Rails - Dec 2007 - Extending ActiveRecord::Base

So I have a function that I want all my models to have access to.  I''ve
done some reading and looked for pages and they all say you can extend
ActiveRecord::Base, and then all your models will get the extra
function.  "Easy" thinks I.  I must be missing something.

Here is what I''ve tried:

In lib, I created an active_directory folder and then in there made a
base.rb file.  The file looks like this:

class ActiveRecord::Base
  def some_function(param)
        do some stuff
  end
end

Then, in /config/environment.rb I have require
''active_record/base.rb''

Well, that blew up spectacularly, and I couldn''t get script/server to
run.  So I renamed it DB/base.rb and changed the require to reflect
that.  Now script/server runs, but when I try to call some_function from
one of my models, it complains that ''method_missing'':
undefined method
''some_function'' for SomeModel:Class (NoMethodError).

I''ve tried doing this for base.rb instead:

module ActiveRecord
  class Base
    def some_function(param)
       do some stuff
    end
  end
end

and it still complains.

I even tried the following for base.rb:

module ActiveRecordCommon
  def some_function(param)
    do some stuff
  end
end

Then in the /config/environment.rb I did:

require ''DB/base.rb''
class ActiveRecord::Base
  include ActiveRecordCommon
end

And even THAT didn''t work.

I''m all out of ideas.  All the examples I''ve seen have been
like the
ones I''ve described here.  I know I''m missing something
simple, as that
tends to be the case.  Could someone please point it out to me?

Thanks.

I''m no expert but my guess is that if you''re intending your
method to
be a class method, then you need to prefix the method name with
"self."
