Question

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

显示错误： -

LeaveDetail是模型中的ruby类。任何人都可以告诉我为什么'LeaveDetail'在这里显示未初始化？ thnks

Answer 1

您实际上并没有在发条中加载您的应用。发条是一个单独的独立红宝石过程。如果您没有告诉它应用程序的其余部分，它不知道它的存在，因此您的错误是合乎逻辑的。这来自sidekiq's clockwork example documentation：

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

Answer 2

您可以使用include Clockwork作为模块，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

发条不与Foreman合作
