英文:
customize models in Django RestFramework using AbstractBaseUser, BaseUserManager
问题
我想自定义模型，所以我使用了AbstractBaseUser和BaseUserManager。我使用**extra_field来添加'point'属性。
我访问了http://127.0.0.1:8000/account/signup/并输入了我的数据，但出现了错误。
我的代码有什么问题？我是初学者，请帮帮我。

当你使用 ** 解包值时，你应该这样访问这些值：
def create_user(self, email, nickname, name, password=None, **kwargs):
if not email:
raise ValueError('必须提供用户邮箱')
if not nickname:
raise ValueError('必须提供用户昵称')
if not name:
raise ValueError('必须提供用户姓名')
user = self.model(
email = self.normalize_email(email),
nickname = nickname,
name = name,
point = kwargs['point']
)
user.set_password(password)
user.save(using=self._db)
return user
注意我如何获取 point 的值。问题在于你对 point 的定义是 { point: 500 }。所以它是一个字典。你需要从该字典中获取 point 的值。
英文:
When you unpack values using ** then you should access the values like this:
def create_user(self, email, nickname, name, password=None, **kwargs):
if not email:
raise ValueError('must have user email')
if not nickname:
raise ValueError('must have user nickname')
if not name:
raise ValueError('must have user name')
user = self.model(
email = self.normalize_email(email),
nickname = nickname,
name = name,
point = kwargs['point']
)
user.set_password(password)
user.save(using=self._db)
return user
Check how I get the value of point. The thing is that your definition of point is { point: 500 }. So is a dict. You need to get the value of point from that dict.
