标签: ruby-on-rails csv rake shopify

我正在使用rake任务从一个csv获取数据,使用该数据调用shopify api,并将响应保存到另一个CSV。问题是我没有错误处理程序,所以如果shopify api找不到我提供的资源,整个任务就会中止。处理错误的最佳方法是什么,以便在Shopify中找不到资源时,只需跳过它并继续下一行?

以下代码中调用shopify API的行是:
variant = ShopifyAPI::Variant.find(vid)

namespace :replace do
    desc "replace variant id with variant sku"

    task :sku => :environment do
        file="db/master-list-3-28.csv"
        newFile = Rails.root.join('lib/assets', 'newFile.csv')
        CSV.open(newFile, "a+") do |csv|
            CSV.foreach(file) do |row|

                msku, namespace, key, valueType, value = row
                valueArray = value.split('|')
                newValueString = ""

                valueArray.each_with_index do |v, index|

                    recArray = v.split('*')
                    handle = recArray[0]
                    vid = recArray[1]
                    newValueString << handle
                    newValueString << "*"
                    # use api call to retrieve variant sku using handle and vid
                    #replace vid with sku and save to csv

                    variant = ShopifyAPI::Variant.find(vid) 
                    sleep 1
                    # puts variant.sku
                    newValueString << variant.sku
                    if index < 2
                        newValueString << "|"
                    end
                end

                #end of value save the newvaluestring to new csv
                csv << [newValueString]

            end
        end
    end
end

这是完成任务的简单方法:

begin
  variant = ShopifyAPI::Variant.find(vid)
rescue
  next
end

如果出现异常,则会发生救援事件。
