ruby - 使用 iron_worker_ruby gem 时在 Iron Worker 中的继承

Question

我正在考虑将 IronWorker 用于一个项目，以便我可以轻松地扩展它(预期高流量，有很多后台作业)。

为了保持 DRY，我尝试使用继承来定义工作人员，但我不断收到以下错误:

/usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- base_worker.rb (LoadError)
    from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /task/child_worker.rb:3:in `<top (required)>'
    from /task/runner.rb:344:in `require_relative'
    from /task/runner.rb:344:in `<main>'

这是基本 worker 类:

#  app/workers/base_worker.rb
require 'net/http'
require 'uri'
require 'json'

class BaseWorker < IronWorker::Base
  attr_accessor :params

  # The run method is what IronWorker calls to run your worker
  def run
    data = custom_run(params)
    common_post_process(data)
  end

   def custom_run(params)
     #to be overwritten in the child class 
   end    

   def common_post_process(data)
      # some common post processing => DRY
      ....
   end       
end

这是一个子类:

# app/workers/child_worker.rb 
require 'net/http'
require 'uri'
require 'base_worker.rb'

class ChildWorker  <  BaseWorker
  merge "base_worker.rb"

  def custom_run(params)
     #custom work
  end

end

知道如何解决这个问题吗？

我建议使用我们的下一代 gem，iron_worker_ng:https://github.com/iron-io/iron_worker_ruby_ng . iron_worker gem 已弃用。如果你想让它保持与你所拥有的相似的风格，你的 child_worker.rb 可能看起来像这样:

require 'net/http'
require 'uri'
require_relative 'base_worker.rb'

class ChildWorker  <  BaseWorker

  def custom_run(params)
     #custom work
  end

end

# NG gem doesn't run anything in particular, so to run your method:
cw = ChildWorker.new
cw.custom_run(params)

在 child_worker.worker 文件中:

runtime 'ruby'

file 'base_worker.rb'
exec 'child_worker.rb'

然后将其上传到 IronWorker:

iron_worker upload child_worker

然后你就可以开始为它排作业了:

worker = IronWorkerNG::Client.new
worker.tasks.create("child_worker", params)
