I have a situation where I have some legacy tables that have what I will call conditional relations. One table is a log and has actions and action_notes columns if the action is a certain number(value) the the contents of the action_notes will be a foreign key to another table but then it can actually be a note for other actions.... Hope that makes sense. So whats the best rails approach?
Unless those log tables are still being written to, I'd typically just write a migration to actually sort out the mess into a more standard layout and then work from there.
Oh, and LART the daylights outta whoever thought *that* design was a
good idea.
