This gem adds a very simple email address format validator to be used with ActiveRecord models in Rails 3.0+. It supports localized error messages.


Add the gem to your project’s Gemfile:

ruby gem 'email_validation'


This gem is an EachValidator, and thus is used with the validates method:

ruby class User < ActiveRecord::Base validates :email_address, presence: true, email: true end

The localization key is invalid_email, and can be specified in the localized YAML file like so:

yaml en: activerecord: errors: messages: invalid_email: Email address is invalid.
