使用Sidekiq和Sidetiq发送重复的电子邮件

Question

我在使用Sidekiq和Sidetiq发送重复邮件时遇到了问题。我几乎什么都试过了，但还是找不到解决方案。我有一个Sidekiq worker，它看起来像这样：

class InvoiceEmailSender
  include Sidekiq::Worker
  include Sidetiq::Schedulable

  recurrence {minutely(2)}
  def perform(invoice_id, action)
    @invoice = Invoice.find(invoice_id.to_i)
    if action == "invoice"
      send_invoice
    else
      send_reminder
    end
  end

  private
  def send_invoice
    if @invoice.delivery_date == Date.today
      InvoiceMailer.delay.send_invoice(@invoice)
    else
      InvoiceMailer.delay_for(@invoice.delivery_date.to_time).send_invoice(@invoice)
    end
  end

  def send_reminder
   InvoiceMailer.delay.send_invoice_reminder(@invoice) unless @invoice.paid?
  end
end

在控制器中结束我这样使用它：

InvoiceEmailSender.perform_async(@invoice.id, "invoice")

当我尝试发送此电子邮件时，在sidekiq控制台中出现以下错误：

在sideiq web监视器的scheduled选项卡中，它看起来像这样：

请帮忙，因为我不知道发生了什么.

传入的数据看起来像纪元时间戳，结果是Sidetiq将上一次和当前时间作为2个参数传递给你的worker，according to the documentation。

我不确定你是如何对一个调度的worker进行自定义参数的，你可能需要一个不同的策略，比如不是尝试创建更多的调度worker，而是只有1个(或2个，因为看起来你让这个类做了2个作业)的调度worker来处理每隔一段时间要做的工作列表。
