【问题描述】：

我正在尝试向 spree 管理页面添加一项功能以重新发送发货电子邮件。

我收到了这个错误，

ActionView::Template::Error (undefined method `resend_shipment_email_admin_order_url' for #<#<Class:0x0000000668cf80>:0x00000006683700>):
    16:               </ul>
    17:             
    18:   <%= button_link_to Spree.t('Resend order email'), resend_admin_order_url(@order), method: :post, icon: 'email' %>
    19:   <%= button_link_to Spree.t('Resend shipment email'), resend_shipment_email_admin_order_url(@order), method: :post, icon: 'email'
 %>
    20:   </div>
    21:           <% end %>
    22:         </div>

这是我的装饰器，app/controllers/spree/orders_controller_decorator.rb，

Spree::Admin::OrdersController.class_eval do

  before_action :load_order, only: [:edit, :update, :cancel, :resume, :approve, :resend, :resend_shipment_email, :open_adjustments, :close_adjustments, :cart]

  def resend_shipment_email
    if @order.shipment_state == "shipped"
      ShipmentMailer.shipped_email(@order.shipments.last.id).deliver
      flash[:success] = "Shipment Email Resent"
      redirect_to :back
    else
      flash[:error] = "Cannot send shipment email. Order not marked as shipped."
      redirect_to :back
    end
  end

end

这是我的路线，

  namespace :admin do
    resources :orders, except: [:show] do
      member do
        post :resend_shipment_email
      end
    end
  end

这是视图覆盖，

Deface::Override.new(:virtual_path => 'spree/admin/shared/_content_header',
  :name => 'add_resend_shipment_email_button_to_spree_admin',
  :insert_bottom => "[data-hook='toolbar'], #toolbar[data-hook]",
  :text => "
  <%= button_link_to Spree.t('Resend order email'), resend_admin_order_url(@order), method: :post, icon: 'email' %>
  <%= button_link_to Spree.t('Resend shipment email'), resend_shipment_email_admin_order_url(@order), method: :post, icon: 'email' %>
  "
)

这是一个来自 rake 路由的 sn-p，

resend_shipment_email_admin_order POST   /admin/orders/:id/resend_shipment_email(.:format) admin/orders#resend_shipment_email
                               resend_admin_order POST     /admin/orders/:id/resend(.:format)                                          spree/admin/orders#resend

【解决方案1】：

我必须做的是修复我的路线文件，以便 spree 可以识别，

Spree::Core::Engine.routes.draw do
    namespace :admin do
      resources :orders, except: [:show] do
        member do
          post :resend_shipment_email
        end
      end
    end
  end
