在旧版本的 Django 中，您可以扩展 User 模型并创建 UserProfile。现在看来，在Django 1.8中，这几乎不再相同了。我正在寻找在Django 1.8中执行此操作的好示例。

这是我在网上某处找到的一个示例，但它没有扩展任何内容。我只想扩展用户，以便我仍然可以在我的模板等中使用用户对象。

class MyUser(AbstractBaseUser):
    """
    Custom user class.
    """

    GENDER_CHOICES = (
        ('M', 'Male'),
        ('F', 'Female'),
    )
    email = models.EmailField('email address', unique=True, db_index=True)
    is_staff = models.BooleanField('is staff', default=False)
    first_name = models.TextField('first name', default=None, null=True)
    last_name = models.TextField('last name', default=None, null=True)
    date_of_birth = models.DateField('date of birth', null=True)
    avatar = models.ImageField('profile picture', upload_to='static/media/images/avatars/', null=True, blank=True)
    has_picture = models.BooleanField('has profile picture', default=False)
    adult = models.BooleanField('is adult', default=False)
    gender = models.CharField('gender', max_length=1, choices=GENDER_CHOICES)

    objects = MyUserManager()

    REQUIRED_FIELDS = ['date_of_birth', 'gender']

    USERNAME_FIELD = 'email'

    # Insert a lot of methods here

    def set_avatar(self):
       self.has_picture = True

使用以下 decoumentation：https ://docs.djangoproject.com/en/1.6/topics/auth/customizing/#extending-django-s-default-user

给了我所有这些错误：
