Django 扩展用户以添加配置文件\u pic

在Django的旧版本中，您可以扩展用户模型并创建用户配置文件。现在看来，在Django 1.8中，这已经不一样了。我在Django 1.8中寻找这样做的好例子

这是我在网上找到的一个例子，但它没有扩展任何内容。我只想扩展用户，这样我就可以在我的tempaltes中使用user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

使用以下方法进行剥除：

给了我所有这些错误：
