How to use Chatter in 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.

2. 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.

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.
