Question

我正在尝试在创建/更新记录的任何时候执行方法。

我尝试了after_touch和around_save，但都没有用于创建新记录。

事实上，around_save在编辑记录时不起作用。

我可以使用什么回调来保存记录（包括创建时或编辑/更新时）？

以下是一些代码：

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? }

未执行的回调是最后一个calculate_weighted_score。

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

这是edit操作的日志：

请注意，您应该看到的是更新client.weighted_score但未显示在日志中的语句。

当我添加self.update_attributes...时，我得到了stack is too deep error。当我添加self.save而不是self.update_attributes时会发生同样的事情。

为什么`around_save`或`after_touch`回调不会在创建新记录时执行？
