我在 Heroku 中正确运行我的 cron 任务吗？

不确定我这样做是否正确。阅读：http://devcenter.heroku.com/articles/cron#frequently-asked -questions

如果我有 cron 每 24 小时在 Heroku 上运行一次。它会每 24 小时运行一次 def foo 和 def bar 吗？或者我应该用 if Time.now.hour % 24== 0 # run every 24 hour 包装这两个方法？

desc "This task is called by the Heroku cron add-on"
task :cron => :environment do

  def foo
    puts 'foo'
  end

  deb bar
    puts 'bar'
  end

end

其次，如何在本地计算机上运行此 cron 作业（可能通过控制台或其他方法）？

附言。我在 Cedar 堆栈上运行 Rails 3.1 RC5。

Not sure if I am doing this right. Reading: http://devcenter.heroku.com/articles/cron#frequently-asked-questions

If I have cron running every 24 hours on Heroku. Will it run def foo and def bar every 24 hours? Or should I wrap both methods with if Time.now.hour % 24== 0 # run every 24 hours?

desc "This task is called by the Heroku cron add-on"
task :cron => :environment do

  def foo
    puts 'foo'
  end

  deb bar
    puts 'bar'
  end

end

Second, how can I run this cron job on my local machine (possibly via console or other method)?

PS. I am running Rails 3.1 RC5 on the Cedar stack.

如果您将 cron 设置为“每日”，那么它将每 24 小时运行一次，无需在其中添加 if 语句。

要在本地运行 cron 任务，只需执行 rake cron

编辑：

您还需要调用您在其中定义的方法，因为当前 cron 所做的只是定义 foo 和 bar：

desc "This task is called by the Heroku cron add-on"
task :cron => :environment do

  def foo
    puts 'foo'
  end

  def bar
    puts 'bar'
  end

  foo
  bar

end

If you've set up the cron as "daily" then it will run every 24 hours, there's no need to put an if statement in there.

To run the cron task locally just do rake cron

Edit:

You'll also need to call the methods you've defined in there as currently all your cron does is define foo and bar:

desc "This task is called by the Heroku cron add-on"
task :cron => :environment do

  def foo
    puts 'foo'
  end

  def bar
    puts 'bar'
  end

  foo
  bar

end
