ruby-on-rails - 开发环境中的 Rails delayed_job

Question

假设您在 Rails 中有一个带有操作的邮件程序，使用 delay 从某个模型调用，例如:

class ReportMailer < ActionMailer::Base

  default from: "hello@shopstar.co.za"

  def order_received(order)
    @order = order
    mail(:to => @order.shop.email, :subject  => "You have a new order on Shopstar")
  end
end

订单.rb:

      if self.shop.email_preference.on_order?
       ReportMailer.delay.order_received(self) unless self.source == "pos"
      end

这会从开发环境发送邮件吗？

和

这会在生产版本中发送邮件吗？

Answer 1

delayed job worker需要运行，

对于开发模式运行:

RAILS_ENV=development bundle exec bin/delayed_job start

你可能会遇到这样的错误:

bash: bin/delayed_job: No such file or directory

因此您必须生成运行该命令的 bin/delayed_job 文件:

bundle exec rails generate delayed_job                                                                                                                               

在生产环境中你应该运行:

RAILS_ENV=production bin/delayed_job start

以上命令适用于 Rails 4。对于 Rails 3，您应该:

script/delayed_job 而不是 bin/delayed_job
