Simple handling for phone numbers in rails apps. Make the aggressive assumption that a valid phone number is a 10 digit number. Users can input numbers in any format so long as they contain exactly 10 numeric digits.

Phone numbers will be stripped of all non-numberic characters before being saved, so your database contains just normalized numbers.

Valid numbers include "1231231234", "123-123-1234", and "(123) 123 1234".

Add this line to your application's Gemfile:

gem 'rails_phone'

Or install it yourself as:

$ gem install rails_phone

Add has_phone_number:

class Person
  has_phone_number
end

This will assume an attribute :phone exists. If you'd like to set it up on a custom set of attributes just pass them in:

class Person
  has_phone_number :cell, :mobile
end

Uses a test rails app:

cd test/dummy
rake db:migrate
rake db:test:prepare

rake test  (from project dir)
