Stripe_ruby Unable to store card_last4 and card_type after successful customer creation

Stripe_ruby Unable to store card_last4 and card_type after successful
customer creation

After creating a customer successfully, I can inspect the object with:
Rails.logger.debug("single card object has:
#{customer.cards.data.card.inspect}")
which returns a json like this:
#<Stripe: : Customer: 0x2801284>JSON: {
"id": "cus_2WXxmvhBJgSmNY",
"object": "customer",
"cards": {
"object": "list",
"data": [
{
"id": "card_2WXxcCsdY0Jjav",
"object": "card",
"last4": "4242",
"type": "Visa",
"exp_month": 1,
"exp_year": 2014,
}
]
},
"default_card": "card_2WXxcCsdY0Jjav"
}
But I will do Customer.cards.data.last4 it gives a NOMethodError.
If I remove the last4 and just call Customer.cards.data, it gives
#<Stripe: : Card: 0x1ed7dc0>JSON: {
"id": "card_2Wmd80yQ76XZKH",
"object": "card",
"last4": "4242",
"type": "Visa",
"exp_month": 1,
"exp_year": 2015,
}
Now I seem to have the direct card object but if I do
card = Customer.cards.data
self.last4 = card.last4
I still get a noMethodError
Here is shortened version of my model:
class Payment < ActiveRecord::Base
def create_customer_in_stripe(params)
if self.user.stripe_card_token.blank?
user_email = self.user.email
customer = Stripe::Customer.create(email: user_email, card:
params[:token])
card = customer.cards.data
self.card_last4 = card.last4
self.card_type = card.type
self.card_exp_month = card.exp_month
self.card_exp_year = card.exp_year
self.user.save
end
self.save!
end
end
