python - 异常: invalid literal for int() with base 10: ''

Question

我正在使用模型来保存用户信息，例如个人资料图片和个人简介等，但是当我注册时会发生此错误。这是代码

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete='CASCADE')
    description = models.CharField(max_length = 500, default='', blank = True)
    city = models.CharField(max_length = 100, default='', blank = True)
    website = models.URLField(default='', blank = True)
    phone = models.IntegerField(default='', blank = True)
    image = models.FileField()

@receiver(post_save, sender = User)
def create_profile(sender, instance, created, **kwargs):
        if created:
            UserProfile.objects.create(user=instance)
        instance.userprofile.save()

Answer 1

invalid literal for int() with base 10: ''

表示不能做Type Conversion上'' .

我想phone = models.IntegerField(default='', blank = True)这是问题所在。

因为你没有给 phone 赋值，所以它使用默认值 '' ，不能通过 int() 进行转换在Python中。
