Rails Tutorial is probably the single most influential training course among the Rails community -- at least anecdotally.

I have worked with dozens of Rails devs over the years and in my estimation at least 80% have done the Rails Tutorial. In my opinion, it's the single best resource for learning Rails in a way consistent with real-world best practices.
