Ruby on Rails (Rails) is good at doing the manual work for you. With one line, Rails can create the model, controller and view files associated with your application. The downside of using rails generate or its shortcut rails g is that small mistakes like typos are amplified. If Rails is expecting user, and you mistakenly typed users it could cause functionality errors.
This cheat sheet will help to avoid those conflicts.
If you are comfortable working with Rails, Model–view–controller (MVC) architecture rails generate, this post is for you.

You could also add the 'scaffold' to the cheetsheet
This is a good idea! The chart has been updated to include scaffold!
excellent! thank you!
(This is worthy of a PR to the rails documentation itself!?)
This is information I cannot remove from my memory.
Nice work !
It's join table naming that always trips me up.
