【问题描述】：

起初我有一个带有方法 email_coupon_sent 的 CastingMailer 类，我创建了带有邮件程序需要的所有东西的 CouponMailer 类，然后我将方法 email_coupon_sent 放在该类中，在我的工作中我调用 CouponMailer.email_coupon_sent，sidekiq 在日志中告诉我2017-02-14T15:42:05.066Z 7344 TID-ynsk0 WARN: NoMethodError: undefined method `email_coupon_sent' for CastingMailer:Class，为什么 sidekiq 一直在 CastingMailer 类中寻找 email_coupon_sent。

代码

admin_controller.rb

@coupon.give!
CouponSentJob.perform_later(@user.profileable, @coupon)

coupon_sent_job.rb

def perform(profile, coupon)
  # Send coupon to user
  Notification.notify_coupon_sent(profile, coupon)
  CouponMailer.email_coupon_sent(profile, coupon).deliver_now
end

coupon_mailer.rb

def email_coupon_sent(profile, coupon)
  @profile = profile
  @coupon = coupon
  mail(to: @profile.user.email, subject: I18n.t('views.mailers.coupon.coupon_sent.subject'))
end

views/coupon_mailer

email_coupon_sent.html.erb
email_coupon_sent.text.erb

sidekiq.log

在我的 CastingMailer 中目前没有 email_coupon_sent 方法

提前致谢。

【问题讨论】：

你是生产环境还是开发环境？进行更改后，您是否重新启动了 sidekiq？

【解决方案1】：

作业保存它需要调用的类和方法名。如果 Redis 中仍有作业引用它，则不能只重命名一个类。您必须确保也没有更多工作引用该名称。最简单的做法是刷新整个 Redis 数据库，但这会清除所有内容。
