I finally figured out how to implement Stripes Monthly Billing using this tutorial.
So far, A User can Create & Delete their Subscription with Stripe. But I am having trouble calling the hashes inside the API to have the User change his credit card information.
Question: How do I call/pass the child parameters in the documentation to update the Credit Card Fields using the method I have created update_card
?
This is my Code with Comments:
CONTROLLER
class SubscriptionsController < ApplicationController
def update
@subscription = current_user.subscription
### I use the method update_card to update the customer's card
@subscription.update_card
if @subscription.update_card
redirect_to edit_subscription_path, :success => 'Updated Card.'
else
flash.alert = 'Unable to update card.'
render :edit
end
end
end
MODELS
class Subscription < ActiveRecord::Base
attr_accessible :plan_id, :user_id, :email, :stripe_customer_token, :last_4_digits,
:card_token, :card_name, :exp_month, :exp_year, :stripe_card_token
attr_accessor :stripe_card_token
belongs_to :plan
belongs_to :user
### How can this work with my edit form. Would I need to store each person's new card?
def token
token = Stripe::Token.create(
:card => {
:number => "4242424242424242",
:exp_month => 1,
:exp_year => 2015,
:cvc => "314"
},
)
end
def update_card
customer = Stripe::Customer.retrieve(stripe_customer_token)
customer.email = "[email protected]"
customer.description = "Unlimited"
customer.card = token.id
customer.save
rescue Stripe::StripeError => e
logger.error "Stripe Error: " + e.message
errors.add :base, "#{e.message}."
false
end
Here is Stripe's Documentation Example Response

Stripe Error: You passed an empty string for 'card'. We assume empty values
are an attempt to unset a parameter; however 'card' cannot be unset. You
should remove 'card' from your request or supply a non-empty value
either you can create a new card and delete the old one that will make the new card default_card for that customer or you can also achieve it by updating the customer and passing card details as mentioned here(check card field and its child parameters) https://stripe.com/docs/api#update_customer
Edit:
Do it like this
require "stripe"
Stripe.api_key = "sk_test_BQokikJOvBiI2HlWgH4olfQ2"
token = Stripe::Token.create(
:card => {
:number => "4242424242424242",
:exp_month => 1,
:exp_year => 2015,
:cvc => "314"
},
)
cu = Stripe::Customer.retrieve("cus_3Ok02kebTNsPDJ")
cu.card = token.id
cu.save
