    subtype_id = fields.Many2one(default=lambda self: self.sudo().env.ref('mail.mt_comment', raise_if_not_found=False).id)
AttributeError: 'NoneType' object has no attribute 'id'

I do not know how to fix this error, I've tried everything So I'm seeing this error is in the mail module, which is in the addons folder

Answer 1

odoo 11 error when installing module subtype_id Hello, I tried to install the module which you have been made.This gave the error of "ImportError: No module named 'models'" . So you have to write in init .py file like this....

from . import models this will solved your error.

you ask about an error in mail module this is caused by your another custom module in your path. there is no other error in this module.so check your other custom modules.

Answer 2

Try this:

In your /__init__.py , import all python files in the models folder by

from . import models

Then in /models/__init__.py import your custom_model.py file by

from . import custom_model

Every time you add new file in models folder, you have to add it in your /models/__init__.py file.
