odoo14在列表视图里添加自定义按钮

static/js/xxxx.js   这里定义按钮

odoo.define('add.tree.view.buttons', function (require) {
"use strict";
    var core = require('web.core');
    var ListController = require('web.ListController');
    var ListView = require('web.ListView');
    var viewRegistry = require('web.view_registry');

    var qweb = core.qweb;

    var AddListViewController = ListController.extend({
        buttons_template: 'AddsListView.buttons',
        /**
         * Extends the renderButtons function of ListView by adding an event listener
         * on the bill upload button.
         *
         * @override
         */
        renderButtons: function () {
            this._super.apply(this, arguments); // Possibly sets this.$buttons
            if (this.$buttons) {
                var self = this;
                this.$buttons.on('click', '.o_button_add_tree_btn', function () {
                    var actived_ids = [];
                    var select_value = $('tbody .o_list_record_selector input');
                    var state = self.model.get(self.handle, {raw: true});
                    //这里是获取列表中选中的record
                    for (var i=0;i<select_value.length;i++){  
                       if (select_value[i].checked===true){       
                            actived_ids.push(state.res_ids[i]);   
                        }                
                    }
                    self.do_action({
                        type: 'ir.actions.act_window',
                        res_model: 'test.wizard',//向导模型
                        target: 'new',
                        views: [[false, 'form']],
                        context: {active_ids:actived_ids},
                    });
                });
            }
        }
    });

    //注册你的插件
    var AddsListView = ListView.extend({
        config: _.extend({}, ListView.prototype.config, {
            Controller: AddListViewController,
        }),
    });

    viewRegistry.add('add_buttons_tree', AddsListView);
});

这里添加按钮：static/xml/xxxx.xml

<?xml version="1.0" encoding="UTF-8"?>
<templates>
    <t t-extend="ListView.buttons" t-name="AddsListView.buttons">
        <t t-jquery="button.o_button_import" t-operation="replace"></t><！--隐藏列表导入按钮-->

 <t t-jquery="button.o_list_button_add" t-operation="after"> <！--将新加按钮放置创建按钮后面--> <button type="button" class="btn btn-danger o_button_add_tree_btn" title="按钮1">按钮1</button> </t> </t> </templates>

导入你的js

<odoo>
    <data>
        <template id="assets_backend" name="add list buttons" inherit_id = "web.assets_backend">
            <xpath expr="." position="inside">
                <script type="text/javascript" src="/mde_name/static/src/js/add_tree_view_button.js"></script>
            </xpath>
        </template>
    </data>
</odoo>

最后在列表视图中引用：js_class="AAAAAAAAA"

    <tree string="" js_class="add_buttons_tree" delete="0" >
