Hi

By default, One2many fields changes won't update on chatter.


To display tracking of the One2many field in chatter, please refer to the code below.


class A(models.Model):
_name = "A.A"
_inherit = ['mail.thread', 'mail.activity.mixin']

name = fields.Char("Name")
b_lines = fields.One2many('B.B', 'a_id')


class B(models.Model):
_name = "B.B"
_inherit = ['mail.thread', 'mail.activity.mixin']

a_id = fields.Many2one('A.A')
name = fields.Char("Name",tracking=True)
#To Show tracking in chatter Add tracking=True

def write(self, vals):
super().write(vals)
if set(vals) & set(self._get_tracked_fields(vals)):
self._track_changes(self.a_id)

def _track_changes(self, field_to_track):
if self.message_ids:
message_id = field_to_track.message_post(
body=f'{self._description}: {self.display_name}').id
trackings = self.env['mail.tracking.value'].sudo().search(
[('mail_message_id', '=', self.message_ids[0].id)])
for tracking in trackings:
tracking.copy({'mail_message_id': message_id})


Hope it helps,

It works !!

But you forgot to return the super() of the write method.

HI,

Try to inherit "mail.thread" Model in your line model. Try to add _inherit = ['mail.thread'] line after your model description.

Just like this:

class YourCustomModel(models.Model):
_name = 'your.custom.model.name'
_inherit = ['mail.thread']
_description = 'Your Custom Model'

Hope it will help you.
