Hi,  
I created a calendar class and i now have a method which gives me a 1  
day view with timeslots etc. now i want to re-use that code for  
generating 2 and 5 day views. how can i re-use my code so i can make a  
show\_two\_days class which uses the logic of the show\_one\_day class?

am i correct it can’t be done with helpers?

regards,

Remco

I dunno if I understand you but you might have a look to  
render\_component

If they’re in the same controller, one method can call another. If  
not, put the shared method in application.rb and it becomes available  
from every controller.
