Post a message on product form mail thread in odoo 11

Question

I want to post a custom message on the product form mail thread programmatically, i've inhereted the product.template module and here's my code

from odoo import models,fields,api

class product_sheet(models.Model):

_inherit = ['product.template']

fieldx = fields.Float()

@api.onchange('fieldx')
def post_msg(self):
    self.message_post(body="Write something here")

I don't want to use the track_visibility, I just need to write something in the thread programmatically, but I don't know how the message_post method works

what's the correct way of doing this?

Answer 1

Your code should work. What is the error that you are getting? Could you post the traceback.

Also you could try doing this in the write method, like this:

@api.multi
def write (self, values):
   res = super(YOURCLASS,self).write(values)
   if 'fieldx' in values:
       self.message_post(body="Write something")
   return res
