Unable to charge customer using stripe - ruby-on-rails

Question

I'm trying to save a customer with credit card details and charge it later.
So far I was able to do the following:
Get the card token to Stripe (I see it in the logs in stripe and in my Rails console)
Create a customer, send it to Stripe and save the customer id in my database.
When I try to charge the customer I get the following error:
Stripe::CardError (Cannot charge a customer that has no active card)
Maybe the card token is not assigned to the customer properly? How can I solve it? maybe it's something simple that I'm missing but I've been trying to get a solution for a while.
application.rb:
class Application < ActiveRecord::Base
attr_accessor :stripe_card_token
def save_with_payment
if valid?
customer = Stripe::Customer.create(
description: id,
email: self.user.email,
source: self.stripe_card_token
)
self.stripe_customer_token = customer.id
save!
end
rescue Stripe::InvalidRequestError => e
logger.error "Stripe error while creating customer: #{e.message}"
errors.add :base, "There was a problem with your credit card."
false
end
applications.js.coffee:
jQuery ->
Stripe.setPublishableKey($('meta[name="stripe-key"]').attr('content'))
application.setupForm()
application =
setupForm: ->
$('#new_application').submit ->
$('input[type=submit]').attr('disabled', true)
if $('#card_number').length
application.processCard()
false
else
true
processCard: ->
card =
number: $('#card_number').val()
cvc: $('#card_code').val()
exp_month: $('#card_month').val()
exp_year: $('#card_year').val()
Stripe.createToken(card, application.handleStripeResponse)
handleStripeResponse: (status, response) ->
if status == 200
$('#application_stripe_card_token').val(response.id)
$('#new_application')[0].submit() ->
return true if($form.find('.application_stripe_card_token').val())
else
$('#stripe_error').text(response.error.message)
$('input[type=submit]').attr('disabled', false)

Your application_params() filter method doesn't appear to permit the stripe_card_token that gets submitted from your form. I believe that if you add that to your permit() filter list, you should be able to get the value through to the controller, so that it can be used when it's needed.
