Odoo PoS not showing custom field value

Question

I´ve created a module that adds some custom fields to the res.partner model and the PoS partner with a python file and a javascript file. I know both are working correctly because when I write some content in the field, the record is updated in the backend. The problem is that the PoS doesn´t show the field value. The python file that adds the field have the following form:

# -*- coding: utf-8 -*-

from odoo import models, fields, api

class MyModulePartner(models.Model):
    _inherit = 'res.partner'

    billing_name = fields.Char(string='Billing name')
    billing_number = fields.Char(string='Billing number')

The javascript file has the next form:

odoo.define('my_module.partner', function (require) {
"use strict";

   var models = require('point_of_sale.models');
   var _super_posmodel = models.PosModel.prototype;

   models.PosModel = models.PosModel.extend({
   initialize: function (session, attributes) {
      var partner_model = _.find(this.models, function(model) {
           return model.model === 'res.partner';
      });
      partner_model.fields.push(['billing_name', 'billing_number']);
      return _super_posmodel.initialize.call(this, session, attributes);
      },
   });
});

Then I added the javascript file with the file "views/computerized_pos_assets_template.xml" with the following code:

<?xml version="1.0" encoding="utf-8"?>
<odoo>

   <template id="assets" inherit_id="point_of_sale.assets">
      <xpath expr="." position="inside">
         <script type="text/javascript" src="https://stackoverflow.com/my_module/static/src/js/partner.js"></script>
      </xpath>
   </template>

</odoo>

Tried to change the pos view with the file "static/src/xml/computerized_pos.xml" with the following code:

<?xml version="1.0" encoding="UTF-8"?>
<template xml:space="preserve">

    <t t-extend="ClientDetailsEdit">
        <t t-jquery=".client-details-left" t-operation="replace">

                    <input class='detail client-billing-name'           name='billing_name'     t-att-value='partner.billing_name || ""'></input>
                </div>
                <div class='client-detail'>

                    <input class='detail client-email'  name='email'    type='email'    t-att-value='partner.email || ""'></input>
                </div>
            </div>
        </t>
   </t>

<t t-extend="ClientDetails">
        <t t-jquery=".client-details-left" t-operation="replace">
            <div class='client-details-left'>

                    <t t-if='!partner.billing_name'>
                        <span class="detail client-billing-name empty">N/A</span>
                    </t>
                </div>
                <div class='client-detail'>
                    <span class='label'>Barcode</span>
                    <t t-if='partner.barcode'>
                        <span class='detail client-id'><t t-esc='partner.barcode'/></span>
                    </t>
                    <t t-if='!partner.barcode'>
                        <span class='detail client-id empty'>N/A</span>
                    </t>
                </div>
                <div class='client-detail'>
                    <span class='label'>Correo</span>
                    <t t-if='partner.email'>
                        <span class='detail client-email'><t t-esc='partner.email' /></span>
                    </t>
                    <t t-if='!partner.email'>
                        <span class='detail client-email empty'>N/A</span>
                    </t>
                </div>
            </div>
        </t>
   </t>

And finally in the manifest file I´ve added the files like the following:

'data': [
        'views/computerized_pos_assets_template.xml',
    ],
    'qweb': [
        'static/src/xml/computerized_pos.xml',
    ],

Something that I´ve noticed is that when in the "views/computerized_pos_assets_template.xml" I detail the javascript file location like "/my_module/static/src/js/partner.js" Odoo throws the following error:

Traceback (most recent call last):

  File "/opt/odoo/odoo13/odoo/models.py", line 2800, in valid
    field = self._fields.get(fname)
TypeError: unhashable type: 'list'

But when the location is "/static/src/js/partner.js" I get the following error:

point_of_sale.assets.js:477 Could not get content for /static/src/js/partner.js defined in bundle 'point_of_sale.assets'.

Try to load fields like this :- models.load_fields("res.partner", ["billing_name", "document_number"]); — Vishnu VaNnErI

I´ve realized that the function I used to push fields doesn´t support lists, so after I corrected the js file like the following, the field worked correcly:

odoo.define('kyohei_pos_computerized_billing.partner', function (require) {
    "use strict";

    var models = require('point_of_sale.models');
    var super_posmodel = models.PosModel.prototype;

    models.PosModel = models.PosModel.extend({
        initialize: function (session, attributes) {
            var partner_model = _.find(this.models, function (model){
                return model.model === 'res.partner';
            });
            partner_model.fields.push('billing_name');
            return super_posmodel.initialize.call(this, session, attributes);
        },
    });
});

What version of Odoo is this and would this work for version 14?

Simon Capriles Over a year ago

This used to work on Odoo 13. In Odoo 14 OWL appeared and this doesn´t work.

It actually still works, you're a lifesaver! Would you by any chance know how I can automatically append a product to the orderline and set a custom price on the appended product (on click of like a custom button)
