ActiveJob :: DeserializationError：嘗試反序列化參數時出錯

我試圖在生產中發送郵件，但它拋出Activejob deserailization error.sidekiq在後臺運行。我已添加sidekiq寶石。我在comment_notification.rb中寫了一個用於發送電子郵件給用戶的方法。然後，在創建動作控制器我加入這個ActiveJob :: DeserializationError：嘗試反序列化參數時出錯

def create 
    CommentNotification.send_comment_mail(@current_user).deliver_later(wait: 1.minute) 
end 


def send_comment_email(current_user) 
    mail(to: current_user.email, 
    :subject => "commented on post", 
    :from => "<[email protected]>") 
end

這是工作的罰款在本地服務器，但在生產中我得到這個錯誤

現在，當您發佈的錯誤，閱讀它，尤其是這部分'錯誤嘗試反序列化參數：無法找到「身份證」 = 40'評論。它不是給你一個解決問題的提示嗎？ –

id在數據庫中有40個，註釋也在創建中。唯一的問題是郵件沒有被觸發。 – asha

據我瞭解，控制器中的create方法也創建了評論併發送新創建的評論的電子郵件？

然後在這裏使用回調會更好。
我們在我們的項目中同樣的問題，我們通過這樣的事情解決它：

# in model 
after_commit :send_mail, on: :create 

private 

def send_mail 
    CommentNotification.send_comment_mail(campaign.user).deliver_later 
end

然後你就可以確保記錄確實存在於數據庫中的郵件被交付之前。

這裏的問題是，你運行一個Comment#create並將郵件排入控制器。現在可能發生，Sidekiq在Rails提交新評論之前運行該任務。
然後你會得到這個錯誤。

問候，

我們可以把它寫在控制器中嗎？例如：after_action：發送電子郵件，只：[：create] – asha

您可以。但是你應該使用'CommentNotification.send_comment_mail（campaign.user）.deliver_later（wait：5.minutes）'或類似的。對於after_commit和上面的方法都不起作用的 – Spa

。仍然顯示相同的錯誤。 – asha
