Purpose

It validates email for application use (registering a new account for example)

Usage

In your Gemfile :

gem 'valid_email'

In your code :

require 'valid_email'
class Person
  include ActiveModel::Validations
  attr_accessor :name, :email

  validates :name, :presence => true, :length => { :maximum => 100 }
  validates :email, :presence => true, :email => true
end


p = Person.new
p.name = "hallelujah"
p.email = "john@doe.com"
p.valid? # => true

p.email = "john@doe"
p.valid? # => false

p.email = "John Does <john@doe.com>"
p.valid? # => false

You can check if email domain has MX record :

validates :email, :email => {:mx => true, :message => I18n.t('validations.errors.models.user.invalid_email')}

Or validates :email, :email => {:message => I18n.t('validations.errors.models.user.invalid_email')}, :mx => {:message => I18n.t('validations.errors.models.user.invalid_mx')}

If you don't want the MX validator stuff, just require the right file

require 'valid_email/email_validator'

Or in your Gemfile

gem 'valid_email', :require => 'valid_email/email_validator'

Note on Patches/Pull Requests

  • 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.
