Rails - Apr 2006 - how can I access a class variable outside of the class???

Hi 

we wanted to access a class varaible from outside of
the same class, like 

class klass
   @@var1
end

we found out we can not use the class variable like
this: 
klass.var1 we have to create a class function like


class klass
   @@var1
  
   def var1
     return @@var1
   end

end


If anyone know how to access a class variable directly
without passing by a function???

Thanks you very much

" Class variables are private to a class and its instances. If you want to
make them accessible to the outside world, you''ll need to write an
accessor
method. This method could be either an instance method or, leading us neatly
to the next section, a class method. "

Try

cattr_accessor :some_var

works just like attr_accessor except for class variables.
