How to display the current subdomain URL in a Rails view?

Question

Using Rails 4 and Devise. How could I, in devise/sessions/new.html.erb, display the full current URL, e.g. http://(request.subdomain).example.com, in the view?

For example in new.html.erb:

<p>Please bookmark http://yoursubdomain.example.com</p>

Answer 1

<p>Please bookmark <%= "http://" + request.subdomain + ".example.com" %></p>

Hope this helps.

Answer 2

Try like that:-

request.original_url

In view as:-

<%= request.original_url %>
