I have a database that is populated based on events that happen in real-time. I wanted to view the output of reports from that database on a regular basis (every 30 seconds). I found a lovely little gem called ‘rufus-scheduler’ that does the trick nice and neatly. Here’s how it worked for me.
Add the gem to your Gemfile
Update your bundle with bundle install
/path/to/my/app/$ bundle install
Create a file in your initializers folder. I’ve called mine task_scheduler. This file contains instructions to start the scheduled background process and on the tasks you want to run regularly.
The contents of mine are as follows:
scheduler = Rufus::Scheduler.start_new
stats_direct = Stats.new("Frankston Direct")
stats_loop = Stats.new("Frankston Loop")
stats_loop = Stats.new("Sandringham")
And that’s all there is to it.
