Given the following, where a Product can be associated with multiple Images via
a GFK:
# models:
class Image(models.Model):
image = ImageField(...)
class ImageAssociation(models.Model):
image = models.ForeignKey(Image, related_name='associations')
content_object = GenericForeignKey()
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField(db_index=True)
class Product(models.Model):
title = models.CharField(max_length=255)
images = GenericRelation('images.ImageAssociation',
related_query_name='products')
How would I go about adding/changing/deleting Products when editing an Image in
the admin? I can easily add/change/delete `ImageAssociation` via admin inlines,
but I am looking to take it another level: add/change/delete related `Product`
instances.
I've looked at nesting inlines via
https://github.com/theatlantic/django-nested-admin, but it looks like the
relations are not set up in a way that works - or at least I cannot figure out
how to arrange things.
Is it possible to set up a custom inline with a `Product` modelform that
automatically creates/removes/updates `ImageAssociation` relational instances
as well?
