I am trying to do a Rails + AJAX call validation to check for the
uniqueness of a field, by crawling the back end DB and return an
appropriate message based on the result.
I am on Rails 3.0.11.
Your kind inputs on what could be the best way to tackle this would be
of real help.
Is there a ruby gem / js plugin / jquery plugin that I can make use of?
Any blogs links implementing the same would also be handy..
