Question

我通过邮递向用户发送邮件。这是我的控制人员守则:

@users = User.where(some condition)
@product = Product.find_by_name(some name).first
for user in @users
  UserMailer.new_product_arrival(user, @product, home_url).deliver
end

以及我的用户——电子邮箱:rb

def new_product_arrival(user,product,home_url)
  @from         = Settings.mailer_from_address
  @recipients   = user.login
  @sent_on      = Time.now
  @user = user
  @product = product
  @content_type = "text/html"
  @home_url = home_url
end

问题是,如果用户超过10个,则由于<<><>条码/代码>的路程而需要很长时间。我需要知道,我们是否能够通过利用多读或背景的工作来处理这一问题。我不想利用背景工作,但任何人都能够告诉我如何使用多读手段执行上述工作。

我正在使用废墟1.8.7和铁路3.07。

Answer 1

为了达到“多读”的目的,基本上有两个办法:

每一次分娩的配对器,并重新加入主线

threads = []
for user in @users
   threads << Thread.new do
     UserMailer.new_product_arrival(user, @product, home_url).deliver
   end
end
threads.each(&:join)

a. 在整个铁路上铺设叉(但满足请求的铁路将立即做出反应)并且使这一过程脱节:

process = fork do
  for user in @users
    UserMailer.new_product_arrival(user, @product, home_url).deliver
  end
  Process.kill("HUP") 
  #sends the kill signal to current Process, which is the Rails App sending your emails 
end
Process.detach(process)

Hope that helps

我们的开发商Artem 最近对

这使你能够很容易地寄送电子邮件,从而可以更快地发送电子邮件。检查结果。

Answer 3

Try

These tasks can happen asynchronously in the background, because your Rails app doesn t need them executed immediately.
