如何自定義Spree結帳流程？

Question

我的環境。

Mac OSX 10.7.4
Ruby 1.9.3p0
Rails 3.2.3
Spree 1.1.0

您好，我是Spree的日本程序員和新手。 我想自定義Spree的結帳流程，以刪除結帳步驟，例如選擇送貨方式和付款方式。

根據Spree指南 ，我需要為Order模型定義一個全新的狀態機。

因此，我將order_decorator.rb添加到app/models目錄，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

另外，我將spree_site.rb文件添加到我的lib/目錄中。

# lib/spree_site.rb

module SpreeSite
  class Engine < Rails::Engine
    def self.activate
      Dir.glob(File.join(File.dirname(__FILE__), "../app/**/*_decorator*.rb")) do |c|
        Rails.configuration.cache_classes ? require(c) : load(c)
      end
    end

    def load_tasks
    end

    config.to_prepare &method(:activate).to_proc
  end
end

但是，似乎根本沒有變化。 有人知道我應該在哪里修改以自定義結帳流程嗎？

請提出一些不錯的狂歡教程或建議。 我真的很感謝任何建議。

先感謝您。

Answer 1

您需要在Spree命名空間中，覆蓋Spree :: Order而不是簡單地訂購。

Answer 2

我認為您的訂單裝飾器看起來應該有所不同。 只需制作一個文件app/models/spree/order_decorator.rb

然后像這樣開始

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