Ruby on rails Stripe and Rails 5-Stripe:：InvalidRequestError:没有这样的计划：starter

我几乎看完了Ryan Bigg的《Rails多租户-第二版》一书，发现自己在将应用程序与Stripe集成时陷入了困境。特别是，我遇到了这个问题：

测试失败如下所示：

Failures:

     Failure/Error: subscription = customer.subscriptions.create(plan: "starter")

  end

  def chosen
    customer = Stripe::Customer.retrieve(current_account.stripe_customer_id)
    plan = Plan.find(params[:account][:plan_id])
    subscription = customer.subscriptions.create(
      plan: plan.stripe_id,
      source: params[:token]
    )

    current_account.plan = plan
    current_account.stripe_subscription_id = subscription.id
    current_account.stripe_subscription_status = "active"
    current_account.save
    flash[:notice] = "Your account has been created."
    redirect_to root_url(subdomain: current_account.subdomain)
  end

  def cancel
    customer = Stripe::Customer.retrieve(current_account.stripe_customer_id)
    subscription = customer.subscriptions.retrieve(current_account.stripe_subscription_id).delete
    if subscription.status == "canceled"
      current_account.update_column(:stripe_subscription_id, nil)
      flash[:notice] = "Your subscription to Twist has been cancelled."
      redirect_to root_url(subdomain: nil)
    end
  end
end

除了测试规范失败之外，当我访问subdomain.lvh.me:3000并经历注册用户+输入测试cc信息的过程时，条带过程似乎在一定程度上正常工作，但我被重定向到以下错误：

Stripe::InvalidRequestError in Accounts::PlansController#chosen
Received unknown parameter: source

customer = Stripe::Customer.retrieve(current_account.stripe_customer_id)
plan = Plan.find(params[:account][:plan_id])
subscription = customer.subscriptions.create(
  plan: plan.stripe_id,
  source: params[:token]
)

我的Plans Controller代码如下所示：

    t.index ["subdomain"], name: "index_accounts_on_subdomain", using: :btree
  end

条带计划获取程序

class StripePlanFetcher
  def self.store_locally
    Stripe::Plan.all.each do |plan|
      if local_plan = Plan.find_by(stripe_id: plan.id)
        local_plan.update(
          name: plan.nickname,
          amount: plan.amount
        )
      else
        Plan.create(
          name: plan.nickname,
          amount: plan.amount,
          stripe_id: plan.id
        )
      end
    end
  end
end

问题在于，您试图创建一个具有属性的订阅，但“计划”不是订阅的属性，而是对计划记录的引用。最有可能的是订阅有一个名为

plan\u id

的属性（在将来发布所有模式-在这种情况下，了解订阅的模式会很有帮助）

因此，在这种情况下，您可能需要声明

plan

是什么样的：

@plan=plan.find_by（name:'starter'）

---

customer.subscriptions.create（plan:@plan）

您也可以发布模型的模式吗？问题是您正在使用属性

plan='starter'

创建订阅。我猜

starter

类似于

plan.id

或

plan.name

。它应该是这样的：

customer.subscriptions.create（plan\u id:1）

@gwalshington刚刚发布在上面。感谢您的帮助/想法。我不确定这是否会改变您的答案/想法，但我设置它的方式是，我在stripe中创建了计划，并使用stripe\u plan\u fetcher.rb检索我在stripe中创建的计划。其中一个计划名为“启动者”（不过这是一个昵称）。不过，上面更新“starter”中的条带计划获取程序代码不是

id

。这是

名称

。查看并可能应该将

计划

作为

项目

列表传递
