Call methods from ApplicationController from a cron job


Can code in my cron job call methods from ApplicationController? It needs to act as if a user called a function, which triggers a whole lot of code that I have in the controller. I don't want to separate this to a library, because this way, the controller will look pretty messy.

Is there any was I can require the application controller and then call its methods from the cron job?

What I'm getting now is just: NoMethodError: undefined method `create_message_in_chat' for #<PeriodicChecker:0xb6cc7b9c>

Thanks, Helzer
