レコードが作成/更新されるたびにメソッドを実行しようとしています。
私は両方を試してみましたがafter_touch、around_saveどちらも新しい記録を作成するために機能しませんでした。
実際around_save、レコードが編集されている場合は機能しません。
レコードが保存されるたびに (作成時または編集/更新されるたびに) レコードを更新するために使用できるコールバックは何ですか?

ここにいくつかのコードがあります：
after_save :set_firm_size, :if => Proc.new { |c| c.firm.present? }
after_save :set_score
after_save :check_or_set_max
after_save :calculate_weighted_score, :if => Proc.new { |c| c.score.present? }
実行されていないコールバックは最後のものcalculate_weighted_scoreです。
def calculate_weighted_score
# Sum products of weight & scores of each attribute
weight = Weight.first
score = self.score
self.weighted_score = (weight.firm_size * score.firm_size) + (weight.priority_level * score.priority_level) +
(weight.inflection_point * score.inflection_point) + (weight.personal_priority * score.personal_priority) +
(weight.sales_priority * score.sales_priority) + (weight.sales_team_priority * score.sales_team_priority) +
(weight.days_since_contact * score.days_since_contact) + (weight.does_client_vote * score.does_client_vote) +
(weight.did_client_vote_for_us * score.did_client_vote_for_us) + (weight.days_until_next_vote * score.days_until_next_vote) +
(weight.does_client_vote_ii * score.does_client_vote_ii) + (weight.did_client_vote_ii_for_us * score.did_client_vote_ii_for_us) +
(weight.days_until_vote_ii * score.days_until_vote_ii)
# self.update_attributes(:weighted_score => weighted_score)
end

client.weighted_score表示されるのは、更新されるがログには表示されないステートメントであることに注意してください。
追加するself.update_attributes...と、stack is too deep error. self.saveの代わりに追加した場合も同じことが起こりself.update_attributesます。
