在 Woocommerce Rest API 上使用 Rails 5 创建订单问题

Question

我有一个 rails 5 网络应用程序正在尝试 post 使用 woo commerce api 将订单返回到 wordpress 网站。

我使用的 gem 包装器是：

gem "woocommerce_api"

如果我对一个订单项进行硬编码，我可以完美地创建订单。但是我不知道如何添加多个订单项。请参阅下面的第一个 "working example"，然后查看下面我尝试遍历订单项的尝试。

我收到的错误响应是：

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

显然我不应该在请求中放置一个 .each 循环...但我不知道任何其他方式？

正在工作POST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"
    }
  ]
}

多个订单项请求失败

@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: [
      @cart_items.each 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
  ],
  shipping_lines: [
    {
      method_id: "flat_rate",
      method_title: "Flat Rate",
      total: "0"
    }
  ]
}

Answer 1

我认为问题与 each 方法的使用有关。

The most important thing to remember about the each method is that it does not change the return value. It implicitly returns the original array.

改为查看 map 或 collect 方法，其中 "creates a new array containing the values returned by the block".

...
  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，在数据负载中使用方法并不好读，因此我建议您将其重构为一个变量：

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

或进入 Cart 模型中的实例方法。
