Question

I'm trying to add discussions and notifications to academy class but got error. My code: models.py

class Courses(models.Model):
_name = 'academy.courses'
_inherit = 'mail.thread'

views.xml

<div class="oe_chatter">
  <field name="message_follower_ids" widget="mail_followers"/>
  <field name="message_ids" widget="mail_thread"/>
</div>

openerp.py

'depends': ['website'],

What do I tried:

openerp.py

'depends': ['website', 'mail'],
then:

models.py

class Courses(models.Model): _name = 'academy.courses' _inherits = ['academy.courses', 'mail.thread']

But nothing helps :(

I might sound silly but i gonna ask anyway, have you tried to restart the server? — SDBot
I got the same error. I think odoo haven't mentioned it in their tutorial.odoo.com/documentation/10.0/howtos/website.html. Thank you for your answer. :) — Christo Jose

Thank you for the answers. I think I found a solution.

For me helps in __openerp__.py in depends change website -> base. I don't know why but it helps. Maybe anyone knows why?

depends': ['base', 'mail']

Odoo _inherit = 'mail.thread' error
