ValidatesIdentity

This projects aims to validate several countries person identification documents. It works on top of 2 attributes, so that the identity can be determined by a second value and thus validate the first one accordingly

Add this line to your application's Gemfile:

gem 'validates_identity'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install validates_identity

Just require the plugins you want/need in your Gemfile and you will be good to go

• Argentina DNI
• Brazil CPF
• Brazil CNPJ
• Chile RUT
• Colombia CC
• Colombia NIT
• Guatemala DPI
• Panama RUC
• Peru DNI
• Peru RUC
• Mexico RFC

Just use as any other validator:

class User < ActiveRecord::Base
  # :identity_type is the attribute that will be used to determine the identity type and is required
  validates :identity, identity: { identity_type: :identity_type }
end

The format option can be used to format the final identity value.

class User < ActiveRecord::Base
  # all values will be formatted after successful validation
  validates :identity, identity: { identity_type: :identity_type, format: true }
end

The only option can be used to narrow down the validators

class User < ActiveRecord::Base
  # will accept only person identity types
  validates :identity, identity: { identity_type: :identity_type, only: :person }
  # will accept only legal identity types
  validates :identity, identity: { identity_type: :identity_type, only: :legal }
  validates :identity, identity: { only: 'MX_RFC_PERSON' }
end

One of the options that only accept is :person. This will tell the validator to only accept individual type documents and reject legal type documents

class User < ActiveRecord::Base
  # will accept only person identity types
  validates :identity, identity: { identity_type: :identity_type, only: :person }
end

One of the options that only accept is :legal. This will tell the validator to only accept legal type documents and reject individual type documents

class User < ActiveRecord::Base
  # will accept only legal identity types
  validates :identity, identity: { identity_type: :identity_type, only: :legal }
end

Another option that only accept is a unique document registration key. This will tell the validtor to only accept this document type and reject any other one

class User < ActiveRecord::Base
  # will accept only Argentina DNI
  validates :identity, identity: { only: 'AR_DNI' }
end

Note that when using this scenarion it is not necessary neither accepted to define the secondary column through identity_type.

In case of a legacy system where keys were already defined and differ from the official ones, aliases can be registered to easy the transition

ValidatesIdentity.register_person_identity_type_alias('LegacyIdentity', 'CustomIdentity')
ValidatesIdentity.register_legal_identity_type_alias('LegacyIdentity', 'CustomIdentity')

New Identity Validators can be registered through the public apis of ValidatesIdentity

ValidatesIdentity.register_person_identity_type('CustomIdentity', CustomIdentityValidator)
ValidatesIdentity.register_legal_identity_type('CustomIdentity', CustomIdentityValidator)

A Validator must implement:

• a constructor with 1 param: value
• a valid? method that returns a boolean
• a formatted method that returns the formatted value

When adding a new validator, cases of success and error can be added through and API so that the Matcher will test against them

ValidatesIdentity::ShouldaMatchers.register_allowed_values('CustomIdentity', ['123456789', '123.456.789'])
ValidatesIdentity::ShouldaMatchers.register_disallowed_values('CustomIdentity', ['12345679', '12.456.789'])

Require matcher in your spec_helper or rails_helper file:

require 'shoulda/matchers/active_model/require_a_valid_identity_matcher'

Use in your tests:

it { is_expected.to require_a_valid_identity } # It will test the attributes :identity and :identity_type by default
it { is_expected.to require_a_valid_identity(:id, :my_type) }

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
