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)
