I think it would be very helpful if you guys used a plugin to show the keys / shortcuts you are using! Otherwise, I have to pause and go search it myself, which isn’t a big deal, but it slows down the process going through the video. I know you guys have videos on vim, which I’m also going through.
Also, I was wondering how you would implement a constraint in the routes on your own outside of a gem used for authentication? I agree that using before_action isn’t as pretty as using a constraint in the routes.
You guys have great articles over here rails - Giant Robots Smashing Into Other Giant Robots. I think linking to articles you guys have created that cover these topics more in depth would be helpful to the user if they want to learn more through the resources you guys have already created.
