我想用 sidekiq 创建活动记录对象。我知道这不是最佳实践，因为我必须序列化整个对象，但在这种情况下没有其他选择。

如果我尝试一下，我会得到：

  EventTrackingWorker JID-ec2be02dae626dd19202b17f INFO: start
  EventTrackingWorker JID-ec2be02dae626dd19202b17f INFO: fail: 0.033 sec
  WARN: {"retry"=>false, "queue"=>"default", "class"=>"EventTrackingWorker", "args"=>["shift_created_event", {... long json object ..}}, "create"], "jid"=>"ec2be02dae626dd19202b17f"}
  WARN: undefined method `primary_key' for Hash:Class
  WARN: /Users/jedi/.rbenv/versions/1.9.3-p194-perf/lib/ruby/gems/1.9.1/gems/activerecord-3.2.11/lib/active_record/reflection.rb:366:in `primary_key'
  /Users/jedi/.rbenv/versions/1.9.3-p194-perf/lib/ruby/gems/1.9.1/gems/activerecord-3.2.11/lib/active_record/reflection.rb:216:in `association_primary_key'

错误说：WARN: undefined method `primary_key' for Hash:Class

使用此方法创建的对象（在本例中为事件）：

Track(:shift_created_event, {eventable: @shift, creator: current_user})

Track方法如下所示：

module EventTracking
  module_function

  def Track(event, options, method=:create)
    EventTrackingWorker.perform_async(event, options, method)
  end

end

EventTrackingWorker班级：

class EventTrackingWorker
  include Sidekiq::Worker

  def perform(event, options, method=:create)
    event.to_s.classify.constantize.new(options).send(method)
  end

end

注意：event.to_s.classify.constantize.new(options).send(method)将字符串转换shift_created_event为活动记录类并使用选项ShiftCreatedEvent调用。new之后我用.send(method)

有人有这方面的经验吗？
