I'm trying to add a relational field to a model entity ( Odoo 11 ). I have two classes

 
# -*- coding: utf-8 -*-
from odoo import models, fields, api
class Cantiere(models.Model):
    _name = 'modulotest01.cantiere	
    name = fields.Char(required=True)
    description = fields.Text()
    direttore = fields.Many2one('modulotest01.direttore', string='Direttore',index=True,ondelete='cascade'
class Direttore(models.Model):
    _name = 'modulotest01.direttore'
    name = fields.Char(required=True)
    start_date = fields.Date(
    #cantiere_id = fields.One2Many('modulotest01.cantiere', 'direttore_id'


Obviously this code doesn't work and i don't know why

Hai Alessandro Losco

in the first class Cantiere, you define a "Many2one" field. and the second class direttore, you define a One2many (You use a wrong key word #One2Many). In this One2many you need use the field direttore(Many2one). But you use "direttore_id"
cantiere_id = fields.One2many('modulotest01.cantiere', 'direttore')

Try to correct these issues, and make the relation.
If you have any doubt free to contact.
Thank you,
