如何复制内联对象来生存？

Question

我是 Django CMS 的新手。我创建了一个带有内联的插件。当我保存插件和发布页面时，模型会被复制，但内联对象不会被复制。

有什么办法吗？当我发布页面时，我希望我的内联对象也保存在活动对象中。

您需要在您的插件上实现一个 copy_relations 方法。文档是 here，但基本上功能是这样工作的；

class ArticlePluginModel(CMSPlugin):
    title = models.CharField(max_length=50)

    def copy_relations(self, oldinstance):
        # Before copying related objects from the old instance, the ones
        # on the current one need to be deleted. Otherwise, duplicates may
        # appear on the public version of the page
        self.associated_item.all().delete()

        for associated_item in oldinstance.associated_item.all():
            # instance.pk = None; instance.pk.save() is the slightly odd but
            # standard Django way of copying a saved model instance
            associated_item.pk = None
            associated_item.plugin = self
            associated_item.save()


class AssociatedItem(models.Model):
    plugin = models.ForeignKey(
        ArticlePluginModel,
        related_name="associated_item"
    )
