I have inherit res.partner and added a field named: rel_zone = fields.Integer(compute="_getzone", string='Zone', readonly=False)
In _getzone there is a lookup regarding country, zipcode = postal zone.
In my custom module I'm referring to
customer_id = fields.Many2one('res.partner', String="Customer")
zone = fields.Integer(string="Zone code", related='customer_id.rel_zone', store=True, readonly=True)
I'm getting the error:
File "C:\Bitnami\odoo-12\apps\odoo\Lib\site-packages\odoo-12.0.post20200815-py3.7.egg\odoo\fields.py", line 547, in _setup_related_full field = target._fields[name] KeyError: 'rel_zone'Can anyone tell me why I'm getting this error
Thanks in advanced
