The Purpose of Active Job

积极工作的目的

The main point is to ensure that all Rails apps will have a job infrastructure in place, even if it's in the form of an "immediate runner". We can then have framework features and other gems build on top of that, without having to worry about API differences between various job runners such as Delayed Job and Resque. Picking your queuing backend becomes more of an operational concern, then.

重点是确保所有Rails应用程序都有一个就业基础设施,即使它是“直接跑步者”的形式。然后我们可以在此基础上构建框架功能和其他宝石,而不必担心各种作业运行程序(如Delayed Job和Resque)之间的API差异。那么,挑选你的排队后端就变得更加困难了。

After comparison, I found that 'rufus-scheduler' is most friendly to use.

Add it in gemfile, run 'bundle install', then create a file named 'scheduler.rb' in /config/initializer, then put code in it(see the examples), done!

将它添加到gemfile中,运行'bundle install',然后在/ config / initializer中创建一个名为'scheduler.rb'的文件,然后将代码放入其中(参见示例),完成!
