【问题描述】:
我正在学习如何使用 Payola 为我的 RoR 5.1.5 测试应用创建订阅。我按照 wiki 上的说明进行操作。
我已经设置了从 Wiki 上的示例中获取的示例表单,并将其直接放入 app/views/subscriptions/new.html.erb。当我输入信用卡、电子邮件、到期日期并单击提交时,我收到此 Rails 错误:undefined method `amount' for nil:NilClass
我已经在 rails 控制台中创建了 SubscriptionPlan 并确认它存在。 我已确认在控制台中创建新计划后,它会显示在我的 Stripe 仪表板中。
我确定我忽略了一些东西,希望有人遇到过同样的问题并能指出我正确的方向。感觉就像我没有在任何地方指定计划。我不知道该怎么做。
感谢您的帮助。
代码在这里。 app/models/subscription_plan.rb
class SubscriptionPlan < ActiveRecord::Base
include Payola::Plan
end
/app/controllers/subscriptions_controller.rb
class SubscriptionsController < ApplicationController
# bring in the `render_payola_status` helper.
include Payola::StatusBehavior
def new
@plan = SubscriptionPlan.first
end
def create
# do any required setup here, including finding or creating the owner object
owner = current_user # this is just an example for Devise
# set your plan in the params hash
params[:plan] = SubscriptionPlan.find_by(id: params[:plan_id])
# call Payola::CreateSubscription
subscription = Payola::CreateSubscription.call(params, owner)
# Render the status json that Payola's javascript expects
render_payola_status(subscription)
end
end
/app/views/subscriptions/new.html.erb
<!-- this header can go in <head> or at the bottom of <body> -->
<%= render 'payola/transactions/stripe_header' %>
<%= form_tag('/subscriptions',
class: 'payola-onestep-subscription-form',
'data-payola-base-path' => '/payola',
'data-payola-plan-type' => @plan.plan_class,
'data-payola-plan-id' => @plan.id
) do |f| %>

堆栈跟踪/调用者堆栈会很有帮助。在不知道错误发生在哪里的情况下,我们无能为力。
