Odoo onchange method is not saving values in readonly fields

onchange

Ernesto Ruiz

In my view I have a Boolean field (chk_valido) and two other fields. I want those fields to get the value of the current user and the current date, when the boolean fields is set to True. With this code the fields are getting the value but when I click the "Save" button those values desapear. What is causing these issue? How can i save those values? "user_valido" and "fecha_validaciongabinete" are set to readoly in the view

chk_valido = fields.Boolean(string='Está validado')
user_valido = fields.Many2one('res.users', string='Usuario valido')
fecha_validaciongabinete = fields.Datetime(string='Fecha Validacion gabinete')

@api.onchange('chk_valido')
def _onchange_chk_valido(self):
    if self.chk_valido:
        self.fecha_validaciongabinete=fields.Datetime.today()
        self.user_valido= self.env.user
    else:
        self.fecha_validaciongabinete=""
        self.user_valido=False

Hi,

if you are using odoo latest version give force_save="1" along with field definition in XML.

See :-https://www.youtube.com/watch?v=XEnvGQilBk8

from openerp import models, fields, api,exceptions

class your_model(models.Model):

_inherit = 'your.model'

field_1 =fields.Many2one('model.a', required="True", string="Field 1")

field_2 = fields.Integer(string = 'Field 2')

# onchange of field_1 we are populating value in field_2

@api.onchange('field_1')

def _onchange_field_1(self):

if field_1:

# your logic goes here to get value for field_2

self.field_2 = some_value

# As we know that when we get the value on onchange method,

# the desired field convert into readonly mode and its value does not save into the database

# to save the value into the database we are going to override create and write method and in that method we explicitly save the value

@api.model

def create(self,vals):

if self.field_2:

vals['field_2']=self.field_1

res = super(your_model, self).create(vals)

return res

@api.multi

def write(self,vals):

if not self.field_2:

vals['field_2'] = self.field_1

res = super(your_model, self).write(vals)

return res

Save Readonly Field in Database

CHAREF Abdelmoula

You can try this : <field name="field_name" readonly="1" force_save="1"/>

Explanation:when using onchange on a readonly field value when changed can't be stored to the database ,You can use this to force saving its value,

gd luck
