Validates As Email

Ximon Eighteen <ximon> Dan Kubb <dan> Thijs van der Vossen <thijs>

This Ruby on Rails plugin implements an ActiveRecord validation helper called validates_as_email. The helper acts as if validates_format_of was used with a regular expression that defines an RFC822 email address conformance test.

The plugin implements the regular expression here:

http://tfletcher.com/lib/rfc822.rb

Which is an implementation in Ruby of a regular expression published by Cal Henderson for PHP here:

http://www.iamcal.com/publish/articles/php/parsing_email

Installation:

ruby script/plugin install https://svn.greenpeace.org/repositories/rails_plugins/validates_as_email

Full documentation on script/plugin can be obtained by invoking the plugin script with no arguments:

You may need to restart your webserver in order to load the plugin files.

Usage:

class MyClass < ActiveRecord::Base validates_presence_of :email validates_as_email :email end

Tests:

Some tests have been added.
