我正在尝试学习django并且在更改模型时会出现错误.我尝试了很多像default = datetime.datetime.now但我不知道如何解决它.
这些是我的模特
来自django.db导入模型导入日期时间
class Candidate(models.Model):
name = models.CharField(max_length=10)
introduction = models.TextField()
area = models.CharField(max_length=15)
party_number=models.IntegerField(default=0)
def __str__(self) :
return self.name
class Poll(models.Model) :
start_date = models.DateTimeField()
end_date = models.DateTimeField()
area = models.CharField(max_length=15)
class Choice(models.Model) :
poll = models.ForeignKey(Poll)
candidate = models.ForeignKey(Candidate)
votes = models.IntegerField(default=0)
当我键入commmand:python mangage.py migrate时,发生此错误
