validates_email

validates_email is a Rails gem that validates email addresses against RFC 2822 and RFC 3696

Installation

Add the following to your gemfile

gem 'roomorama-validates_email', :require => 'validates_email'

Usage

class User < ActiveRecord::Base
  validates :primary_email, :email => true
end

As well as any other Rails validation this one has the same triggers, such as :on, :if, :unless, :allow_blank, and :allow_nil.

Also, you can pass your own custom error message.

class User < ActiveRecord::Base
  validates :primary_email, :email => { :message => 'is not an email address' }
end

If you like to check MX Records for email, you can use :mx option.

class User < ActiveRecord::Base
  validates :primary_email, :email => { :mx => true }
end

And if you like to check MX Records with fallback to A record, use :a_fallback option.

class User < ActiveRecord::Base
  validates :primary_email, :email => { :mx => { :a_fallback => true } }
end

I18n

If you don't specify your own error message, then ActiveRecord's :invalid error message will be used to show the error.

If do check MX Records, then you have to specify your own error message or add it to your traslations:

activerecord:
  errors:
    messages:
      mx_invalid: "is not valid"

Credits

Based off the spectagor-validates_email gem. Most of the code were taken from Alex Dunae (dunae.ca) plugin (see http://github.com/alexdunae/validates_email_format_of/) and adopted for Rails 3 playing around with Rails 3 beta, so pass all beers to him.
