我正在使用发条宝石发送每日电子邮件。我在 lib 文件夹中创建了 clock.rb 文件。

  #clock.rb
  require 'rubygems'
  require 'clockwork'
  include Clockwork

  every(1.day, 'reminders.send', :at => '09:30'){
   @leave_details = LeaveDetail.all(:conditions => {:status => [LeaveDetail::STATUS_PENDING, LeaveDetail::STATUS_PENDING_MNGT]})
   @leave_details.each do |ld|
   UserMailer.leave_reminder_email(ld).deliver
 end
}

我创建了一个 Procfile:-

web:    bundle exec thin start -d
clock:  bundle exec clockwork lib/clock.rb

当我命令

foreman start

它显示错误：-

LeaveDetail 是模型内部的一个 ruby​​ 类。谁能告诉我为什么'LeaveDetail'在这里显示未初始化？谢谢

您实际上并没有在发条中加载您的应用程序。Clockwork 是一个独立的 ruby​​ 进程。如果你不告诉它你的应用程序的其余部分，它不知道它的存在，所以你的错误是合乎逻辑的。这是来自sidekiq 的发条示例文档：

# require boot & environment for a Rails app
require_relative "../config/boot"
require_relative "../config/environment"

您可以include Clockwork用作模块，添加require './config/boot' 和require './config/environment'

require './config/boot'
require './config/environment'
require 'clockwork'

module Clockwork
every(1.day, 'reminders.send', :at => '09:30'){
   @leave_details = LeaveDetail.all(:conditions => {:status => [LeaveDetail::STATUS_PENDING, LeaveDetail::STATUS_PENDING_MNGT]})
   @leave_details.each do |ld|
   UserMailer.leave_reminder_email(ld).deliver
 end
}
end
