嗨，我有一个表格，我想显示嵌套表格以添加问题并根据表格给出的答案更新比率星
<%= form_for @interview_round do |f| %>

我实际上是在 interview_rounds 控制器的编辑表单中使用它
嵌套形式的方法为
def edit
@interview_round = InterviewRound.where(id: params[:id]).first
3.times {@interview_round.round_questions.build}
respond_to do |format|
format.js
end
end
interview_rounds 模型
has_many :round_questions
accepts_nested_attributes_for :round_questions
和 round_question 模型
belongs_to :interview_round
评分系统实际上定义为，当用户对逻辑技能、沟通技能和技术技能（分数来自问答）进行评分时，会计算星级的平均值并将其存储在整体技能和此功能的 javascript 中给出为
$('#star-log').raty({
target : '#hint-log',
targetType : 'score',
targetKeep : true
});
$('#star-comm').raty({
target : '#hint-comm',
targetType : 'score',
targetKeep : true
});
$('#star-tech').raty({
target : '#hint-tech',
targetType : 'score',
targetKeep : true
});
$('#star-overall').raty({
target : '#hint-overall',
targetType : 'score',
targetKeep : true,
readOnly : true
});
$(document).on("click", ".stars", function(){
var score = 0 ;
//loop through stars to get score
$('.stars').each(function(i, obj) {
//if score is there will be undefined if star not selected
if ($(obj).raty('score'))
score += $(obj).raty('score');
});
//calculating average
score = score / $(".stars").length;
$('#star-overall').raty({score: score });
$("#hint-overall").val(score.toFixed(2));
});
现在功能定义为
表格上已经存在 3 个问题，并且会有一个添加更多可选问题的按钮（3 个问题是强制性的），当用户对问题进行评分时，这些问题的答案将是星级类型，分数将被计算并作为平均率存储在技术技能中（技术技能对整体技能的贡献）
请告诉我如何提供添加更多问题的选项，这些答案评分将被计算为平均水平并存储在技术技能中，我正在研究它一天但不知道该怎么做，提前谢谢
