问题
Like others working with Stripe payments, I was getting an error 'Cannot charge a customer that has no active card'. The form was not appending the token because the javascript did not have a matching id in the form, but now I am getting an rails error and the card is not being charged, the customer is created, the error states that there is an invalid line item, when the code to create the customer and charge the card is not run the order is created without error.

Working Order Form below, you cannot pass fields to Stripe and use them in the rails form to save in the db, its either or (previous example attempted to save address fields in the db and pass them to stripe as part of the transaction validation.
<%= form_for(@order, :html => {:id => 'payment-form'}) do |f| %>
<% if @order.errors.any? %>
<div id="error_explanation">

The form required the id referenced inthe javascript below
var stripeResponseHandler = function(status, response) {
var $form = $('#payment-form');
if (response.error) {
// Show the errors on the form
$form.find('.payment-errors').text(response.error.message);
$form.find('button').prop('disabled', false);
} else {
// token contains id, last4, and card type
var token = response.id;
// Insert the token into the form so it gets submitted to the server
$form.append($('<input type="hidden" name="stripeToken" />').val(token));
// and re-submit
$form.get(0).submit();
}
};
jQuery(function($) {
$('#payment-form').submit(function(e) {
var $form = $(this);
// Disable the submit button to prevent repeated clicks
$form.find('button').prop('disabled', true);
Stripe.card.createToken($form, stripeResponseHandler);
// Prevent the form from submitting with the default action
return false;
});
});
