我真的以我的智慧结束了这一点。我不明白为什么它不起作用。
我创建了一个类，我使用rake命令调用并排队。当我使用'rake jobs：work'运行worker并调用命令'rake get_updates'时，它执行正常。
但是，当我将worker作为守护进程运行（RAILS_ENV =生成bin / delayed_job start）并调用命令'rake get_updates'时，会产生错误。
应用/工人/ 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

contloop = false

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

end

答案 0 :(得分：4)
尝试在初始化程序中加载类：
# in config/initializers/delayed_job.rb
require 'get_updates'
这应该让它可以用于工作。
