ValidatesCPF

Validates cpf and test it in a simple way. Supports ruby 2.2+ and rails 3+. For older ruby versions use the version 2.

Add this line to your application's Gemfile:

gem 'validates_cpf'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validates_cpf

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

Require the matcher:

require 'validates_cpf/require_a_valid_cpf_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) }
