我正在使用Ruby on Rails 4和Spree，我必须使用外部支付服务 - liqpay - https://www.liqpay.com/，因此我创建了自定义网关，自定义Checkout控制器和用于liqpay回调的Created控制器。付款完成后，我有预先最后一页和一个“完成订单”的按钮，一切似乎都很好。但是当我点击这个但是我有一个错误时，这就是日志中的内容

完成付款后调用的控制器方法看起来非常简单
def payment_network_callback
if @order.paid?
@order.next
end
redirect_to checkout_state_path(@order.state)
end
和Api控制器方法是（看起来像黑客，但我不知道该怎么做）
def liqpay_api_callback
@order = Spree::Order.find params[:order_id]
@order.payments.create! source: Spree::LiqpayCheckout.create, amount: @order.total,
payment_method: Spree::PaymentMethod.where(type: 'Spree::Gateway::Liqpay').first if @order.payments.length == 0
if params[:status] == 'success' || params[:status] == 'sandbox'
@order.update_attribute :payment_state, 'paid'
head :ok
else
head :unprocessable_entity
end
rescue => e
logger.fatal e.class.to_s
logger.fatal e.to_s
logger.fatal e.backtrace.join('/n')
head :internal_server_error
end
那么，你有什么想法，'未知属性：服务器'是什么以及如何正确地做到这一点？谢谢！
答案 0 :(得分：2)
找到解决方案。可能它不是好风格，但它有效。所以，主要的逻辑是在CheckoutController装饰器中的回调方法，它在liqpay付款完成后被调用
def payment_network_callback
if @order.paid?
@order.payments.first.process!
@order.deliver_order_confirmation_email
@order.next
@order.finalize!
session[:order_id] = nil
end
redirect_to "/orders/#{@order.number}"
end
还有另一种方法 - 我的应用程序API方法，liqpay在paiment更改它在另一个控制器中的状态后调用它
def liqpay_api_callback
@order = Spree::Order.find params[:order_id]
sign = get_callback_sign(params[:amount], params[:order_id], params[:status], params[:transaction_id], params[:sender_phone])
@order.payments.create! source: Spree::LiqpayCheckout.create, amount: @order.total,
payment_method: Spree::PaymentMethod.where(type: 'Spree::Gateway::Liqpay').first if @order.payments.length == 0
sign[-1]=''
if (params[:status] == 'success' || params[:status] == 'sandbox') && (sign.eql? params[:signature])
@order.update_attribute :payment_state, 'paid'
head :ok
else
head :unprocessable_entity
end
rescue => e
logger.fatal e.class.to_s
logger.fatal e.to_s
logger.fatal e.backtrace.join('/n')
head :internal_server_error
end
end
这就是Gateway的样子
module Spree
class Gateway::Liqpay < Gateway
attr_accessor :server, :test_mode
preference :server,:string, default: 'test'
preference :test_mode, :boolean, default: true
def provider
@provider = self
end
def purchase(amount, source, options = {})
Class.new do
def success?; true; end
def authorization; nil; end
end.new
end
def auto_capture?
true
end
def payment_profiles_supported?
true
end
def provider_class
self.class
end
def method_type
'liqpay'
end
end
end
