Hi,

you can use notifications (add a notification when a new record for the object is created) at the bottom wall of an object , or associated to a field , what you have by example at the bottom of sale order form (log llist of created records, actions), button at the bottom right "Following" which list subtypes to check (all subtypes at menu settings/technical/email/subtypes), add user which can see notifications with button add user (all followers at menu settings/technical/email/followers), All notifications are stored in menu settings/technical/email/message, you can override search to add group by and filters you need.

But all objects have not notification available.

to have notification to add for an object :

inherit some necessary models with to your class:

_inherit = ['mail.thread', 'ir.needaction_mixin']

to display in form view, add at the end of xml definition of the form (between end of balise sheet and form) you can add a group if you do not want users see it:

</sheet>

<div class="oe_chatter">

<field name="message_follower_ids" widget="mail_followers" groups="base.group_user"/>

<field name="message_ids" widget="mail_thread"/>

</div>

</form>

to associate a subtype to a field, use _track, example:

_track = {

     'state': {

         'sale.mt_order_confirmed': lambda self, cr, uid, obj, ctx=None: obj.state in ['manual'],

         'sale.mt_order_sent': lambda self, cr, uid, obj, ctx=None: obj.state in ['sent']

         },

}

I believe it exists an attibute to add in a field definition in view, but can't remember it name ...

OR :

use module smile_log :

https://github.com/Smile-SA/odoo_addons

add menu settings/tecnichal/Logging

add in your python file :

import logging

override functions create, write, unlink for your class and add:

logger = SmileLogger(dbname, model_name, res_id, uid)

logger.info(your_message) # will create a log in db with a unique pid per logger

add group by and filters you need in search view

bye
