Module: SpreeStripe::CreditCardDecorator

Defined in:
app/models/spree_stripe/credit_card_decorator.rb

Overview

Backports Stripe's credit-card fingerprint dedup onto Spree::CreditCard for spree < 5.6.0, which doesn't ship it. spree >= 5.6.0 provides the column, scope, and validation in core, so this is only prepended (below) when core lacks it. (Wallet metadata accessors already live in core since 5.4, so they don't need backporting here.)
