Can I remove the default root in a Rails application without creating a new one?
If you want to render a 404 response, there are two approaches that I can think of.
Firstly, you could route to Rack, and return a simple 404 response:
# config/routes.rbroot to: proc { [404, {}, ["Not found."]] }Secondly, you could take the obvious route and point root to a controller action that returns 404:
# config/routes.rbroot to: "application#not_found"# app/controllers/application_controller.rbdef not_found render plain: "Not found.", status: 404endThe third option is, of course, to route to a non-existing action, but I don't think this is a good idea, since the intention is obscured, and could easily be taken for a mistake.
If you remove it, you will see the default greeting from Rails, which includes some technical information about your environment. Unlikely this is the behavior you need.
I solved it this way:
Rails.application.routes.draw do namespace :admin do ... end # To prevent users from seeing the default welcome message "Welcome aboard" from Rails root to: redirect('admin/sign_in')end
