Hello,

Right now, my Rails app has a controller with far too many functions.  
Some of these functions look like:

def generic\_function(params)  
case x  
when “module1”  
return module1\_function(params)  
when “module2”  
return module2\_function(params)  
[…]  
end  
end

I would like to move module1\_function (and all other module1 related  
stuff) in a separate file. Same thing for module2 (in another  
separate file) and so on. What is the proper, clean way to do that?

Thanks,  
Karine
