When I run this:

rails generate controller hello index

it no doubt generates hello controller, but accidentally when I run another command like this:

rails generate controller world

it creates the world controller successfully, but missed the Route "world/index" like as "hello/index". For this mistake I need to use destroy controller and then generate it once more, is thr some kind of mid way command that I can generate if forgotten something rather than destroying and creating every time.

This command

rails generate controller contact-us index

creates a route as contact_us/index or contact_us after changing routes.rb under config folder. How could I create a more SEO friendly URL in RoR? Like localhost:3000/contact-us?

I am working on some very basic rules to follow RoR..like 3 static pages (Home, About us, Contact Us) Just simple html content to understand more, will certainly add more features to it as well.

localhost:3000/home
localhost:3000/About_us
localhost:3000/contact_us

I created this via creating home, About_us, contact_us controller command and then changed html in views. Since I am on an initial phase, I read somewhere for static pages we can create this in our public like what we have error pages there in the folder or the approach im using is correct?
