有人知道如何从ActiveJob排队中获取 Delayed :: Job id吗？当我排队工作时，我得到一个 ActiveJob :: Base 的实例，该实例带有 @job_id ，但是该工作ID似乎在ActiveJob内部。到目前为止，我最好的猜测就是走最近创建的工作：

Any idea how to get the Delayed::Job id from the ActiveJob enqueuing? When I enqueue a job I get back an instance of ActiveJob::Base with a @job_id, but that job id seems to be internal to ActiveJob. My best guess so far is just to walk down the most recently created jobs:

active_job_id = GenerateReportJob.perform_later(self.id).job_id delayed_job = Delayed::Job.order(id: :desc).limit(5).detect do |job| YAML.load(job.handler).job_data['job_id'] == active_job_id end

但这似乎各种各样。有点惊讶的ActiveJob不会从 Delayed :: Job 返回ID，尤其是因为这是在作业入队时显式返回的。

but that seems all kinds of hacky. Kind of surprised ActiveJob isn't returning the ID from Delayed::Job, especially since that is what is explicitly returned when the job gets enqueued.

推荐答案

以防将来有人发现：Rails刚刚接受了一个补丁，使您可以从Rails 5的provider_job_id中获取此ID。您可以将其与

In case anyone finds this in the future: Rails just accepted a patch to allow you to get this id from provider_job_id in Rails 5. You can get it to work with a patch like

ActiveJob::QueueAdapters::DelayedJobAdapter.singleton_class.prepend(Module.new do def enqueue(job) provider_job = super job.provider_job_id = provider_job.id provider_job end def enqueue_at(job, timestamp) provider_job = super job.provider_job_id = provider_job.id provider_job end end)
