Question

我需要按需发送电子邮件的内容。

我的应用程序中的每个用户都应该能够设置他定期收到电子邮件的日期和时间，提醒他或她必须服用药物。

是否可以使用自定义守护程序处理此问题？我想是这样，但这是我第一次使用这些东西，我需要你的意见才能在开始之前确定。

非常感谢，伙计们。

medicine_worker.rb：

class MedicineWorker
  include Sidekiq::Worker
  sidekiq_options retry: false

  def perform(name, count)
    puts 'Doing hard work'
  end

end

redis.rb：

# bundle exec sidekiq
$redis = Redis.new(:host => 'localhost', :port => 6379)

您最好使用后台队列，最好是具有调度选项的后台队列。

Sidekiq非常适合您的需求。
