delay_job thất nghiệp khi chạy như một daemon. Chạy tốt khi sử dụng các công việc cào: làm việc

Question

Tôi thực sự đã kết thúc với điều này. Tôi không hiểu tại sao nó không hoạt động.

Tôi đã tạo một lớp mà tôi gọi và xếp hàng bằng lệnh cào. Khi tôi chạy công nhân bằng cách sử dụng 'rake jobs: work' và gọi lệnh 'rake get_updates', nó thực hiện tốt.

Tuy nhiên, khi tôi chạy công nhân làm daemon (RAILS_ENV = bin sản xuất/trì hoãn bắt đầu) và gọi lệnh 'rake get_updates', nó tạo ra lỗi.

ứng dụng/công nhân/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 

        acknowledge_soap_receipt(@guid.to_s) 

       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 
end 

clockwork.rake

task :get_updates => :environment do 

    Delayed::Job.enqueue GetUpdates.new 

end 

đường Autoload trong 'application.rb'

config.autoload_paths += %W(#{config.root}/app/workers)

Answer 1

Thử tải các lớp trong một initializer:

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

Điều đó sẽ làm cho nó có sẵn cho công việc.
