I love using ActiveRecord Migrations to build tables. Sometimes, I don''t want to use autogenerated PK''s - I want to set them automatically (why? I''m importing read only data from a large list of medications, and want to use the PK''s assigned by the medication research company...). Is there anyway to do this using Migrations?

I cannot seem to find any reference to labels in realtime extensions - using 1.4. I've googled until my eyes have bled, and also scoured voip-info.org. Is there anything that helps me here ? Many thanks. Julian

Hi all - I''d like to implement a lookup table in my app that contains some reference data, just some status codes and their descriptions. What''s the most appropriate approach according to the "rails way" of doing things? Would I just implement a has_many relationship?

Frankly I''m losing tolerance for the MS "stack." And I''m intrigued by Rails. But in my outfit I''m not only the web person, but also the application person and the DBA. So when I read that Rails doesn''t want to handle things like "compound keys" I blew right by those claims, thinking, "no way." But before I go deeper, I
