Question

我在这里订阅了PubSub

ul.questions_list
 -if(@questions.empty?)
    |no questions available
 -else
   -@questions.each do|question|
     li 
       =link_to"#{ question.title } ", question_path(question)      

p= link_to 'Ask question', new_question_path
= subscribe_to '/questions'

然后去咖啡（在这种情况下，console.log提供正确的数据）

$ ->
  PrivatePub.subscribe '/questions', (data, channel) ->
    question = $.parseJSON(data['question'])
    console.log(question.title)
    $('.questions_list').append("<li><a href='/questions/#{question.id}'>#{question.title}</a></li>");

和控制器

  def create
    @question = Question.new(question_params)
    @question.user = current_user
    if @question.save
      PrivatePub.publish_to '/questions', question: @question.to_json
      redirect_to @question, notice: 'Your question successfully created.'
    else
      render :new
    end
  end

我收到了这样的错误

The connection to ws://localhost:9292/faye was interruped while the page was loading.
...et;t.exports={create:function(t){return **new** n(t)}}}).call(e.function(){return th...)

我不明白我做错了。非常感谢任何帮助
