Hi all,

Can some help to setup communication between server and client, where I want to update the standard progresBarField in real-time:

/** @odoo-module **/

import { registry } from "@web/core/registry";

import { patch } from "@web/core/utils/patch";

import { ProgressBarField } from "@web/views/fields/progress_bar/progress_bar_field";

const fieldRegistry = registry.category("fields");

console.log("Progress listener setup");

patch(ProgressBarField.prototype, {

    setup() {

        super.setup();

        console.log("Setup progress bar");

        this.busService = this.env.services.bus_service;

        console.log("busService active is %B", this.busService.isActive);

        this.channel = "progress_bar_channel";

        this.busService.addChannel(this.channel);

        this.busService.addEventListener("notification", this.onBusMessage.bind(this));

    },

    onBusMessage({detail: notifications}) {

        console.log("onBusMessage", notifications);

        notifications = notifications.filter(item => item.type === 'notification')

        notifications.forEach(item => {

           console.log("Progress: %d on field %s", item.payload.progress, item.payload.field);

           this.setProgress(item.payload.field, item.payload.progress);

        })

    }, 

    setProgress(fieldName,newProgress) {

        if (newProgress >= 0 && newProgress <= 100) { // Ensure the progress is within bounds

            console.log("newProgress", newProgress);

            let value = String(newProgress);

            this.onValueChange(value, fieldName);

       }

    }

});  

At the Odoo server side I send progress information from a Model in Python as follows:

class MyImportWizard(models.TransientModel):

    _name = 'myapp.import.wizard'

    _description = 'Import Wizard '

    _inherit = ['bus.listener.mixin'] # Inherit the mixin for bus notifications

    file = fields.Binary("Select File", required=True, file_name = fields.Char()

    progress = fields.Integer(string="Progress", default=0)   

    def import_file(self):

        records = self.env['myapp.data'].search([])

        rows_to_process = records.__len__()

        rows_processed = 0

        for record in records:

            .... # Do some model and other model and database update work

            rows_processed = rows_processed + 1

            self.progress = (int)((rows_processed * 100) / rows_to_process)

            self.env['bus.bus']._sendone('progress_bar_channel', 'notification',

                                             {'field': 'progress','progress': self.progress})                                                       

            self.env.cr.commit(). # Needed in Odoo 17 to release (send) bus messages to the client

        self.progress = 100 # Complete the task

        self.env['bus.bus']._sendone('progress_bar_channel', 'notification',

                                             {'field': 'progress', 'progress': self.progress})

What changed in Odoo 18, that this is not working anymore. I see a lot of guessing work and changes over the different Odoo versions, where the Bus (bus.bus) API changed from version to version. In Odoo 17 I see all the console messages in the browser. In both Odoo 17 and 18 the bus_service is seen as active.

Can someone provide a good and working example on how this should work for Odoo 18 

Thanks for your help and I hope that the answer contributes to a better Odoo
