email_validation

Simple email validator for Rails 3+

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:

gem "email_validation"

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

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:

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