Question

我有一个Rails 5网络应用程序，它正在尝试使用 woo commerce api 将订单发布回wordpress网站。

我正在使用的宝石包装纸是：

gem "woocommerce_api"

如果我对一个订单项进行硬编码，则可以完美地创建订单。但是，我不知道如何添加多个订单项。请参见下面的第一个“有效示例”，然后请参见下文尝试遍历订单项的内容。

我得到的错误响应是：

{"code"=>"woocommerce_rest_required_product_reference", "message"=>"Product ID or SKU is required.", "data"=>{"status"=>400}}

很明显，我不应该在请求中添加.each循环...但是我不知道其他方式吗？

工作后请求

@cart_items = Cart.where(user_id: @user.id).all

data = {
  status: "processing", 
  currency: "AUD",
  set_paid: true,
  billing: {
    first_name: "#{@user.first_name}",
    last_name: "#{@user.last_name}",
    address_1: "#{@user.address}",
    address_2: "",
    city: "#{@user.suburb}",
    state: "#{@user.state}",
    postcode: "#{@user.postcode}",
    country: "Australia",
    email: "#{@user.email}",
    phone: "#{@user.phone}"
  },
  shipping: {
    first_name: "#{@user.first_name}",
    last_name: "#{@user.last_name}",
    address_1: "#{@user.address}",
    address_2: "",
    city: "#{@user.suburb}",
    state: "#{@user.state}",
    postcode: "#{@user.postcode}",
    country: "Australia",
  },
  line_items: [
      {
        :product_id => 123,
        :variation_id => 1,
        :quantity => 2
        :subtotal => "10.00",
        :total => "20.00"
      }
  ],
  shipping_lines: [
    {
      method_id: "flat_rate",
      method_title: "Flat Rate",
      total: "0"
    }
  ]
}

失败的多行项目请求

data = {
  status: "processing", 
  currency: "AUD",
  set_paid: true,
  billing: {

  line_items: [

      {
        :product_id => ci.product.woo_id.to_i,
        :variation_id => 0,
        :subtotal => ci.product.price.to_s,
        :total => ((ci.product.price.to_d * ci.quantity.to_i).round(2)).to_s
      }
    end
  ],
  shipping_lines: [

    }
  ]
}

我相信问题与使用each方法有关。

关于each方法要记住的最重要的事情是它不会更改返回值。它隐式返回原始数组。

请改为查看map或collect方法，该方法“创建一个包含该块返回的值的新数组”。

...
  line_items: @cart_items.map do |ci|
    {
      :product_id => ci.product.woo_id.to_i,
      :variation_id => 0,
      :subtotal => ci.product.price.to_s,
      :total => ((ci.product.price.to_d * ci.quantity.to_i).round(2)).to_s
    }
  end,
...

但是，正如您所说的那样，在数据有效载荷中使用方法并不便于阅读，因此我建议您将其重构为变量：

@line_items = ...map function here...
data: {
...
  line_items: @line_items
...

或进入Cart模型中的实例方法。
