这是带有回溯的更新代码

这是模型：

class Base(models.Model):
    created_by = models.ForeignKey(User, related_name="(app_label)s_%(class)s_creator")
    edited_by = models.ForeignKey(User, related_name="(app_label)s_%(class)s_editor")
    created_at = models.DateTimeField(auto_now_add=True)
    modified_at = models.DateTimeField(auto_now=True)
     
    class Meta:
            abstract = True
 
class Department(Base):
    dept_id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=60, unique=True)
    description = models.TextField()
 
    def __unicode__(self):
        return str(self.name)

错误回溯：

user创建部门时必须提供 a 。request.user您可以像在视图中一样访问当前用户

user = request.user

或者如果您在 shell 中进行测试，则从数据库中获取任何用户

user = User.objects.get(id=1) # get

然后创建department：

department = Department(name='test',
                        description='test',
                        user=user,
                        )

最后，你default=User.pk是不正确的。对于您可以访问的用户实例user.pk，但 class 属性User.pk不是您可能认为的当前用户的 pk。
