Quite a journey! I’m curious to see how well Foodsoft might run on a raspberry pi.
It seems like your rails server is listening on localhost only, which means you can’t reach it from anywhere else than your pi. You might try running
rails s -b 0.0.0.0
Regarding the directory, you may use anything you like. The way you’re running it here uses Thin, a Ruby-based webserver, which you can run from anywhere.
This is great to develop Foodsoft, or to just try it out. When you’d start using it for real, it’s recommended to use the production envirnoment and a front-facing webserver (*).
Hope this helps to get you going.
