odoo为什么没人用

基于odoo开发的系统已经给公司用户使用了。在用户使用体验层面，最吐槽的就是odoo的过滤器，用起来不方便。当然这个过滤器也是有它自身的优点的，比如支持自定义查询字段，丰富的查询过滤条件，对常用查询进行保存等。吐槽的地方是如果设置多个查询字段的话，操作不方便。
下图是筛选器的操作界面：
图一
下图是点击应用后的界面: 图二

如上，对已添加的查询字段只支持删除或恢复操作，修改查询条件或者修改查询内容的话只能再添加新的查询字段来完成。比如，我想修改查询币种为美元的话，需要这么操作才可以。

而且每次修改的时候都会自动触发后台的数据查询。实际的用户使用方式可能是修改了多个查询的内容，才需再次查询。
为此我们对筛选器做了体验升级处理，先给出最终的效果：

上面的这种操作体验方式是不是更合理方便啊，呵呵。

想要实现上面的效果，肯定就要对odoo的前端代码进行改造了。对于开发来说，改造有两种方法：要么直接修改源代码，要么通过扩展继承的方式来改。幸好odoo前端提供了include及extend的两种扩展集成方式，改起来就方便多了，而且是一种插件的方式，对原代码没有任何的侵入。

代码基于odoo13版本，整个改造过程分为以下几步：

1、自定义QWEB的templates文件，实现查询字段的行显示模式以及增加查询按钮

<?xml version="1.0" encoding="UTF-8"?>

<templates xml:space="preserve">
    <div  class="dropdown" t-name="web.DropdownMenu.custom" t-att-class="widget.dropdownStyle.el.class" t-att="widget.dropdownStyle.el.attrs">

2、QWEB元素的js渲染处理
