理站点"))
is_active = models.BooleanField(default=True, help_text=("是否激活"))
nickname = models.CharField("昵称", max_length=32)
avatar = models.ImageField("头像", upload_to="UA", default='UA/default.jpg')
gender = models.CharField("性别", choices=(("male", "男"), ("female", "女")), max_length=8, null=True, blank=True)
birthday = models.DateField("生日", null=True, blank=True, help_text="日期格式：YYYY-MM-DD，相当于Python中的datetime.date()实例")
email = models.EmailField("邮箱", max_length=255, null=True, blank=True) # EmailField:字符串类型，Django Admin以及ModelForm中提供验证机制
date_joined = models.DateTimeField("加入日期", auto_now_add=True)

USERNAME_FIELD = 'username'  # 你必须指定用户名
# REQUIRED_FIELDS = []  # 还可以指定必填字段

class Meta:
    db_table = 'user'  # 指定数据库中的表名称
    verbose_name_plural = '用户信息'  # 管理站点中显示的表名称

迁移数据后，你会发现数据库表字段中的前3个字段为：password、last_login、is_superuser

不必惊慌，这是Django做的，认证系统中会用到这3个字段

最后，在settings.py文件中指定此类：

# AUTH_USER_MODEL = 'App名称.UserProfile'

    return self.username  # 该返回值会作为认证方法authenticate()的返回值
