Question

For example,

User adds this “iamsmelly.com”.

And if I add an href to this, the link would be

http://www.mywebsite.com/iamsmelly.com

Is there a way to make it absolute if its not prepended by an http:// ?

Or should I revert to jQuery for this?

Probably a good place to handle this is in a before_save on your model. I’m not aware of a predefined helper (though auto_link comes somewhat close) but a relatively simple regexp should do the job:

class User < ActiveRecord::Base
   before_save :check_links
   def check_links
     self.link = "http://" + self.link unless self.link.match /^(https?|ftp):\/\//
   end
end
