association extend rails 2 feature

I've been looking on the internet for the feature in rails where you can specify an association extend module on the actual class.

So for example

class Printer < AR::Base   some_association_extend_method_that_i_cant_figure_out do     def (value)       find_by_name(value)     end   end end class Product < AR::Base   has_many :printers end

product.printers["name"] # <-- should return the printer if it exists Product["name"] # <-- should work as well.

Does anyone know what im talking about? I saw it once, I can't find it again.

Maybe you're looking for has_finder or, in Rails 2.1, named_scope.
