ruby on rails - URL replacement from submitted comment -

-

i displaying users website url in comments. works correctly on view page, wondering if can change how url displayed.

can display http://google.com website? or remove http, https , display google.com?

here current code:

<%= link_to comment.website, url_for(comment.website), target: '_blank' %>

if comment.website returns string as: "http://google.com" can use regex trim "//" using: 

comment.website.remove(/.*\/\//)

this crash if comment.website nil can use different syntax write same code

comment.website.try(:remove, /.*\/\//)

so: 

<%= link_to comment.website.try(:remove, /.*\/\//), url_for(comment.website), target: '_blank' %>

go , check http://rubular.com/r/ufmy2djohw play regex
