Story

I started a new job where I need to get up to speed with RoR. I've dabbled with it a decade ago, and understand the scaffolding/generators/etc but still feel very out of place on actual fundamentals.

I have been doing lots of iOS, Python, React/Angular and Node.js/Express work for the last 10+ years so I am not looking for "how to learn to program" type books, more so understanding the patterns of Ruby/Rails.
