A quick rake task to identify possible Spree orders that contain invalid payments that might actually have been successfully processed

gistfile1.rb

# Rake task
desc 'Generate a list of potential orders with falsely flagged invalid payments'
task list_orders_with_complete_and_invalid_payments: :environment do
  Spree::Order.complete.where(legacy: false).each do |order|
    if order && order.has_mulitple_payments? && order.has_an_invalid_and_complete_payment?
      puts " -> Order #{order.number} has a potentially problematic payment"
    end
  end
end
    

# to add to order model

def has_mulitple_payments?
  payments.count > 1
end

def has_an_invalid_and_complete_payment?
  payment_states & %w(completed invalid) == payment_states.uniq
end
      
def payment_states
  payments.map(&:state)
end
