Rails - Jan 2011 - different load order in rails console vs rspec tests?

I''ve written a simple module to extend ActiveRecord::Base, which works
fine in the rails console but fails miserably in rspec tests.  The
intended usage looks like this:

class Premise < ActiveRecord::Base
  has_my_extensions
end

I''ve traced it down to the fact that in the console, it loads
lib/my_extensions.rb before it loads premise.rb.  In rspec, it''s
attempting to load premise.rb without loading my_extensions.rb, which
(naturally) results in a method_missing error.

(A) has anyone else seen this?
(B) what''s the proper remedy?

Details below the sig.  Thanks...

Some particulars: Ruby 1.9.2.  Rails 3.0.3.  RSpec 2.4.0.

=== file: $ROOT/config/environment.rb
require File.expand_path(''../application'', __FILE__)
Demo::Application.initialize!
require ''my_extensions''
=== EOF

=== file: $ROOT/app/models/premise.rb
$stderr.puts(Rails.logger.debug("==== loading #{__FILE__}"))
class Premise < ActiveRecord::Base
  has_my_extensions
  def test_one
    extension_one
  end
end
=== EOF

=== file: $ROOT/lib/my_extensions.rb hews to a familiar pattern:
$stderr.puts(Rails.logger.debug("==== loading #{__FILE__}"))
module MyExtensions
  def self.included(base)
    base.extend(ClassMethods)
  end

  module ClassMethods
    def has_my_extensions
      send(:include, InstanceMethods)
    end
  end

  module InstanceMethods
    def extension_one
      $stderr.puts(Rails.logger.debug("==== extension_one"))
    end
  end
end

ActiveRecord::Base.send(:include, MyExtensions)
=== EOF

Don''t stick things at the bottom of environment.rb - when class
caching is turned on, rails will load models before you get there.
Stuff like this belongs in an initializer.

I''m just now realizing how environment.rb has changed in Rails3.  Next 
question: where does one learn the zen of initializers?  Do I create my 
own, e.g. $ROOT/config/initializers/my_extensions.rb?  And is it 
stylistically correct to stick something like "require
''my_extensions''"
in an initializer file?

Thanks.

FWIW, I simply created a $ROOT/config/initializers/my_extensions.rb file 
and populated it with:

  require ''my_extensions''

... and rspec is all happy.  Let me know if that''s not the right way to
go.  Thanks for getting me pointed in the right direction.
