I actually picked up the book last week. I'm only four chapters in, but it's the best intro material I've read so far, and I'm looking forward to getting through the middle of the book and creating the Depot application.
After the Depot app, I have a "real" application I want to try, but I'm still very new to Rails, and I keep hearing about the "greenfield" vs legacy thing. I have three specific features in mind; maybe you can tell me if they're do-able in Rails.
My legacy app uses a back-end DB2 database. So far, no problem. But the tables have composite primary keys. Most of the examples of Rails apps I see use surrogate auto-generated integer primary keys. Are composite primary keys possible using Rails?
This legacy app I have in mind also uses Stored Procedures. I haven't seen any examples of this in Rails, at least from what I've seen so far. Can I call DB2 Stored Procedures in Rails?
Finally, this legacy app displays a grid, similar to DomAPI's Listgrid. Is something like this possible in Rails?
Thanks for a great book!
