To learn Rails, I’ve started working on integrating it with a production system. Getting connected to SQL Server 2005 was a bit tricky – this guide helped move things along. Getting the ODBC connection string correct was a pain.
Everything I’ve seen so far on learning Rails focuses on building new apps. Its not clear to me how to integrate rails into an existing production system. The first problem is how to handle migrations? If I skip a migration because the table exists, what is the impact of not having the Rails-created fields id, created_at, updated_at in the table?
