ruby-on-rails - 作业加载失败 : uninitialized constant with Delayed Job and Rails 3

Question

我正尝试在我的 Rails 3 应用程序中使用延迟作业，但一直遇到障碍。作业不断失败并显示错误:Job failed to load: uninitialized constant CrawlJob.

我找到了其他几个 SO 线程，并按照那里的建议无济于事。这是相关代码。

Application.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'

...

module Decurate
  class Application < Rails::Application

...

    config.autoload_paths += %W(#{config.root}/lib)
    config.autoload_paths += Dir["#{config.root}/lib/**/"]

...

  end
end

/lib/crawl_job.rb

class CrawlJob < Struct.new(:merchant_id,:ec2,:s3)
  def perform

...

  end
end

/lib/tasks/cron.rake

  merchants = Store.all.collect{ |store| store[:merchant_id] }
  merchants.each do |merchant_id|
    queue.push merchant_id
  end
  merchants.each do |merchant_id|
    Delayed::Job.enqueue CrawlJob.new(merchant_id,@ec2,@s3)
  end

抱歉大家，似乎我只是忘记了重新启动我的工作进程，因为我在处理 autoload_paths。作为引用，上述安排应该有效。请记住使用 rake jobs:work 启动一个新的 worker!
