Имеется Odoo (OpenERP) 8.
Нужно добавить поле в sale.order

Вот так:

from openerp import models, fields

class SomeClass(models.Model):
    _inherit = 'sale.order'

    description = fields.Char(default="Some text")

На что odoo ругается следующим образом:

Меняем код, подтставляя другой модуль:

from openerp import models, fields

class SomeClass(models.Model):
    <strong>_inherit = 'res.partner'</strong>

    description = fields.Char(default="Some text")

И ошибки как не бывало.
Вопрос: это особенности 8й версии, или кривого кода, или и то и другое в совокупности?

Решение проблемы оказалось довольно простым: не забываем добавлять список зависимостей в __openerp__.py
В данном случае нужно было добавить зависимость от модуля «sale».
