私は今、私のレール3 heroku appでw/o問題をしばらく遅延ジョブを使用してきました。先日、それはすべての仕事にerror'dしました。今私は最後のエラーで遅れた仕事の記録に立ち往生していますが、解決するために調査する方法に固執しています。ここでrails - Delayed Job - 失敗したジョブをデバッグする最良の方法
は誤りです：
>> Delayed::Job.find(:last)
=> #<Delayed::Backend::ActiveRecord::Job id: 411, priority: 0, attempts: 15, handler: "--- !ruby/struct:Delayed::PerformableMailer \nobject...", last_error: "{uninitialized constant Attachment::AWS\n/disk1/home...", run_at: "2010-12-31 06:32:52", locked_at: nil, failed_at: nil, locked_by: nil, created_at: "2010-12-29 04:58:45", updated_at: "2010-12-30 16:29:02">
