Hi,  
Is it possible to write two class in one controller?  
e.g:-

class ApplicationController \< ActionController::Base  
def abc  
end  
end  
class Hash  
def xyz  
end  
end

How it will work?

Thanks,  
Tushar.

A file can define as many classes as you want. Rails’ automatic  
loading of files for you will only be able to locate a class if it is  
in the file with the appropriate name.
