>Let Rails have its Id column and create an old_id, or legacy_id, or >customer_id, or whatever...and map it up. :) Yes, I agree. Just treat the old key as an attribute of your new rails model. You can use 'validates_uniqueness_of' to keep the old legacy key unique. Rails follows convention over configuration. You can venture 'off the rails', but you will have to carry more of the load yourself. Letting rails do what it wants to do will probably work out as a simpler solution for you in the long run.
