You can't rely on industry to teach you what you need to know. They'll put you on endless treadmills learning hackneyed DSLs fueled by hype cycles. Fact is, Rails is almost entirely composed of patterns from PoEAA, along with DHH's excellent taste. At some point, you need to read and apply those patterns yourself to really understand them.

Actually, now that I think about it, you're almost much better off self-teaching once you get to a certain competency level.
