Question

我正在尝试在生产中发送邮件，但它正在抛出Activejob deserailization error.sidekiq正在后台运行。我添加了sidekiq gem。我在comment_notification.rb中编写了一个方法，用于向用户发送电子邮件。然后在创建动作的控制器中我添加了这个

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 => "<noreply@xxx.com>")
end

它在本地服务器上工作正常，但在生产中我收到此错误

有人可以帮我解决这个疑问吗？为此，我将感激不尽。

据我所知，控制器中的create方法也会创建注释并发送新创建的评论的电子邮件？

那么最好在这里使用回调我们在项目中遇到了同样的问题，我们通过使用类似的东西来解决它：

# in model
after_commit :send_mail, on: :create

private

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

然后，您可以确保在邮件发送之前，记录确实存在于数据库中。

这里的问题是，您运行Comment#create并将控制器中的邮件入队。现在可能发生，Sidekiq在Rails提交新评论之前完成任务然后你就得到了这个错误。
