Guys, I need to change the "make_message" function in the chat_manager.js file in the mail module.

Basically, I want to add a new field to the ouput of the function.

How can I do this? I've build a module that does everything well up until the moment I need to change javascript.

odoo.define('MYMODULE.chat_manager', function (require) {

"use strict";

    var mail_chatter_manager = require('mail.chat_manager');

    mail_chatter_manager.include({

        make_message: function make_message (data) {

            var msg = {

                id: data.id,

                author_id: data.author_id,

                body: data.body || "",

                date: moment(time.str_to_datetime(data.date)),

                message_type: data.message_type,

                subtype_description: data.subtype_description,

                is_author: data.author_id && data.author_id[0] === session.partner_id,

                is_note: data.is_note,

                is_system_notification: (data.message_type === 'notification' && data.model === 'mail.channel')

                    || data.info === 'transient_message',

                attachment_ids: data.attachment_ids || [],

                subject: data.subject,

                email_from: data.email_from,

                customer_email_status: data.customer_email_status,

                customer_email_data: data.customer_email_data,

                record_name: data.record_name,

                tracking_value_ids: data.tracking_value_ids,

                channel_ids: data.channel_ids,

                model: data.model,

                res_id: data.res_id,

                url: session.url("/mail/view?message_id=" + data.id),

                module_icon:data.module_icon,

                read_by: data.read_by,

            };

            //Etc., etc., etc.

        },

    });

});

I always get a "mail_chatter_manager.include is not a function" error.

A whole module (that could well go public for free is dependent on this!)
