Question

我正在使用Delayed_Job从API中获取Twitter用户的数据，但由于某种原因，它并没有将其保存在模型中！请帮忙！（以下代码）

class BandJob < Struct.new(:band_id, :band_username) #parameter

  def perform
    require 'json'
    require 'open-uri'
    band = Band.find_by_id(band_id)
    t = JSON.parse(open("http://twitter.com/users/show/#{band_username}.json").read)
    band.screen_name = t['screen_name']
    band.profile_background_image = t['profile_background_image_url']
    band.url = 'http://' + band_username + '.com'
    band.save!
  end

端

为了澄清，我实际上没有得到任何错误，它只是没有保存。这是我的日志的样子：

* [JOB] acquiring lock on BandJob

谢谢！

Answer 1

我遇到了同样的问题并且弹出了延迟的工作，而我的服务器也解决了这个问题。

Answer 2

在初始值设定项中设置Delayed::Job.destroy_failed_jobs = false，然后查看数据库中的delayed_jobs表。查找last_error错误列 - 它将具有堆栈跟踪，以便您可以诊断问题。

您可能还对delayed_job_admin插件感兴趣，该插件添加了一个控制器来查看作业。

Answer 3

想出来。

这实际上是Console和Delayed_Job一起玩不好的问题。我不得不在控制台中重新定义变量，但它反映了模型中的变化。哎呦。
