On an "attitude" level, it's very useful to understand the doctrine of Ruby on Rails (RoR), as written by DHH [1]. Especially if you're coming from some other paradigms / languages etc., RoR can feel quite different. Understanding the philosophy is a nice window to kickstart the "way" of RoR.

On a more practical level, I've found the official Ruby on Rails guides [2] to be super helpful. I started a RoR job almost a year ago without having done any Ruby at all (I had a Python background). I probably should have gone through the tutorials in the OP and in other comments (rails tutorial book comes to mind). But since I didn't, I used the RoR guides A LOT. And they were super useful. Everything from routes, to controllers, to ActiveModel and migrations. They give you a good starting point to get most of the job done. Highly recommend looking at the relevant guides if you are working on specific RoR things!
