Django parse_datetime match=datetime_re.match（值）类型错误：应为类似对象的字符串或字节

我有这个模型的错误。py？ 这将取代内置的用户模型

在def UserManager中的user_obj.saveusing=self._db行中检测到错误

和行内def create_superuser user=self.create_user 电子邮件 姓氏=姓氏， first_name=first_name， 密码=密码，

似乎它不喜欢我的带有日期值的timestamp属性？ 谢谢

我发现了这个问题

confirmedDate=models.DateTimeFielddefault=False

它不能是default=false，因为它是一个日期字段。好答案是： confirmedDate=models.DateTimeFieldFull=True，blank=True
