Question

我尝试保存模型的m2m关系。这最终会出现在下面看到的模型中。我得到的错误是：

save() got multiple values for keyword argument 'force_insert'

所以对我而言，似乎force_insert在args和kwargs中传递。但是，在使用pdb检查值时，我会得到以下信息：args = ()和kwargs = {'force_insert': True, 'using': 'default'}。所以在args中不存在force_insert。任何想法为什么会出错？

class TaggedItem(GenericTaggedItemBase, TaggedItemBase):
    """
    Also caches team info when available.
    """
    team = models.ForeignKey(Team, null=True)

    def save(self, *args, **kwargs):
        if hasattr(self.content_object, 'team'):
            self.team = self.content_object.team

        import pdb; pdb.set_trace()

        super(TaggedItem, self).save(self, *args, **kwargs)

    class Meta:
        verbose_name = _("Tagged Item")
        verbose_name_plural = _("Tagged Items")

编辑：正如预期的那样，如果我从kwargs中删除'force_insert'，则保存确实有效。

您致super的电话已关闭。您不应该将self传递给方法。这已经由super涵盖了。请改用：

super(TaggedItem, self).save(*args, **kwargs)

Django save（）错误
