Problems with delegated inheritance of project module - Odoo 13

Question

I am inheriting the project.project model to add a "Project Type" field.

from odoo import models, fields, api

class Proyectos(models.Model):
     _name = 'girodapp.proyectos'
     _description = 'Proyectos potenciales de Girod'
     tipo_proyecto = fields.Selection([
        ('Global','Global'),
        ('Barreras y Verticales','Barreras y Verticales'),
        ('Pretiles','Pretiles'),    
        ])
     project.id = fields.Many2one(
        'project.project',
        delegate=True,
        ondelete='cascade',
        required=True)

but when installing the module I get the following error:

Error:
Odoo Server Error

NameError: name 'project' is not defined

According to the message the name project is not defined, but this same method I used with res.partner and it worked for me. What am I doing wrong? Help me Please!

Answer 1

Just change this to project.id to project_id.

The first syntax python will try to retrieve the attribute id from the object project this why he complains about it.

You are defining a Many2one one field so the name cannot have special characters. It is an identifier he must follow the rules that are in all programming language like it cannot start with number .... Etc
