Rails - Mar 2005 - overriding ActiveRecord::Base.instantiate

Hi all.  Maybe this is more of a Ruby question than Rails, but here it goes 
anyways.  

I want some object types to be instantiated in a special way, so I override 
the instantiate method.  The catch is that since I want to use the same 
instantiate method in several classes I thought I''d put it in a module
like
so:
module ViewCTI
  self.instantiate(record)
    ...
  end
end

But I can''t get the method to be inserted into my class.  I thought
something
like
class MyClass < AR::Base
  include(ViewCTI)
end
or 
class MyClass < AR::Base
  self.extend(ViewCTI)
end
should do it, but it doesn''t look that way.  Is there a method to
import the
module methods into the class?

Thanks

Luca

I''m still new at this Ruby thing myself, so I could be wrong.  Try

module ViewCTI
  def instantiate(record)
    ...
  end
end

class MyClass < ActiveRecord::Base
  extend ViewCTI
end

Depending on what you are trying to do, it may be more appropriate to do
this:

module ActiveRecord
  class MyBaseClass < ActiveRecord::Base
    def self.instantiate(record)
      ...
    end
  end
end

class MyClass << ActiveRecord::MyBaseClass
  ...
end

I''m currently using both techniques to override other AR methods with
great
success.
