Django:IntegrityError 列 'user_id' 不能为空

Question

在注册时保存我的用户后，我收到以下错误消息。有人可以解释为什么吗？

谢谢

错误信息

IntegrityError at /member/registration/
(1048, "Column 'user_id' cannot be null")
Exception Type: IntegrityError at /member/registration/
Exception Value: (1048, "Column 'user_id' cannot be null")

view.py

 if form.is_valid():
            # If form has passed all validation checks then continue to save member.
            user = User.objects.create_user(
                                            username=form.cleaned_data['username'],
                                            email=form.cleaned_data['email'], 
                                            password=form.cleaned_data['password']
                                            )
            user.save()
            #member = User.get_profile()
            #member.name = form.cleaned_data['name']
            #member.save()
            member = Member(
                            name=form.cleaned_data['name']
                            )
            member.save()

模型.py

class Member (models.Model):
    user =  models.OneToOneField(User)
    name = models.CharField(max_length=100)

    def __unicode__(self):
        return self.name

错误是当您保存成员而不是用户时。创建成员时，您并未分配用户。
