如何运行所有rake任务？ [英] How do I run all rake tasks?

问题描述

刚刚安装了gem https://github.com/javan/whenever 运行我的耙子任务，这是nokogiri / feedzilla相关的抓取任务。

Have just installed whenever gem https://github.com/javan/whenever to run my rake tasks, which are nokogiri / feedzilla dependent scraping tasks.

例如我的任务称为grab_bbc，grab_guardian等

eg my tasks are called grab_bbc, grab_guardian etc

我的问题 - 当我更新我的网站，我继续添加更多的任务给scheduler.rake。

My question - as I update my site, I keep add more tasks to scheduler.rake.

我应该在我的config / schedule.rb写什么，使所有rake任务运行，无论他们叫什么？

What should I write in my config/schedule.rb to make all rake tasks run, no matter what they are called?

会是这样的吗？

    every 12.hours do
        rake:task.each do |task|
            runner task
        end 
    end

使用RoR 4.

推荐答案

为每个刮削任务编写单独的rake任务。然后写一个聚合任务来运行所有这些刮擦耙子任务。

write separate rake tasks for each scraping tasks. then write a aggregated task to run all those scraping rake tasks.

desc "scrape nytimes"
task :scrape_nytimes do
  # scraping method
end

desc "scrape guardian"
task :scrape_guardian do
  # scraping method
end

desc "perform all scraping"
task :scrape do
  Rake::Task[:scrape_nytimes].execute 
  Rake::Task[:scrape_guardian].execute 
end

然后调用rake任务为

then call the rake task as

rake scrape
