I have fun blog posts about Ruby on Rails, a book about them and many other recommendations. Here’s a lot of my favourite material on that subject. Yes, especially if I wrote it :-)
Rails Basics and Rails Internals:
About Ruby on Rails Internals:
- A workshop I gave at Southeast Ruby 2019 - similar to, but quite different from, Rebuilding Rails; build a stripped-down minimal MVC framework as fast as possible, roughly
- My book, Rebuilding Rails, is about how to understand Ruby on Rails deeply by building your own Ruby web framework, from blank directories, structured like Rails.
