How to duplicate inline objects to live?

Question

I am new to Django CMS. I created a plugin with inlines. When I save the plugin and when I publish the page the model gets duplicated but the inline objects are not getting duplicated.

Is there any way to do this? I want my inline objects also to save in live objects when I publish the page.

You need to implement a copy_relations method on your plugin. The documentation is here, but essentially the functionality works like this;

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"
    )
