ServerSideValidation

This is simple ruby gem(https://rubygems.org/gems/server_side_validation) to show model validation on view for each form field.

Add this line to your application's Gemfile:

gem 'server_side_validation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install server_side_validation

1. To show model validation next to the form field make sure you should have a js request from form.

2. use show_validation_errors method in controller action as

    if @object.save
        your code goes here ....
    else
        show_validation_errors(object)
    end

3. In html.erb files, you need to write 'error' class for displaying error message next to the form field.

Also define 'field_name_txt' class for each of the field present on form.

<%= contact.text_area :message, class: 'form-control message_txt' %>
<div class ='error'></div>

This will show an validation error message inline next to your form fields.
