How to use Chatter in Odoo? - odoo

Question

I want to use Chatter for students model, so that, when value of some field is changed then it is logged under student form
To achieve this, I did the following things:
1. Added this div
<div class="oe_chatter">
<field name="message_follower_ids" widget="mail_followers"/>
<field name="message_ids" widget="mail_thread"/>
</div>
in the student form.
It added the chatter, but when i clicked on New Message button, it gave the following error.
This could be because i haven't inherited mail.thread in student model.
Then i inherited this class in student model.
Then it again gave an error as shown below
I search this topic, but couldn't found anything.
It would be appreciated if someone could help me out.

Answer 1

In order to log changes of specific fields you need so set the track_visibility attribute on each field you want to track:
class OpStudent(models.Model):
_name = 'op.student'
_inherits = {
'res.partner': 'partner_id',
}
_inherit = [
'mail.thread',
'ir.needaction_mixin',
]
foo = fields.Char(track_visibility='always')
You may read more about it in the official documentation.

Answer 2

You're using Chatter for keeping the track on student details.
So I'll suggest another module which is working absolutely fine and keeps the track on student or any other model you want as I have personally used it.
I used audit log. It tracks all the CRUD operations. It will create Audit
the menu in setting tab from there you can set the model which you want to track.

Answer 3

I had the same problem, but with res.company, I solved it like this:
class ResCompany(models.Model):
_name = 'res.company'
_inherit = ['res.company','mail.thread', 'mail.activity.mixin']
date_end = fields.Date(string="Fin Date",tracking=True)
and in xml:
<xpath expr="//form/sheet" position="after">
<div class="oe_chatter">
<field name="message_follower_ids" widget="mail_followers"/>
<field name="message_ids" widget="mail_thread" />
</div>
</xpath>
I hope, that it serves you.
