Answer 2

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();  
}); 

Answer 3

You can use the jquery validation rails gem based on jquery validation plugin. To use it

1. Add the gem to your gemfile gem 'jquery-validation-rails'

2. On your app/assets/javascripts/application.js add the following lines

   //= require jquery.validate.additional-methods //= require jquery.validate

3. As of turbolinks 5 which is included in rails 5 instead of using $(document).ready use $(document).on "turbolinks:load" as described in turbolinks readme
