how can I get the key of a many2one field in odoo 10

for example

color_id = fields.Many2one ('modelcolor', 'Cod.Colors')

cod_color=fields.char("cod.color")

where:

00-blue

01-red

@ api.onchange ('color_id)

      cod_color = self.color_id

I want the code of 00 or 01 to return, when the user selects a color.I need it to concatenate it with other data.

Hi,

The question seems to be not clear. If you are looking to get the value of the cod_color in the Many2one field of the modelcolor , you can change the rec_name of the corresponding model to the cod_color.

class ModelColor(models.Model):
    _inherit = "modelcolor"
    _rec_name = 'cod_color'


Or if you need to get the cod color value in the change of the color field, try below code, 

@api.onchange('color_id)
def change_color(self):
  self.cod_color = self.color_id.cod_color



Thanks

the code does not return any value, these are the models.

I wish that tcorr = tcod + A001

ex: tcorr = cod01 + A001

or tcorr = cod02 + A001, where cod01 (changes according to the field selection tdoc = many2one)

# -*- coding: utf-8 -*-
from odoo import _, api, fields, models

class einvoice_catalog_01(models.Model):
_name = "einvoice.catalog.01"
_description = 'Codigo de Tipo '

code = fields.Char(string='Codigo', size=4, index=True, required=True)
name = fields.Char(string='Descripcion', size=128, index=True, required=True)

@api.multi
@api.depends('code', 'name')
def name_get(self):
result = []
for table in self:
l_name = table.code and table.code + ' - ' or ''
l_name += table.name
result.append((table.id, l_name ))
return result


# -*- coding: utf-8 -*-

from odoo import models, fields, api

class inv13(models.Model):
_inherit='account.invoice'
tdoc=fields.Many2one('einvoice.catalog.01')
seri=fields.Char(string="seri")
corr=fields.Char(string="Correlativo")
tcorr=fields.Char(string="Union All")

@api.onchange(tdoc)
def change_tdoc(self):
        self.seri="A001"
self.tcorr=str(self.tdoc.code)+seri
