这是我的meccano，它是用周围的一些碎片做成的。这段代码来自我的一个未完成和废弃的项目，但它起到了作用（在我个人记忆中）。
注意，我在元名称前面加了下划线(_tie_post_views) 避免其出现在编辑后页面的自定义字段元框中。
您将被迫使用字段定位玩一段时间（可能使用JavaScript？）因为快速编辑和批量编辑实现存在缺陷。
很抱歉，我现在无法描述和评论该代码，但有一天我会尝试回答相关问题。而且，它看起来几乎不言自明。

以及
tie-bulk-quick-edit.js （应完全重写，但它将继续）：
jQuery(document).ready(function($){

inlineEditPost.edit = function(id){
$inline_editor.apply(this, arguments);
var post_id = 0;
