Mascherari

An easy way to handle masks. (Work in progress)

Installation

Simple as:

$ gem install mascherari

Usage

To create masks for attributes, include Mascherari and set the format:

class Person
  include Mascherari

  attr_accessor :phone

  attr_masked :phone, :format => "(##) ####-####"
end

That will give you two helpers to use along with the object:

# person.phone = "5554212035"
person.phone_masked
=> "(55) 5421-2035"

# person.phone = "(55) 5421-2035"
person.phone_unmasked
=> "5554212035"

You can set a format for more than one attribute:

attr_masked :phone, :mobile, :format => "(##) ####-####"

And also use a different wildcard, if needed:

attr_masked :phone, :format => "(**) ****-****", :wildcard => "*"

For the cases when format can vary, it's possible to set multiple formats:

attr_masked :phone, :format => ["(##) ####-####", "(###) ####-####"]

Rails

Add this line to your application's Gemfile:

gem 'mascherari'

And then execute:

$ bundle

You can include Mascherari in Rails models as:

# config/initializers/mascherari.rb
ActiveSupport.on_load :active_record do
  include Mascherari
end

# app/models/person.rb
class Person < ActiveRecord::Base
  attr_masked :phone, :format => "(##) ####-####"
end
