Question

在perform方法中，我想知道当前作业的ID是什么。

例如，enqueue，success，failure和error方法提供job参数：

def enqueue(job)
  puts job.id
end

有可能吗？

Answer 1

我假设你使用sidekiq作为后端。在这种情况下，您可以执行以下操作：

def perform(*args)
  logger.info self.job_id
  # Do something later
end

这是日志输出

[ActiveJob] [RequestHandlerJob] [e9923650-cd02-40d1-937d-859852e92c61] e9923650-cd02-40d1-937d-859852e92c61

抱歉，错过了。

我在here

中找到了解决方案

# config/initializers/delayed_job.rb
Delayed::Worker.logger = Logger.new(File.join(Rails.root, 'log', 'dj.log'))


class RequestHandlerJob < ActiveJob::Base
  queue_as :default

  def perform(user_id)
    u = User.find(user_id)
    Delayed::Worker.logger.info self.job_id
    # Do something later
  end
end


[retgoat@iMac-Roman ~/workspace/tapp/log]$ tail -f dj.log

这是job_id 5f267272-8826-491d-b7d5-82a200e1a6b6。希望这会有所帮助。

Rails 4 - 延迟作业 - 是否可以在执行方法中知道作业ID？
