使用Ruby on Rails安排发送电子邮件任务的最佳方法是什么？

I would like to schedule a daily task : every day at 7 AM, I want an email to be sent (without human intervention).

我想安排一项日常任务：每天早上7点，我都希望发送一封电子邮件（无人为干预）。

I'm working on the RoR framework and I'm wondering what is the best way to do that?

我正在研究RoR框架，我想知道最好的方法是什么？

I've heard about BackgrounDRB, OpenWFEru scheduler or things based on Cron, but I'm a newbie and don't understand which one is made for my need.

我听说过BackgrounDRB，OpenWFEru调度程序或基于Cron的东西，但我是新手，不明白哪一个是为我的需要而制作的。

Another option is to create a rake task that is run by a cron job. To do this, create a file some_file.rake and put it in your lib/tasks folder. Your file might look like this:

另一种选择是创建由cron作业运行的rake任务。为此，请创建一个文件some_file.rake并将其放在lib / tasks文件夹中。您的文件可能如下所示：

Rails 2.x:

Rails 2.x：

task :send_daily_mail, :needs => :environment do
    Model.send_daily_mail
end

Rails 3.x:

Rails 3.x：

task :send_daily_mail => :environment do
    Model.send_daily_mail
end

Then use cron to execute it as often as you like:

然后使用cron随意执行它：

cd /path/to/app && /usr/bin/rake send_daily_mail

Note you might need to put RAILS_ENV=production in your crontab if your app is in development mode by default.

请注意，如果您的应用默认处于开发模式，则可能需要在您的crontab中放置RAILS_ENV = production。

I was impressed by (and plan to try) the rufus-scheduler gem discussed in this blog post

我对此博客文章中讨论的rufus-scheduler gem印象深刻（并计划尝试）

He describes something like this:

他描述了这样的事情：

scheduler = Rufus::Scheduler.start_new  

scheduler.every("1m") do  
   DailyDigest.send_digest!  
end

..which seems pretty simple. I wonder how easy it would be to add HTML-based configuration?

..这似乎很简单。我想知道添加基于HTML的配置有多容易吗？

BackgroundRB is what I use and it works perfect. I have several emails being sent, generated by BackgroundRB. I also have other tasks as well. Because it enables both scheduled tasks and asynchronous tasks (tasks that take longer than the normal client/server response cycle).

BackgroundRB是我使用的，它完美无缺。我发送了几封由BackgroundRB生成的电子邮件。我也有其他任务。因为它支持计划任务和异步任务（比正常客户端/服务器响应周期花费更长时间的任务）。

I use it and I am very happy with it.

我用它，我很高兴。

Add a class method to one of your models that will handle this for you. Now try to execute that method using the runner script

将类方法添加到您将为您处理此问题的模型之一。现在尝试使用runner脚本执行该方法

./script/runner "MyModel.send_daily_mail" RAILS_ENV=production

Ensure everything works ok. If it does, then we need to make the command work universally by setting up the path to the project properly.

确保一切正常。如果是这样，那么我们需要通过正确设置项目的路径来使命令普遍运行。

cd /path/to/my/rails/project && ./script/runner "MyModel.send_daily_mail" RAILS_ENV=production

Now change to any random directiry and run that command. If it runs properly, run crontab -e and insert the command in there setup to run daily at 7AM. There are a ton of explanation about the cron format on there if you google for them and should be pretty simple to figure out.

现在更改为任何随机方向并运行该命令。如果它正常运行，请运行crontab -e并在该设置中插入命令，以便每天早上7点运行。如果你谷歌的话，那里有关于cron格式的大量解释，应该很容易理解。

Go with a rake task and cron job, as the accepted answer already says. However, note that, updating the cron file itself is a manual task. That may be fine if you are not changing it during development. Otherwise, here how you can let Capistrano do it for you: http://push.cx/2008/deploying-crontab-with-your-rails-app

接受rake任务和cron工作，正如已接受的答案已经说明的那样。但请注意，更新cron文件本身是一项手动任务。如果您在开发过程中没有更改它，那可能没问题。否则，在这里你可以让Capistrano为你做这些：http：//push.cx/2008/deploying-crontab-with-your-rails-app
