ruby-on-rails - 如果我有 Stripe 卡 token ，我该如何检索客户 ID？

Question

我的应用使用设计来创建新用户，并将其与 Stripe 集成。

当我创建一个新客户时，我会返回(作为响应)一个 token ，它是卡的 token 。有没有办法使用该 token 检索客户的 ID？

我有一个 related question这显示了我当前的实现。我提出这个问题是因为我现在明白问题是我在创建新客户期间没有检索/存储客户的 ID。

任何提示都是有值(value)的。谢谢。

我的 JS( CoffeeScript )

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

user =
  setupForm: ->
    $('#new_user').submit ->
      $('input[type=submit]').attr('disabled', true)
      if $('#card_number').length
        user.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, user.handleStripeResponse)

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

我不在 Controller 中做任何事情。我只在我的 user.rb 中使用它:

 after_create :create_a_customer

 def create_a_customer
    token = self.stripe_card_token
    customer = Stripe::Customer.create(
      :card => token,
      :plan => 1,
      :email => self.email
      )         
  end

我们的 JS 看起来是一样的，所以我想我会发布我的表单和 Controller 操作以及我的模型，它对用户进行一些处理和保存。如果有任何帮助，请告诉我!抱歉，我似乎找不到确切的错误，但我知道，对我来说，有一个工作示例来查看总是有帮助的!

表格--

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:class => 'form card_form' }) do |f| %>

  <%= f.email_field :email, :required => true, :class => "deviseFormInput", :placeholder => "EMAIL" %><br />
  <i>PASSWORD MINIMUM OF 6 CHARACTERS</i>
  <%= f.password_field :password, :required => true, :class => "deviseFormInput", :placeholder => "PASSWORD" %>
  <%= f.password_field :password_confirmation, :required => true, :class => "deviseFormInput", :placeholder => "PASSWORD CONFIRMATION" %>
  <div class="field">
    <%= f.input :meatless, as: :boolean, :class => "deviseFormInput", :label => "I AM A VEGETARIAN" %>
  </div>
  <%= f.input :comments, as: :text, :placeholder => "ALLERGIES OR INTOLERANCES", :label => false, input_html: { class: 'deviseFormInput', style: 'width: 280px; height: 100px;' } %>

  <% if @user.stripe_customer_token %>
    <p>Credit card acceptance is pending.</p>
  <% else %>
    <div class="field">
      <%= text_field_tag :card_number, nil, name: nil, :class => "deviseFormInput", :placeholder => "CREDIT CARD NUMBER" %>
    </div>
    <div class="field">
      <%= text_field_tag :card_code, nil, name: nil, :class => "deviseFormInput", :placeholder => "CARD SECURITY CODE (CVV)" %>
    </div>
    <div class="field">
      <%= label_tag :card_month, "CARD EXPIRATION" %>
      <br>
      <div class="presser presserDeep">
        <%= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"} %>
      </div>
      <div class="presser">
        <%= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+10}, {name: nil, id: "card_year"}%>
      </div>
    </div>
  <% end %>
  <%= f.hidden_field :stripe_card_token %>
  <%= f.button :submit, 'SIGN UP', :class => 'deviseBtn' %>

<% end %>

Controller --

def create
  shopping_cart_id = session[:shopping_cart_id]
  @shopping_cart = session[:shopping_cart_id] ? ShoppingCart.find(shopping_cart_id) : ShoppingCart.create
  session[:shopping_cart_id] = @shopping_cart.id
  @user = User.new(params[:user])
  if @user.save_with_payment
    sign_in @user
    redirect_to root_path, :notice => "Thank you for signing up!"
  else
    render :new
  end
end

MODEL(用于 save_with_payment 方法)--

def save_with_payment
  if valid?
    customer = Stripe::Customer.create(description: email, card: stripe_card_token)
    self.stripe_customer_token = customer.id
    self.last_4_digits = customer.cards.data.first["last4"]
    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
