ruby-on-rails – 更新Stripe的客户信用卡信息

我终于想出了如何使用这个 tutorial实现Stripes Monthly Billing.

到目前为止,用户可以创建&使用Stripe删除其订阅.但我无法调用API中的哈希值以让用户更改其信用卡信息.

问题：如何调用/传递文档中的子参数以使用我创建的update_card方法更新信用卡字段？

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

楷模

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 = "myteam@gmail.com"
    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

这是Stripe的文档示例响应

#<Stripe::Customer id=cus_3OWtLd5pirU4te 0x00000a> JSON: {
  "object": "customer","created": 1390946171,"id": "cus_3OWtLd5pirU4te","livemode": false,"description": "Customer for test@example.com","email": null,"delinquent": false,"Metadata": {
  },"subscription": null,"discount": null,"account_balance": 0,"currency": "usd",###I need to be able to update the data inside the customers card
  "cards": {
    "object": "list","count": 1,"url": "/v1/customers/cus_3OWtLd5pirU4te/cards","data": [

      }
    ]
  },"default_card": "card_103OWt2eZvkylo2CgyXLaqcd"
}

参考：Stripe Documentation for Ruby

js.coffee

jQuery ->
  Stripe.setPublishableKey($('Meta[name="stripe-key"]').attr('content'))
  subscription.setupForm()

subscription =
  setupForm: ->
    $('#new_subscription').submit ->
      $('input[type=submit]').attr('disabled',true)
      if $('#card_number').length
        subscription.processCard()
        false
      else
        true

  processCard: ->
    card =
      {number: $('#card_number').val(),cvc: $('#card_code').val(),expMonth: $('#card_month').val(),expYear: $('#card_year').val()}

    Stripe.createtoken(card,subscription.handleStripeResponse)

  handleStripeResponse: (status,response) ->
    if status == 200
      $('#subscription_stripe_card_token').val(response.id)
      $('#new_subscription')[0].submit()
    else
      $('#stripe_error').text(response.error.message)
      $('input[type=submit]').attr('disabled',false)

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

解决方法

您可以创建一张新卡并删除旧卡,该卡将为该客户制作新卡default_card,或者您也可以通过更新客户并传递此处提到的卡详细信息(检查卡字段及其子参数)来实现它.

编辑：

像这样做

require "stripe"
Stripe.api_key = "sk_test_BQokikJOvBiI2HlWgH4olfQ2"

token = Stripe::Token.create(
   :card => {
   :number => "4242424242424242",:cvc => "314"
   },)
cu = Stripe::Customer.retrieve("cus_3Ok02kebTNsPDJ")
cu.card = token.id
cu.save
