達萊伊德爾伊德工作執行已過期發送電子郵件

Question

我使用延遲作業寶石發送使用亞馬遜SES的電子郵件。但它偶爾會運行到execution expired錯誤。可能有一些連接問題SES。我想知道如何捕獲這個異常並手動重新安排電子郵件？由於內部原因而被推遲作業配置爲單一最大嘗試

Answer 1

delayed_jobprovides some hooks，您可以使用error鉤改期任務。

def error(job, exception) 
    # if exception is the one occurring right now for expired execution 
    # reschedule the job 
    # be careful to avoid infinite rescheduling 
end
