RubyonRails——javascript没有'；行不通

我需要实施星级评定系统，让

用户

评定

酒店

。我举了一个例子

rating.js文件是：

$(function() {
  $('.rating_star').click(function() {
    var star = $(this);
    var form_id = star.attr("data-form-id");
    var stars = star.attr("data-stars");
    $('#' + form_id + '_stars').val(stars);

    $.ajax({
      type: "post",
      url: $('#' + form_id).attr('action') + '.json',
      data: $('#' + form_id).serialize(),
      success: function(response){
        console.log(response);
        update_stars();
        if(response["avg_rating"]){
          $('#average_rating').text(response["avg_rating"]);
          }
        }
      })
  });        
});

function update_stars(){
  $('.star_rating_form').each(function() {
    var form_id = $(this).attr('id');
    set_stars(form_id, $('#' + form_id + '_stars').val());
  });
}

function set_stars(form_id, stars) {
  for(i = 1; i <= 5; i++){
    if(i <= stars){
      $('#' + form_id + '_' + i).addClass("on");
    } else {
      $('#' + form_id + '_' + i).removeClass("on");
    }
  }
}

带有评级星的页面来源包括以下行：

UPD1:rails错误日志的输出显示我错过了

end

语句。。。添加后，错误发生了变化：

下一行中的控制器中出现错误：

@rating.update_attributes(params[:rating])

---

您收到的错误表明您错过了文件末尾的

end

语句

这很可能是因为缩进错误，可能导致了不平衡的

end

语句

以下是文件的结尾：

  def js_logged_in
    if(!signed_in?)
    flash[:error] = "You must be a signed in to leave a rating!"
    render :js => "window.location = '/signin'"
  end
end

---

最后的

end

不会关闭类定义，它会关闭

def js_logged_in

方法。如果没有缩进

if

，那么与

def js\u logged\u匹配的
end
实际上是在关闭
if
你所说的“我认为错误完全在java代码中”是什么意思？浏览器控制台的输出是什么？有JS错误吗？对不起，我是说“某处”。不，控制台中没有错误。能否显示此错误的控制台日志？抱歉，我不清楚。运行错误日志就是我的意思。基本上是终端窗口，当您单击星型时，您会在其中写入“rails服务器”，您会得到一个内部服务器错误。如果有错误，请告诉我们log@AlMacks请粘贴有问题的整个输出。您是对的，但现在有一个新错误（在我添加了“end”之后）。UPD…当我将行更改为@rating.update_attributes（rating_params）时，它就消失了。非常感谢。
  def js_logged_in
    if(!signed_in?)
    flash[:error] = "You must be a signed in to leave a rating!"
    render :js => "window.location = '/signin'"
  end
