Validation Error Notifier

Validation error notifier helps you uncover user experience issues quickly in your Ruby on Rails forms. The gem detects and notifies you when a form submission fails because of an invalid model. Strict model validation keeps your data clean, but it introduces friction in your forms. Keep your users happy by reducing that friction.

The gem currently only supports email notifications. It is useful at the beginning of a project to uncover major ux issues in your forms, but as your app get some traction you might want to track your full funnel in another tool that scales better.

Add the gem to your project's Gemfile:

gem 'validation_error_notifier'

Install the gem

bundle install

Configure the email notifier in an initializer:

config/initializers/validation_error_notifier.rb

ValidationErrorNotifier::EmailNotifier.configure do |c|
  c.default_sender = "notifier@example.com"
  c.default_recipients = "recipient@example.com"
  c.default_subject_prefix = "[MYAPP]"
end

Enable the validation error notifier using the notify_validation_errors method in your controllers. You can enable the notifier for all actions in all your controllers:

class ApplicationController < ActionController::Base
  notify_validation_errors
end

The method accepts the same options as a Rails after filter, you can constraint the actions for which the notifier is enabled using :only and :except :

class PostsController < ApplicationController
  notify_validation_errors :only => [:create]
end

Only an email notifier has been implemented, but other notifiers could easily be plugged in (eg, statsd). Pull requests for new notifiers are welcome.

Part of this gem was inspired by the Guardrail notifier. If you want a proper commercial service to do this check out their service: Guardrail

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
