Rails: redirect to current path but different subdomain

Question

I think this should be fairly easy but I\'m not familiar with how it\'s done...

How do you write a before filter that would check if the current request is for certa

Answer 1

An even simpler option without the need to do a string sub or specify the controller or action would be to use

redirect_to url_for(subdomain: 'www', only_path: false)
