 For example:


 {{{
 class Node(models.Model):
     content_type = models.ForeignKey(ContentType,
 on_delete=models.CASCADE)
     object_id = models.PositiveIntegerField()
     content_object = GenericForeignKey("content_type", "object_id")

 class AbstractNodeItem(models.Model):
     name = models.CharField(max_length=100)

 class ItemA(AbstractNodeItem):
     a_content = models.TextField()

 class ItemB(AbstractNodeItem):
     b_content = models.TextField()

 }}}

 Currently we can't list all  node with only `content_object.name`
 prefetched.
