ValidatesCPF
Validates cpf and test it in a simple way. Depends on ruby >= 2.2. For older ruby versions use the version 2 series.
Installation
Add this line to your application's Gemfile:
gem 'validates_cpf'
And then execute:
$ bundle
Or install it yourself as:
$ gem install validates_cpf
Usage
Just use as any other validator:
class User < ActiveRecord::Base
  validates :cpf, cpf: true
end
To force the attribute to be masked pass option mask:
class User < ActiveRecord::Base
  validates :cpf, cpf: { mask: true }
end
Testing
Require the matcher:
require 'validates_cpf/require_a_valid_matcher'
Use in your tests:
it { is_expected.to require_a_valid_cpf } # It will test the attribute :cpf by default
it { is_expected.to require_a_valid_cpf(:id) }
