I've already solved this in my app. We are using DM with a legacy schema (still in use by another app, so cannot be modified too much) and all of the PK's are generated from a sequences table (it's just `name` and `id` columns).
I've just done this with a "before :create" hook in my models, and the logic is just: SELECT id FROM sequences WHERE name = sequence_name FOR UPDATE UPDATE sequences SET id = id + 1 WHERE name = sequence_name I can't help but feel I've reinvented the wheel given that this is such a common design pattern, so does anyone know of a plugin that handles Serial fields via a sequences table?
