odoo14在tree、kanban视图上添加dashboard

效果图：

实现代码：js：view的类型原来1个js给拆分成了4个： view, controller, renderer, model

1、view：AbstractView的子类，这是工厂类：类需要解析 arch字段并设置其它3个类

2、Renderer ：渲染器，来自 AbstractRenderer：负责在用户界面中展示数据；

3、Controller：一个控制器 (来看AbstractController)：用于协调、与网页客户端对话

4、Model：一个模型 (来自 AbstractModel)：用于和服务端对话、加载数据并处理数据

步骤：一、二、三、四案例

一、MVCR：

var MapController = AbstractController.extend({});
var MapRenderer = AbstractRenderer.extend({});
var MapModel = AbstractModel.extend({});

var MapView = AbstractView.extend({
　　config: {
　　　　Model: MapModel,
　　　　Controller: MapController,
　　　　Renderer: MapRenderer,
　　},
});

二、告知网页客户端视图名称和实际类之间的映射。
var viewRegistry = require('web.view_registry');
viewRegistry.add('helpdesk_dashboard', HelpdeskDashboardView);

三、现在我们需要告知网页客户端指定的 ir.ui.view需要使用我们的新类。注意这是一个网页客户端的具体考虑。

从服务端的视角来看，我们还是对应看板视图。这么做的相应方式是通过对框架的根节点使用特殊属性js_class

<record id="helpdesk_team_view_kanban" model="ir.ui.view" >
...
　　<field name="arch" type="xml">
　　<kanban js_class="helpdesk_dashboard">
...
</kanban>
</field>
</record>

案例：

odoo.define('purchase.dashboard', function (require) {
"use strict";

/**
 * This file defines the Purchase Dashboard view (alongside its renderer, model
 * and controller). This Dashboard is added to the top of list and kanban Purchase
 * views, it extends both views with essentially the same code except for
 * _onDashboardActionClicked function so we can apply filters without changing our
 * current view.
