我想为我刚刚通过 .ajax() 回调创建的对象返回 JSON 数据,但它一直返回未定义,这让我相信我在创建操作中做错了什么。这里是:

def create 

    ajax_title = params[:title]
  ajax_content = params[:content]
  ajax_folder = params[:folder_id]
  ajax_parent = params[:parent_id]
  ajax_children = Array(params[:children])

  @submission = Submission.find_by_title(ajax_title)

  if ajax_title && @submission
      @submission.content = ajax_content
      @submission.save
  else
      @submission = Submission.create(
          :title=>ajax_title,
          :content=>ajax_content, 
          :user_id=>current_user.id, 
          :folder_id=>ajax_folder,
          :parent_id=>ajax_parent, 
          :children=>ajax_children,
      )
  end

respond_to do |format|
  if @submission.save
    format.json { render :json => @submission.to_json }
  else
    format.json { :errors => @submission.errors }
  end
end

end

在底部,您会看到我尝试渲染它的位置。这是我的 AJAX PUT 请求:

entryAJAX = function(){
  $("#entry-button").click(function(){
    $.ajax({
    url: "/submissions",
    type: "POST",
    dataType: "json",
    data: {folder_id: <%= @folder.id %>},
    complete: function(data){
    console.log(data.id);         
      }
            });
  });      
};

我知道路线并创建操作,因为模型实例已成功创建,所以知道为什么数据返回未定义?
