I am trying to learn RoR and have a couple of misconceptions I’d like to clear up for myself. 1. One of the great things that are touted in every demo of RoR is the ability to add a new column to a table and it automagically appears on the web page. While this is nice and all, this doesn’t happen auto magically. It means that on every web request, the RoR framework must query the schema somehow. That’s convenient but it’ll bring a well trafficked site to its knees. Does this only happen in the Dev mode? 2. All tutorials and examples use MySQL as the database. How does one access MSSQL or Sybase? Is there a standardized access technique? Regards ---
