I understand models, views, and controllers from a design DRY perspective. How would I create a basic calculator in rails using best practices. Online there is way too much on scaffolding and tests that it just completely confuses the heck outa me. I dont know where to use what variables and how to decide where they go and all. I am a total noob. Please help.
For the basics, it’s very useful read the rails guides.
