Comment (by Simon Charette):
Note that another elegant solution to this problem could be to add support
to transforms to `ForeignObject.to_fields` and `.from_fields` so you could
do something along these lines
{{{#!python
class Animal(models.Model):
name = models.TextField()
tags = generic.GenericRelation(Tag, from_field='id__text')
}}}
(assuming we'd register a `__text` lookup for `IntegerField`)
