# PhonyRails [![Build Status](https://travis-ci.org/joost/phony_rails.svg?branch=master)](https://travis-ci.org/joost/phony_rails) [![Coverage Status](https://coveralls.io/repos/joost/phony_rails/badge.svg)](https://coveralls.io/r/joost/phony_rails) ![Dependencies Status](https://img.shields.io/gemnasium/joost/phony_rails.svg) ![Gem](https://img.shields.io/gem/v/phony_rails.svg)

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).

Find version information in the [CHANGELOG](CHANGELOG.md).

## Installation

Add this line to your application's Gemfile:

```ruby
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:

```ruby
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
```

#### ActiveModel (models without database)

For Rails-like models without a database, add:

```ruby
class SomeModel
  include ActiveModel::Model # we get AR-like attributes and validations
  include ActiveModel::Validations::Callbacks # a dependency for normalization

  # your attributes must be defined, they are not inherited from a DB table
  attr_accessor :phone_number, :phone_number_as_normalized

  # Once the model is set up, we have the same things as with ActiveRecord
  phony_normalize :phone_number, default_country_code: 'US'
end
```

#### Mongoid

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

```ruby
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:

```ruby
# 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).

#### Default for all models

You can set the default_country_code for all models using:

```ruby
PhonyRails.default_country_code = "US"
```

### Validation

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

```ruby
validates :phone_number, phony_plausible: true
```
or the helper method:

```ruby
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:

```ruby
validates_plausible_phone :phone_number, presence: true
validates_plausible_phone :phone_number, with: /\A\+\d+/
validates_plausible_phone :phone_number, without: /\A\+\d+/
validates_plausible_phone :phone_number, presence: true, with: /\A\+\d+/
```

the i18n key is `:improbable_phone`. Languages supported by default: de, en, fr, it, ja, kh, nl, tr, ua and ru.

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

```ruby
validates_plausible_phone :phone_number, country_number: '61'
```

or correct country code:

```ruby
validates_plausible_phone :phone_number, country_code: 'AU'
```

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

```ruby
phony_normalize :phone_number, as: :phone_number_normalized, default_country_code: 'US'
validates_plausible_phone :phone_number, normalized_country_code: 'US'
```

Validation supports phone numbers with extension, such as `+18181231234 x1234` or `'+1 (818)151-5483 #4312'` out-of-the-box.

#### Allowing records country codes to not match phone number country codes

You may have a record specifying one country (via a `country_code` attribute) but using a phone number from another country.  For example, your record may be from Japan but have a phone number from the Philippines. By default, `phony_rails` will consider your record's `country_code` as part of the validation.  If that country doesn't match the country code in the phone number, validation will fail.

Additionally, `phony_normalize` will always add the records country code as the country number (eg. the user enters '+81xxx' for Japan and the records `country_code` is 'DE' then `phony_normalize` will change the number to '+4981'). You can turn this off by adding `enforce_record_country: false` to the validation options. The country_code will then only be added if no country code is specified.

If you want to allow records from one country to have phone numbers from a different one, there are a couple of options you can use: `ignore_record_country_number` and `ignore_record_country_code`.  Use them like so:

```ruby
validates :phone_number, phony_plausible: { ignore_record_country_code: true, ignore_record_country_number: true }
```

Obviously, you don't have to use both, and you may not need or want to set either.

### Display / Views

In your views use:

```erb
<%= "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:

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

To return nil when a number is not valid:

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

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

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

You can also easily normalize a phone number String:

```ruby
"+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'
```

Extensions are supported (identified by "ext", "ex", "x", "xt", "#", or ":") and will show at the end of the number:

```ruby
"+31 (0)30 1234 123 x999".phony_normalized # => '31301234123 x999'
"+31 (0)30 1234 123 ext999".phony_normalized # => '31301234123 x999'
"+31 (0)30 1234 123 #999".phony_normalized # => '31301234123 x999'
```


### 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.

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