Hello Core :-) If Davids intentions with single layer of cleverness is possible to achieve (http://www.loudthinking.com/arc/000516.html), why did then CDBaby.com need to change to PostgreSQL to be able to get control of their data integrity, forced foreign keys and constraints? Was this before Rails? (Ref. http://www.oreillynet.com/ruby/blog/2005/11/migrating_to_ruby_on_rails_and.html) Question for Jeremy Kemper: Is CDBaby using Rails with a single layer of cleverness or do they still use the features of PostgreSQL RDBMS. If CDBaby uses both functionallity from RDBMS and Rails model. How do you handle this? Do you maintain both the database and Rails-models or do you only configure one of the places? Does Rails really work with a single layer of cleverness on large/complex database applications or is it only intended on simpler applications? /MartOn --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
