Need to replace original function of odoo 9 pos module with my own one. Never did it before so studied manuals and samples first but still no success.

Original code in screens.js is the following:


var PosBaseWidget = require('point_of_sale.BaseWidget');
var gui = require('point_of_sale.gui');
var models = require('point_of_sale.models');
var core = require('web.core');
var Model = require('web.DataModel');
var utils = require('web.utils');
var formats = require('web.formats');
var QWeb = core.qweb;
var _t = core._t;
var round_pr = utils.round_precision;
/*--------------------------------------*\
 | THE SCREEN WIDGET |
\*======================================*/
// The screen widget is the base class inherited
var ScreenWidget = PosBaseWidget.extend({
 init: function(parent,options){
 this._super(parent,options);
 this.hidden = false;
 },
 barcode_product_screen: 'products', //if defined, this screen will be loaded when a product is scanned
 // what happens when a product is scanned : 
 // it will add the product to the order and go to barcode_product_screen. 
 barcode_product_action: function(code){
 var self = this;
 if (self.pos.scan_product(code)) {
 if (self.barcode_product_screen) {
 self.gui.show_screen(self.barcode_product_screen);
 }
 } else {
 this.barcode_error_action(code);
 }
 },
... etc ...

I'm doing the following thing:

openerp.my_pos = function (instance) {
 module = instance.point_of_sale;
 var QWeb = instance.web.qweb;
 var _t = instance.web._t;
 var gui = require('point_of_sale.gui');
 var models = require('point_of_sale.models');
 var core = require('web.core');
 var Model = require('web.DataModel');
 var utils = require('web.utils');
 var formats = require('web.formats');
 module.ScreenWidget.prototype.barcode_product_action = function (code) {
 var show_code;
 if (code.code.length > 32) {
 show_code = code.code.substring(0, 29) + '...';
 } else {
 show_code = code.code;
 }
 this.gui.show_popup('error-barcode', show_code);
 };
};

But it does not affect behavior.

Below is my xml file I'm inserting my code with:


<?xml version="1.0" encoding="utf-8"?>
<openerp>
 <data>
 <template id="assets_backend" name="pos assets" inherit_id="point_of_sale.assets_backend">
 <xpath expr="." position="inside">
 <script type="text/javascript" src="/mopnex_erp/static/src/js/my_pos.js"></script>
 </xpath>
 </template>
 </data>
</openerp>

Solved finally. Below is the code (v9)


odoo.define('my_pos.my_pos', function (require) {
 "use strict";
 var screens = require('point_of_sale.screens');

 screens.ScreenWidget.include({
 barcode_product_action: function (code) {
 var show_code;
 if (code.code.length > 32) {
 show_code = code.code.substring(0, 29) + '...';
 } else {
 show_code = code.code;
 }
 this.gui.show_popup('error-barcode', show_code);
 },
 });
});

I have tried something like that but I got this error:

"Missing dependencies: ["account.account_payment_widget"] " at the line :

var payment = require('account.account_payment_widget');

    	validate_order: function=||var=this(options) {
    		options  options  {}; 
           
            
            // Write your code here

var round_di = instance.web.round_decimals;

var round_pr = instance.web.round_precision

var orderline_id = 1;

module.Orderline = Backbone.Model.extend({

initialize: function (attr, options) {

this.discount = 0;

this.discountStr = '0';

this.type = 'unit';

this.selected = false;

this.id = orderline_id++;},

set_discount: function (discount) {

//var disc = Math.min(Math.max(parseFloat(discount) || 0, 0), 100);

You can overload this function just like it is done in the code above. Find the proper module and widget, find the function, use "include" or "extend" to add your own code, do not forget to call the original one with "_super" or "prototype".
