我该如何使用副业工人？

Question

我有一个应用程序，在其中我可以创建发票，渲染成pdf和发送给客户。我的邮件中有两个动作：

class InvoiceMailer < ActionMailer::Base
  default from: "from@example.com"

  def send_invoice_reminder(invoice)
    @invoice = invoice
    attach_invoice
    mail :subject => "Invoice reminder", :to => invoice.customer.email
  end

  def send_invoice(invoice)
    @invoice = invoice
    attach_invoice
    mail :subject => "Your Invoice", :to => invoice.customer.email
  end

  protected
  def attach_invoice
    attachments["invoice.pdf"] = WickedPdf.new.pdf_from_string(
      render_to_string(:pdf => "invoice",:template => 'admin/invoices/show.pdf.erb')
    )
  end
end

现在我想通过Sidkiq工人发送这个。但我有疑问。我是否需要两个帮手：

• 一封寄发票电子邮件
• 第二，发送提醒

或者一个工人就够了？

Answer 1

我想你可以用一个工人来做这两件事，因为在这两件事上，你的工作基本上是一样的。

它看起来像：

class InvoiceMailer < ActionMailer::Base
  default from: "from@example.com"

  def send_invoice(invoice, subject)
    @invoice = invoice
    attachments["invoice.pdf"] = pdf
    mail subject: subject, to: invoice.customer.email
  end

  private

  def pdf
    WickedPdf.new.pdf_from_string render_to_string(
        pdf: "invoice",
        template: 'admin/invoices/show.pdf.erb'
    )
  end
end

class InvoceEmailSender
  include Sidekiq::Worker

  def perform(invoice, subject)
    InvoiceMailer.send_invoice(invoice, subject).deliver
  end
end

InvoiceEmailSender.perform_async invoice, 'Your Invoice'
InvoiceEmailSender.perform_async invoice, 'Invoice Reminder'
