How to Enable Field Tracking or track_visibility in Odoo

To enable tracking of fields you have to inherit the following models in your custom class or model.

class gym_body_parts_config(models.Model):

    _name = 'gym.body.parts.config'

    _inherit = ['mail.thread', 'mail.activity.mixin']

After inheriting the above models in your class, now just add this (tracking=True) attribute to the fields in which you want to track the record.

name = fields.Char(string="Name", required=True, tracking=True)

Now that we have implemented the tracking code in our model, now it's time to add some fields to views. Just add the below code in your XML after sheet tag.

<sheet>

<!--your form view fields goes here-->

</sheet>

<div class="oe_chatter">

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

<field name="activity_ids"/>

<field name="message_ids"/>

</div>

TypeError: Model 'your.model.name' inherits from non-existing model 'mail.thread'

If you are facing the above error then don't forget to add the "mail" module in the dependency (in the __manifest__.py file).
