checkout - spree 结账 - 删除步骤

Question

我正在尝试删除 2 个结帐步骤。
我试图遵循站点中的文档http://guides.spreecommerce.com/checkout.html
但仍然没有任何 react 。

我在用
spree 1.1.2
ruby 1.9.2p318
导轨 3.2.6
Ubuntu 12.04(精确)32 位

我会告诉你我做了什么，你会告诉我要修复什么。
我应该更改文件的名称或位置吗？
还是我也应该更改其他文件？
我该如何调试它？

我创建了一个新文件“app/models/spree/order_decorator.rb”(也在“app/models/order_decorator.rb”下尝试过)

module SpreeCustomExtension

  class Engine < Rails::Engine

    def self.activate

      Spree::Order.class_eval do



        StateMachine::Machine.ignore_method_conflicts = true   # I HAVE ADDED THOSE 2 LINES LATER, HOPING IT WOULD HELP ME,

        Spree::Order.state_machines.clear                                # IT DIDN'T.



        # customize the checkout state machine

        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 => '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 Core::GatewayError

              !!Spree::Config[:allow_checkout_on_gateway_error]

            end

          end



          before_transition :to => ['delivery'] do |order|

            order.shipments.each { |s| s.destroy unless s.shipping_method.available_to_order?(order) }

          end



          after_transition :to => 'complete', :do => :finalize!

          after_transition :to => 'delivery', :do => :create_tax_charge!

          after_transition :to => 'payment',  :do => :create_shipment!

          after_transition :to => 'resumed',  :do => :after_resume

          after_transition :to => 'canceled', :do => :after_cancel 

        end



      end

    end

  end

end

然后我用不同的代码尝试了同一个文件，仍然没有发生任何事情

Spree::Order.class_eval do 



  StateMachine::Machine.ignore_method_conflicts = true 

  Spree::Order.state_machines.clear 



  state_machine :initial => 'cart', :use_transactions => false do 



    event :next do 

      transition :from => 'cart',     :to => 'payment', :if => :payment_required? 

      transition :from => 'cart',     :to => 'complete' 

      transition :from => 'confirm',  :to => 'complete' 



      # note: some payment methods will not support a confirm step 

      transition :from => 'payment',  :to => 'confirm', 

                                      :if => Proc.new { |order| order.payment_method && order.payment_method.payment_profiles_supported? } 



      transition :from => 'payment', :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 Core::GatewayError 

        if Spree::Config[:allow_checkout_on_gateway_error] 

          true 

        else 

          false 

        end 

      end 

    end 



    before_transition :to => ['delivery'] do |order| 

      order.shipments.each { |s| s.destroy unless s.shipping_method.available_to_order?(order) } 

    end 



    after_transition :to => 'complete', :do => :finalize! 

    after_transition :to => 'delivery', :do => :create_tax_charge! 

    after_transition :to => 'payment',  :do => :create_shipment! 

    after_transition :to => 'resumed',  :do => :after_resume 

    after_transition :to => 'canceled', :do => :after_cancel 



  end 



end 

Answer 1

好吧，我终于找到了——
Spree 发布了一个新版本 #1.2.0，对这个确切的问题进行了重大修复。

Spree 1.2.0 Release Notes

The checkout process has always been hard to customize within Spree, and that has generated complaints in the past. We are pleased to report in the 1.2 release of Spree that this has been substaintially easier...

所以现在的解决方案很简单 -
只需撤消您之前所有的结账操作尝试，
通过更新您的 gem 文件和捆绑安装将 spree 升级到 1.2.0，
按照他们的文档处理所有代码分解(我猜你会有一些)。
并在 app/models/spree/下创建一个简单的 order_decorator.rb

Spree::Order.class_eval do
  checkout_flow do
    go_to_state :address
    go_to_state :payment, :if => lambda { |order| order.payment_required? }
    go_to_state :confirm, :if => lambda { |order| order.confirmation_required? }
    go_to_state :complete
  end

  # If true, causes the payment step to happen during the checkout process
  def payment_required?
    return false
  end

  # If true, causes the confirmation step to happen during the checkout process
  def confirmation_required?
    return true
  end

end

请享用。
