validate_credit_card_fields

Simple gem helpful in validating standard credit card forms. Consists of validation for credit card, its cvv, expiration date and owner. Also allows provider limitation.

Installation

Add this line to your application's Gemfile:

gem 'validate_credit_card_fields'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validate_credit_card_fields

Usage

Inside your model:

validate_credit_card_fields number: :your_cc_number_field,
                            cvv: :your_ccv_field,
                            month: :your_cc_month_field,
                            year: :your_cc_year_field,
                            owner: :your_cc_owner_field,
                            providers: [:amex, :visa]

In place of :your_something_field place keys representing desired value in your model.

providers are used to specify provider limitations. Supply it with a list of supported providers (those you want to be valid). Leaving it blank will allow any of the accepted providers below:

:visa, :master_card, :maestro, :diners_club, :amex, :discover, :jcb, :solo, :china_union, :dankort

When a field name isn't presented, validator will use default values:

:cc_number, :cc_cvv, :cc_month, :cc_year, :cc_owner

Now possible to validate credit card owner using first and last names, for example:

validate_credit_card_fields first_name: :your_first_name_field,
                            last_name: :your_last_name_field

If both :first_name and :last_name keys are provided, those two fields will be validated, otherwise it'll fall back to :owner.
