Marks invalid fields of semantic form, according to validation errors, received from server in JSON format.

Installation¶ ↑

Simply add FormtasticAjaxValidation to your Gemfile and bundle it up:

gem 'formtastic_ajax_validation'

Require javascripts assets:

= require formtastic_ajax_validation

Require stylesheets assets:

= require formtastic_ajax_validation

Having semantic form, like this:

= semantic_form_for User.new, :remote => true do |f|
  = f.inputs do
    = f.input :name
    = f.input :email

Bind validation to it via CoffeeScript:

FormtasticAjaxValidation $("#new_user"), "user", ["name", "email"]

Where “user” is a name of a model, and [“name”, “email”] are names of fields, that should reflect validation state.
