Question

我的问题很简单

使用自定义类，我可以做到这一点：

class Job
  def message=(message)
    @message = message
  end

  def perform
    puts @message
  end
end

job = Job.new
job.message = 'hello'
Delayed::Job.enqueue job
Delayed::Job.last.invoke_job
# hello
# => nil

使用ActiveJob::Base类时，我不能：

job = MyJob.new

class MyJob < ApplicationJob
  def message= (message)
    @message = message
  end

  def perform(*args)
    puts @message
  end
end

job = MyJob.new
job.message = 'hello'
job.enqueue
Delayed::Job.last.invoke_job

# Performed MyJob (Job ID: a8cadf34-f7f7-406d-abcf-cd96589acdf2) from DelayedJob(default) in 3.58ms
# => nil

原因是JobWrapper（不包含自定义属性）被插入表中而不是作业实例本身：

Delayed::Backend::ActiveRecord::Job Create (0.5ms)  INSERT INTO "delayed_jobs" ("handler", "run_at", "queue", "created_at", "updated_at") VALUES ('--- !ruby/object:ActiveJob::QueueAdapters::DelayedJobAdapter::JobWrapper
job_data:
  job_class: MyJob
  job_id: a8cadf34-f7f7-406d-abcf-cd96589acdf2
  provider_job_id: 
  queue_name: default
  priority: 
  arguments: []
  executions: 0
  locale: en
', '2018-10-23 16:34:58.363428', 'default', '2018-10-23 16:34:58.363570', '2018-10-23 16:34:58.363570') RETURNING "id"

我知道perform_later语法和其他相关详细信息，请不要只是告诉我“您使用错了” 。

这是预期的行为还是被禁止？如果没有，有什么解决方法吗？

ActiveJob实例变量未存储在DelayedJob
