PhonyRails

This small Gem adds useful methods to your Rails app to validate, display and save phone numbers. It uses the super awesome Phony gem (https://github.com/floere/phony).

Installation

Add this line to your application's Gemfile:

gem 'phony_rails' # Include phony_rails after mongoid (if you use mongoid, see issue #66 on github).

And then execute:

$ bundle

Or install it yourself as:

$ gem install phony_rails

Usage

Normalization / Model Usage

ActiveRecord

For ActiveRecord, in your model add:

class SomeModel < ActiveRecord::Base
  # Normalizes the attribute itself before validation
  phony_normalize :phone_number, :default_country_code => 'US'

  # Normalizes attribute before validation and saves into other attribute
  phony_normalize :phone_number, :as => :phone_number_normalized_version, :default_country_code => 'US'

  # Creates method normalized_fax_number that returns the normalized version of fax_number
  phony_normalized_method :fax_number
end

Mongoid

For Mongoid, in keeping with Mongoid plug-in conventions you must include the Mongoid::Phony module:

class SomeModel
  include Mongoid::Document
  include Mongoid::Phony

  # methods are same as ActiveRecord usage
end

General info

The :default_country_code options is used to specify a country_code when normalizing.

PhonyRails will also check your model for a country_code method to use when normalizing the number. So '070-12341234' with country_code 'NL' will get normalized to '317012341234'.

You can also do-it-yourself and call:

# Options:
#   :country_code => The country code we should use (forced).
#   :default_country_code => Some fallback code (eg. 'NL') that can be used as default (comes from phony_normalize_numbers method).

PhonyRails.normalize_number('some number', :country_code => 'NL')

PhonyRails.normalize_number('+4790909090', :country_code => 'SE') # => '464790909090' (forced to +46)
PhonyRails.normalize_number('+4790909090', :default_country_code => 'SE') # => '4790909090' (still +47 so not changed)

The country_code should always be a ISO 3166-1 alpha-2 (http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2).

Validation

In your model use the Phony.plausible method to validate an attribute:

validates :phone_number, :phony_plausible => true

or the helper method:

validates_plausible_phone :phone_number

this method use other validators under the hood to provide:

  • presence validation using ActiveModel::Validations::PresenceValidator
  • format validation using ActiveModel::Validations::FormatValidator

so we can use:

validates_plausible_phone :phone_number, :presence => true
validates_plausible_phone :phone_number, :with => /^\+\d+/
validates_plausible_phone :phone_number, :without => /^\+\d+/
validates_plausible_phone :phone_number, :presence => true, :with => /^\+\d+/

the i18n key is :improbable_phone

You can also validate if a number has the correct country number:

validates_plausible_phone :phone_number, :country_number => '61'

or correct country code:

validates_plausible_phone :phone_number, :country_code => 'AU'

You can validate against the normalized input as opposed to the raw input:

phony_normalize :phone_number, as: :phone_number_normalized, :default_country_code => 'US'
validates_plausible_phone :phone_number, :normalized_country_code => 'US'

Display / Views

In your views use:

<%= "311012341234".phony_formatted(:format => :international, :spaces => '-') %>
<%= "+31-10-12341234".phony_formatted(:format => :international, :spaces => '-') %>
<%= "+31(0)1012341234".phony_formatted(:format => :international, :spaces => '-') %>

To first normalize the String to a certain country use:

<%= "010-12341234".phony_formatted(:normalize => :NL, :format => :international, :spaces => '-') %>

To return nil when a number is not valid:

"123".phony_formatted(:strict => true) # => nil

You can also use the bang method (phony_formatted!):

number = "010-12341234"
number.phony_formatted!(:normalize => :NL, :format => :international)
number # => "+31 10 123 41234"

You can also easily normalize a phone number String:

"+31 (0)30 1234 123".phony_normalized # => '31301234123'
"(0)30 1234 123".phony_normalized # => '301234123'
"(0)30 1234 123".phony_normalized(country_code: 'NL') # => '301234123'

Find by normalized number

Say you want to find a record by a phone number. Best is to normalize user input and compare to an attribute stored in the db.

Home.find_by_normalized_phone_number(PhonyRails.normalize_number(params[:phone_number]))

Changelog

0.8.2

  • Added String#phony_normalized method

TODO

  • Make this work: Home.find_by_normalized_phone_number(Home.normalize_number(params[:phone_number])) So we use Home.normalize_number instead of PhonyRails.normalize_number. This way we can use the same default_country_code.
  • Make country_code method configurable.
