Automatically run ruby script after server load - Ruby on Rails

Question

I have a file named Cron.rb located in app/lib.

To execute the file I do something like this.

Cron.run

This executes a method which creates a thread and processes cron jobs that I have programmed into the file.

I want a graceful way of automatically starting this Cron.run function when rails is started in either development or production. I can't use a cron Job to start this file. I want it to start alongside the current instance of ActiveRecord with all the other Models, etc.

Why don't you add something to config/initializers ? startup_cron.rb which contains Cron.run ? — SteveTurczyn

If you want to execute code when rails is started, add an initializer.

It just needs the one line you want to execute.

config/initializers/startup_cron.rb

Cron.run
