Question

我是Spreecommerce的新手，我在创建具有自定义属性的产品时遇到问题＆＃39; delivery_on＆＃39;通过管理界面。简而言之，我创建了migrate，product_decorator.rb，将新属性添加到允许的属性，为管理页面创建一个deface文件。但是，我收到一条错误消息，说明＆＃34;交货时无法生效＆＃34;当我尝试通过管理界面创建新产品时。

非常感谢您的任何帮助！

我使用ruby 2.2.1，rails 4.2.3和以下狂欢宝石：

gem 'spree_core',             branch: '3-0-stable'
gem 'spree_api',              branch: '3-0-stable'
gem 'spree_backend',          branch: '3-0-stable'
gem 'spree_gateway',          github: 'spree/spree_gateway', branch: '3-0-stable'
gem 'devise'

重现的步骤

创建迁移rails g migration add_delivery_on_to_spree_products

在迁移文件YYYYMMDDHHMMSS_add_delivery_on_to_spree_products中，插入更改以更改＆＃39;方法：

def change
  add_column :spree_products, :delivery_on, :date
  add_index :spree_products, :delivery_on
end

运行bundle exec rake db:migrate并将属性添加到spree_products表中，但它不会更新scheema.rb
运行rake db:migrate:reset并更新架构。但它首先消灭了数据库。不确定这是理想的做法（遵循stackoverflow thread上的指导）

在app / models / spree文件夹中，创建＆＃39; product_decorator.rb＆＃39;文件并添加

Spree::Product.class_eval do
  validates :delivery_on, presence: true
  delegate_belongs_to :master, :delivery_on, :active
end

在app / controllers / application_controllers.rb中，添加

Spree::PermittedAttributes.product_attributes << :delivery_on
Spree::Api::ApiHelpers.product_attributes << :delivery_on

在app / overrides / spree中，创建deface文件＆＃39; add_delivery_on_to_product_new＆＃39;：

Deface::Override.new(:virtual_path => 'spree/admin/products/new',
  :name => 'add_delivery_on_to_product_new',
  :original => '931806c52c232e6a373cb06fa739f3913ad13c3d',
  :insert_after => "erb[loud]:contains('text_field :available_on')",
  :text => "
    <%= f.field_container :delivery_on, class: ['form-group'] do %>
      <%= f.label :delivery_on, raw(Spree.t(:delivery_on) + content_tag(:span, ' *')) %>
      <%= f.error_message_on :delivery_on %>
      <%= f.text_field :delivery_on, :class => 'datepicker form-control' %>
    <% end %>
  ")

在app / overrides / spree中，创建deface文件＆＃39; add_delivery_on_to_product_form＆＃39;：

Deface::Override.new(:virtual_path => 'spree/admin/products/_form',
  :name => 'add_delivery_on_to_product_edit',
  :original => '931806c52c232e6a373cb06fa739f3913ad13c3d',
  :insert_after => "erb[loud]:contains('text_field :available_on')",
  :text => "
    <%= f.field_container :delivery_on, class: ['form-group'] do %>
      <%= f.label :delivery_on, raw(Spree.t(:delivery_on) + content_tag(:span, ' *')) %>
      <%= f.error_message_on :delivery_on %>
      <%= f.text_field :delivery_on, :value =>
datepicker_field_value(@product.delivery_on), class: 'datepicker form-control' %>
    <% end %>
  ")

Answer 1

我删除了

delegate_belongs_to :product, :delivery_on

来自我的product_decorator.rb文件，解决了这个问题。

说实话，我并没有真正理解delegate_belongs_to的作用，但我添加了它，因为官方Spree deface overrides tutorial指示我们这样做：

我们还需要将sale_price委托给主变体以便   获取更新的产品编辑表单。

我们可以通过创建新文件来完成此操作   app / models / spree / product_decorator.rb并添加以下内容   它：

模块Spree Product.class_eval做       delegate_belongs_to：master，：sale_price end end

注意，我尝试过delegate_belongs_to：master，：delivery_on，但也没有。
