Stripe創建兩個訂閱

Question

我剛剛使用Stripe轉換功能模型以創建charge以創建subscription，出於某種原因，現在它創建了兩個訂閱而不是一個訂閱。我new查看代碼，因爲它的工作並沒有改變，所以問題不在這裏（在我看來），但由於this SO post曾與JS一個問題，我想反正表露出來：

<%= form_tag charges_path do %> 
    <article> 
    <% if flash[:error].present? %> 
     <div id="error_explanation"> 
     <p><%= flash[:error] %></p> 
     </div> 
    <% end %> 
    <label class="amount"> 
     <span>Amount: $7.99/month</span> 
    </label> 
    </article> 

    <script src="https://checkout.stripe.com/checkout.js" class="stripe-button" 
      data-key="<%= Rails.configuration.stripe[:publishable_key] %>" 
      data-description="Generator Subscription" 
      data-amount="799" 
      data-locale="auto"></script> 
<% end %> 

這裏是我的控制器，在那裏我相信這個問題必須位於：

class ChargesController < ApplicationController 
    def new 
    unless current_user 
     flash[:error] = "Step one is to create an account!" 
     redirect_to new_user_registration_path 
    end 

    if current_user.access_generator 
     flash[:notice] = "Silly rabbit, you already have access to the generator!" 
     redirect_to controller: 'generators', action: 'new' 
    end 
    end 

    def create 
    customer = Stripe::Customer.create(
     :email => params[:stripeEmail], 
     :source => params[:stripeToken], 
     :plan => "generator_access" 
    ) 

    subscription = Stripe::Subscription.create(
     :customer => customer.id, 
     :plan => "generator_access" 
    ) 

    if subscription 
     current_user.update_attributes(access_generator: true) 
     current_user.update_attributes(stripe_customer_id: subscription.customer) 
     current_user.update_attributes(stripe_sub_id_generator: subscription.id) 
     flash[:notice] = "You have been granted almighty powers of workout generation! Go forth and sweat!" 
     redirect_to controller: 'generators', action: 'new' 
    end 

    rescue Stripe::CardError => e 
    flash[:error] = e.message 
    redirect_to new_charge_path 
    end 

    def cancel_subscription 
    @user = current_user 
    customer = Stripe::Customer.retrieve(@user.stripe_customer_id) 
    subscription = Stripe::Subscription.retrieve(@user.stripe_sub_id_generator) 

    if customer.cancel_subscription(params[:customer_id]) 
     @user.update_attributes(stripe_customer_id: nil, access_generator: false, stripe_sub_id_generator: nil) 
     flash[:notice] = "Your subscription has been cancelled." 
     redirect_to user_path(@user) 
    else 
     flash[:error] = "There was an error canceling your subscription. Please notify us." 
     redirect_to user_path(@user) 
    end 
    end 

end 

的cancel_subscription方法效果很好（有一次我手動刪除通過條紋儀表盤複製訂閱），所以它真的有什麼東西在「創建」方法。我還檢查了我的控制檯，並且User屬性的信息正在正確更新，以匹配正在創建的兩個重複訂閱中的第二個。

任何人都可以看到爲什麼這段代碼產生兩個訂閱？

當您使用計劃創建客戶時，會自動創建相應的訂購。您不需要手動創建它。
