Rails - Aug 2005 - join table attributes question

Hi all,

I''m having trouble updating the attributes of a join table
that''s used
in a habtm relationship. I can create new entries with
#push_with_attributes, but no matter what I do, I can''t seem to
generate
an sql UPDATE on the join table.

In my model, goats assign scores to boats. I have a join table called
"scores"
consisting of (goat_id, boat_id, score) tuples.

I have:

class Goat
  has_and_belongs_to_many :scores, :join_table => "scores",
:class_name => "Boat"

  def set_score_for boat, value
    i = scores.index boat
    if i.nil?
      scores.push_with_attributes boat, :score => value
    else
      scores[i].score = value # doesn''t seem to do anything
      boat.save # nope
      save # nope
    end
  end
end

Am I missing something obvious?

Thanks for any help,
