Live validator is a Rails Guilded (http://github.com/midas/guilded/tree/master) component that will reflect ActiveRecord validations and use them to live validate forms. Live validator uses the Live Validation (http://www.livevalidation.com) JavaScript library to accomplish this task. It also uses an ActiveRecord extension authored by Michael Schuerig to mre easily reflect on the ActiveRecord valdiations.
