Tim and santosh: you should put the
require ‘validates_uri_existence_of’
at the very begin or at the very end of your config/environment.rb, i.e. not inside the Rails::Initializer block

Hi Ilya,
Thanks for this - it’s super.
I’m having a problem. It works on my local machine, but when i deploy to my server i get the following error. I have included the validates_uri_existence_of.rb and the edit to the environment.rb.
Your help is greatly appreciated.

Tim

Santosh, extracting urls from a piece of text is a completely different problem. To tackle that, you should probably look at Hpricot wiki for examples of finding all the “a” elements in the DOM, and getting their “href” attributes.

Santosh, it sounds like you’re missing the activerecord/rails gems. Are you running a rails application?
