Odoo-12：我创建了一个小部件。 我如何使用它？

Question

I created a custom module that defines a widget. here are the .js file as well as the QWeb template:

bh_sidebar.js

odoo.define('sidebar_widget.bh_sidebar', function (require) {
    'use strict';
    var Widget = require('web.Widget');
    var widgetRegistry = require('web.widget_registry');
    var core = require('web.core');

    var QWeb = core.qweb;
    var _t = core._t;

    var bh_sidebar = Widget.extend({
        init: function () {
            var self = this;
            this._super(parent);
            console.log('Widget initialized!');
        },

        events: {},

        start: function () {
            this.$el.append(QWeb.render('bh_sidebar_template'));
            console.log('Widget started!');
        }

    });

    widgetRegistry.add(
        'bh_sidebar', bh_sidebar
    )
})

bh_sidebar.xml

<?xml version="1.0"?>
<templates id="template" xml:space="preserve">
    <t t-name="bh_sidebar_template">
        <div style="background-color:red;" class="myClass">
            <a href="#" class="butt1">Button 1</a>
            <a href="#" class="butt2">Button 2</a>
        </div>
    </t>
</templates> 

I've added both to the backend assets using:

<odoo>
    <data>
        <template id="assets_backend" inherit_id="web.assets_backend">
            <xpath expr="script[last()]" position="after">
                <script type="text/javascript" src="/sidebar_widget/static/src/js/bh_sidebar.js"></script>
                <!-- <script type="text/javascript" src="/sidebar_widget/static/src/js/renderer.js"></script> -->
                <link rel="stylesheet" type="text/scss" href="/sidebar_widget/static/src/scss/widget.scss"></link>
            </xpath>
        </template>
    </data>
</odoo>

I've also added the templates to the manifest file.

This widget is supposed to display a red rectangle with two links, button 1 and button 2. I want this widget to be independent of any type of view, and just show up at the top of the screen beneath Odoo's navigation bar. How do I that? if I try to run my code as is, nothing happens. I've been at this for a week. Nothing I found on the internet helped. The documentation is criminally outdated, the ressources scarce.

I would appreciate any help. Thank you.

Your widget will not be instantiated and inserted into the DOM automatically. To do this, you can hook into any of the already existing high-level widgets. For example, using the show_application method on the WebClient:

var WebClient = require('web.WebClient');

WebClient.include({

    show_application: function () {
        var sup = this._super.apply(this, arguments);

        // Instantiate
        var sidebar = new bh_sidebar();

        // Insert in DOM
        sidebar.insertAfter(this.$('.o_main'));

        return sup;
    },

});

我认为你应该通过使用控制器机制来呈现这个视图，这将使这个视图独立于其他视图。
