Answer 1

First include the jquery validation file in your layout. Then in rails form add class to validation required fields as <%= f.text_field :firstname, :class => "required" %>. Then write a method with form_id to trigger the validation. That is you have to give like

$(document).ready(function () { 
   $("your_form_id").validate();  
});
