Hello everyone, I have to develop a cronjob in my app, it should run  
automatically every 2 hours, is there a way of doing it simply  
creating a rake task? I don’ t know how could I set the interval time  
for it. Do you know? Please help!

Hi Rodrigo,

Why don’t you just use cron?

Try looking into delayed\_job. It has lots of flexibility yet is pretty  
easy to use.

I recommend resque.
