Ruby on rails 如何定制Spree签出过程？

我的环境

Mac OSX 10.7.4
Ruby 1.9.3p0
Rails 3.2.3
Spree 1.1.0

你好，我是日本程序员和菜鸟狂欢。我想定制Spree的结帐流程，以删除结帐步骤，例如选择交货方式和付款方式

根据，我需要为

Order

模型定义一个全新的状态机

因此，我将

order\u decorator.rb

添加到

app/models

目录中，如下所示

# app/models/order_decorator.rb

module SpreeCustomExtension
  class Engine < Rails::Engine
    def self.activate
      Order.class_eval do
        Order.state_machines[:state] = StateMachine::Machine.new(Order, :initial => 'cart') do
          after_transition :to => 'complete', :do => :complete_order
          before_transition :to => 'complete', :do => :process_payment

          event :next do
            transition :from => 'cart', :to => 'payment'
            transition :from => 'payment', :to => 'confirm'
            transition :from => 'confirm', :to => 'complete'
          end

          event :cancel do
            transition :to => 'canceled', :if => :allow_cancel?
          end
          event :return do
            transition :to => 'returned', :from => 'awaiting_return'
          end
          event :resume do
            transition :to => 'resumed', :from => 'canceled', :if => :allow_resume?
          end
          event :authorize_return do
            transition :to => 'awaiting_return'
          end

          before_transition :to => 'complete' do |order|
            begin
              order.process_payments!
            rescue Spree::GatewayError
              if Spree::Config[:allow_checkout_on_gateway_error]
                true
              else
                false
              end
            end
          end

          after_transition :to => 'complete', :do => :finalize!
          after_transition :to => 'confirm', :do => :create_tax_charge!
          after_transition :to => 'payment', :do => :create_shipment!
          after_transition :to => 'canceled', :do => :after_cancel

        end
      end
    end
  end
end

但是，似乎没有任何变化。有人知道我应该在哪里修改以定制结账流程吗

请建议一些好的狂欢教程或建议。我真的很感激你的建议

提前感谢。

您需要位于Spree命名空间中，覆盖Spree:：Order，而不仅仅是Order

我认为你的订单装饰师应该看起来有点不同。 只需创建一个文件

app/models/spree/order\u decorator.rb

然后像这样开始

Spree::Order.class_eval do
  state_machine do
    before_transition to: "address" do |order|
    ...
  end
end

谢谢你的评论，我将在Spree的名称空间中尝试。非常感谢。

Spree::Order.class_eval do
  state_machine do
    before_transition to: "address" do |order|
    ...
  end
end
