delayed_job fails jobs when running as a daemon. Runs fine when using rake jobs:work

Question

I am literally at my wits end with this. I don't understand why it isn't working.

I have made a class, which I call and queue using a rake command. When I run the worker using 'rake jobs:work' and call the command 'rake get_updates', it executes fine.

However, when I run the worker as a daemon (RAILS_ENV=production bin/delayed_job start) and call the command 'rake get_updates' it produces an error.

app/workers/get_updates.rb

class GetUpdates
    def perform

        beginning = Time.now

        include SoapHelper

        require 'nokogiri'
        require 'activerecord-import'

        product_count = 0
        contloop = true

        while(contloop == true) do

            @xml = Nokogiri::XML(get_unsent_data())
            @guid = @xml.xpath('.//Message').attr("Id")
            bulkUpdates = []

            if (@xml.xpath('.//Product').count > 0)

                @xml.xpath('.//Product').each do |p|

                    product_count += 1

                    update = Update.new
                    update.update_type = p.attr("UpdateType")

                    codes = Hash.new

                    p.children().each do |info| 

                        info.xpath('.//ProductCodes/Code').each do |coco|
                            codes[coco.attr("Scheme").to_s] = coco.content
                        end     

                        update.data = p.children().to_xml.to_s

                    end

                    bulkUpdates << update

                end

                if Update.import bulkUpdates

                else

                  puts "Error, data not saved"
                  contloop = false

                end

            else
                contloop = false
            end

        end

        @time = "Time elapsed #{Time.now - beginning} seconds"
        puts "Product Count: #{ product_count }"
        puts @time

    end

Answer 1

Try loading the class in an initializer:

# in config/initializers/delayed_job.rb
require 'get_updates'

That should make it available to the job.
