I was watching DHH's demo on ActionCable and something took my attention more than it should in my opinion.
One of the first things we do for every application is to generate a root action and then manually edit routes.rb:
1 - rails g controller welcome index
2 - change routes.rb from "get 'welcome/index'" to "root to: 'welcome#index'"
Maybe it would be a good idea to introduce some kind of flag in the generator to get this done automatically. It may be a tiny change but it makes a difference when you are demoing any Rails application from scratch.
Maybe something like:
rails g controller welcome index:root help
Which would generate some routes like:
root to: 'welcome#index'
If another root action already exists or if two actions are flagged as root actions the generator command would raise an error.
Is this something you have considered before?
