The Rails Guides
A bit of an ongoing read since The Guides are a collection of walk-throughs, references, and informationals, but the content itself is great. Earlier this year I became frustrated at my having been a ‘rails developer’ for a couple of years but still not fully grasping the (somewhat hand-wavy) ‘Rails Way’. While I’d been told much earlier on to read the Rails Guides, I never did - though I’d mention that a great deal of The Guides will be better understood once you have some legitimate time spent developing in Rails for the sake of context. Having now read most of The Guides, they’ve been just fantastic. It can be a bit dry as far as reading goes, but these guides will explain the ‘Rails Way’ and have made me feel way more comfortable and skilled since. Don’t sleep on the Rails Doctrine either.
