This one by Evil Martians is fairly recent https://rails-tutorial.evilmartians.io/
I haven't done it, since I already know Rails very well, but I know these guys as reputable contributors to the Ruby ecosystem.
It’s the official new Getting Started but ported to a browser-based runtime powered by WebContainers, so you can complete the whole tutorial without having to install Ruby or Rails. It’s very cool!
