Question

我正在爲簡單電子郵件通知設置後臺任務，使用Rails 5和DelayedJob。

展望我的生產記錄和它的未來了以下項目：

[2016-08-05T20:22:15.094172 #10616] DEBUG -- : 
Delayed::Backend::ActiveRecord::Job Load (1.0ms) UPDATE "delayed_jobs" 
SET locked_at = '2016-08-06 10:22:15.092656', locked_by = 'delayed_job 
host:jiably pid:10616' WHERE id IN (SELECT "delayed_jobs"."id" FROM 
"delayed_jobs" WHERE ((run_at <= '2016-08-06 10:22:15.091986' AND 
(locked_at IS NULL OR locked_at < '2016-08-06 06:22:15.092073') OR 
locked_by = 'delayed_job host:vps-server-name pid:10616') AND failed_at IS NULL) ORDER BY priority ASC, run_at ASC LIMIT 1 FOR UPDATE) RETURNING * 

有隊列中沒有工作，當我測試我的應用程序的電子郵件通知的工作似乎要處理的罰款。

這是正常的嗎？它似乎經常重複並添加到日誌文件中。我確實有logrotate設置，但不確定它是否是我做或錯過的配置。

感謝您對此有所瞭解。

您可能會看到Delayed :: Job issue 477 here。編輯：我知道你說這發生在生產。修復程序或您的配置需要修改以符合該關注點。

如果是這樣，修復程序就在那裏。我在這裏實現了config/initializers/delayed_job_config.rb（注意我已經實現了分段）：

Delayed::Worker.max_attempts = 5 
Delayed::Worker.delay_jobs = !Rails.env.test? 
Delayed::Worker.sleep_delay = 10 
Delayed::Worker.default_priority = 100 

# Prevent excessive logging every 5 seconds when Logger level < WARN 
# https://github.com/collectiveidea/delayed_job/issues/477 
if %w(development staging).include? Rails.env 
    module Delayed 
    module Backend 
     module ActiveRecord 
     class Job 
      class << self 
      alias_method :reserve_original, :reserve 
      def reserve(worker, max_run_time = Worker.max_run_time) 
       previous_level = ::ActiveRecord::Base.logger.level 
       ::ActiveRecord::Base.logger.level = Logger::WARN if previous_level < Logger::WARN 
       value = reserve_original(worker, max_run_time) 
       ::ActiveRecord::Base.logger.level = previous_level 
       value 
      end 
      end 
     end 
     end 
    end 
    end 
end
