from query_view.models import make_typed_tag_tagged_model

class TaggedThing(TaggedItemBase):
    content_object = models.ForeignKey('Thing', on_delete=models.CASCADE)


class Thing(models.Model):
    name = models.CharField(max_length=200)
    is_good = models.BooleanField()

    tags = TaggableManager(through=TaggedThing, blank=True)

    def __str__(self):
        return self.name

# Subclass TypedTag
class ActorTypedTag(TypedTag):
    pass

# Create your tagged model like this
ActorTaggedThing = make_typed_tag_tagged_model('ActorTaggedThing', ActorTypedTag, Thing, app_label='testproject')

# Or like this
class ActorTaggedThing(TaggedItemBase):
    typed_tag = models.ForeignKey(
        ActorTypedTag,
        related_name="%(app_label)s_%(class)s_items",
        on_delete=models.CASCADE,
    )
