title: Validating JQuery autocomplete using client_side_validations in ruby on rails
body: <p>I jave job which belongs_to client. I want to validate presence of client_id in jobs/new form. I am using jQueryUI autocomplete for picking client and I use client_side_validations for validations. After selecting client, I have javascript code to set value to client_id, but it is hidden_field which is not included in client side validations. Is there any way to validate its presence without modifying rails.validations.js?</p>
