Ruby 如何在 Shopify 脚本编辑器中显示数组值

随着假期的临近，我的团队正在为我们的Shopifystore 开发一个脚本，以防止我们的客户在购物车中出现以下情况之一时使用折扣代码:捐赠、已经打折的商品以及符合F30 335i赠品资格的商品.以下是我目前拥有的代码:

##disable discount codes##
error_message = 'Cannot use Discount. Reason(s) : '
marzano_donation_id = 6723597598805
marzano_donation = false
Input.cart.line_items.each do |line_item|
product = line_item.variant.product
puts product.id
if Input.cart.discount_code != nil 
    # only runs if customer has discount code
  if product.id == marzano_donation_id
    # marzano_donation = true
    marzano_error = "Marzano's Donation in cart, "
    error_message.concat(marzano_error)
        # Input.cart.discount_code.reject({message: "1"})
        
end
end
end



list_of_invalid_vendors = []
vendor_message = "Invalid vendors in cart : #{list_of_invalid_vendors}"
contains_vendor = false

vendor_list = ["Evolution Racewerks", "Kies Giveaway Items", "Precision Raceworks"]
Input.cart.line_items.each do |line_item|
vendor = line_item.variant.product.vendor
if vendor_list.include? vendor

    list_of_invalid_vendors.append(vendor)
    if Input.cart.discount_code != nil
      error_message.concat(vendor_message)
      puts list_of_invalid_vendors
      puts vendor_message
    end

  puts list_of_invalid_vendors
end


end
puts contains_vendor



contains_giveaway = false
Input.cart.line_items.each do |line_item|
product = line_item.variant.product
next unless product.tags.include?('Kies Giveaway Items')
# Input.cart.discount_code.reject({message: "3"})
    # contains_giveaway = true
    giveaway_error = " Cannot use discount code on Kies Giveaway Items, "
    error_message.concat(giveaway_error)
end
puts contains_giveaway
puts "123"


if Input.cart.discount_code != nil
Input.cart.discount_code.reject({message: "#{error_message}"})
end 


Output.cart = Input.cart

目前，使用此输出，我可以获得我想要的错误消息--但仅当它是字符串时.

我拼图的最后一块需要能够显示客户购物车中的无效供应商，如下所示:

list_of_invalid_vendors = []
vendor_message = "Invalid vendors in cart : #{list_of_invalid_vendors}"
contains_vendor = false

vendor_list = ["Evolution Racewerks", "Kies Giveaway Items", "Precision Raceworks"]
Input.cart.line_items.each do |line_item|
vendor = line_item.variant.product.vendor
if vendor_list.include? vendor

    list_of_invalid_vendors.append(vendor)
    if Input.cart.discount_code != nil
      error_message.concat(vendor_message)
      puts list_of_invalid_vendors
      puts vendor_message
    end

  puts list_of_invalid_vendors
end


end

我想要的是输出的代码:"不能在购物车中使用折扣，无效的供应商:演进赛车，精密赛车"

但相反，我一直得到的是:

不能使用折扣.原因:购物车中的供应商无效:[]
