限制 POS Odoo 17 中的缺货产品

Question

我有这个代码，如果缺货，则限制 POS 上的产品销售。但当我选择产品然后单击付款按钮时它就起作用了。当我点击 POS 会话上的付款按钮时，它将显示一条关于缺货产品的消息。我想添加另一个功能，我希望当我点击缺货产品时显示此消息。例如，如果产品缺货，当我点击该产品时，它应该给我警告消息。无法选择缺货产品。因此，我不想选择缺货的产品，然后在付款时显示消息，而是想在选择产品时显示消息。任何人都可以帮助我使代码适用于 odoo 17。我是 Odoo POS 开发的新手。请帮帮我，谢谢。

我如何为 odoo 17 制作这个？

我尝试过搜索此问题，但没有得到任何解决方案

首先，您应该在模块资产中指定它，如下所示。

    'point_of_sale._assets_pos': [
        'your_module_name/static/src/js/your_js_filename.js'
    ],

然后，您的 JavaScript 代码必须如下所示：Odoo 在 16 和 17 上更新了其资产目录，因此请确保您的资产如下所示列出。

/** @odoo-module */

import { Order } from "@point_of_sale/app/store/models";
import { patch } from "@web/core/utils/patch";

        let lines = order.get_orderlines();

        let config_id = this.env.services.pos.config.id;
        let prod_used_qty = {};
        let outOfStockProducts = [];
        let restrict = false;
        if (pos_config.restrict_zero_qty) {
            lines.forEach(line => {
                let prd = line.product;
                if (prd.type === 'product') {
                    if (prd.id in prod_used_qty) {
