Parse URLs in comments into links

Question

I am building my own blog in Rails. One thing I would like to do is convert urls in comments into actual links.

I am not sure how to do this without opening up the page to injection.

Is there a library/plugin (or technique I am not thinking of) that does this?

apparently there's a gem to do that in Rails 3.1+ rails_autolink

If it's Rails 3.0 and down, then use the auto_link helper that is explained here : Convert plain text URLs to HTML hyperlinks in Ruby on Rails?

Thanks, I am using 3.2 I will check this out. – JD Isaacks Aug 04 '12 at 02:17
Awesome, I can even pass a hash with attributes to set on the links like: `auto_link text, :html => {:rel => 'no follow', :target => '_blank'}` – JD Isaacks Aug 04 '12 at 02:29
