Copy tags to copied django object

I'm using django-taggit to tag my to do records. 

class Action(models.Model):
    name = models.CharField("Action Name", max_length=200)
    complete = models.BooleanField(default=False, verbose_name="Complete?")

    tags = TaggableManager()

I'm trying to make an exact copy of a records, down to the tags that are associated with the task.

new_obj = deepcopy(self)
new_obj.id = None
new_obj.save()

After running this code, the copy is exact except that there are no affiliated tags. How can I copy all of the tags from "self" to new_obj?

Solution

  • Instead of adding the tags to the object:

    new_obj.tags.add(tag)

    I added the new object to the Tag:

    for tag in self.tags.all():
    tag_object = TaggedItem(content_object = new_obj, tag = tag)
    tag_object.save()
