我嘗試保存模型的m2m關係。這在您看到下面的模型中結束。我得到的錯誤是:Django save()error
save() got multiple values for keyword argument 'force_insert'
所以對我來說似乎force_insert既在args和kwargs通過。但是,當用pdb檢查這些值時,我得到以下結果:args =()
和kwargs = {'force_insert': True, 'using': 'default'}
。所以force_insert不存在於args中。任何想法,爲什麼這會出錯?
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")
編輯:如預期的那樣,如果我從kwargs中刪除'force_insert'則保存無效。

代碼中的m2m關係究竟在哪裏?你能粘貼一個堆棧跟蹤嗎? – Jingo 2012-02-28 14:49:47
可以這麼說,m2m相當遙遠。我將添加一個堆棧跟蹤! – 2012-02-28 15:15:33
