I have a receipt form that lets you register payments. Now I wanna take the amount entered AFTER pressing the validate button and use it in another model. How can I do that?

you must have a relation field between class account voucher (but you do not give this information), with example I give after, with field voucher_id in class record, and use a field type related or function (use function type for better performance) depending of the amount field in class voucher which will give the value in the field amount in record class when field amount change in class voucher.

Never use an onchange for that because if I do a write from a function in current class or a write from an other class in this field, the onchange will be not used and the value will not change in the record class.

from openerp import models, fields, api

class Record(models.Model):

    _name= 'record'


    voucher_id = fields.Many2one('account.voucher', 'Voucher')

    amount = fields.Float(compute='_get_voucher_amount', string='Voucher amount')


    @api.depends('voucher_id', 'voucher_id.amount')

    def _get_voucher_amount(self):

        self.amount = self.voucher_id.amount


I'm getting this error when I run it: ProgrammingError: column record.voucher_id does not exist

Hi Cyril, I managed to get it working. But in my 'amount':fields.float(compute='_get_voucher_amount',string="Voucher Amount"), the _get_voucher_amount is not getting called. I have put a print statement in it but it just doesn't show.

update my code, forgot to add voucher_id in @depends, now when you will change voucher_id in class record, or amount in class account voucher, amount in class record will be updated, bye

here i using odoo 8. after press the amount in account.voucher model. u can get the amount value in another model. for that u just simply inherit the model in ur current model and use that value in ur current model.

from openerp import models, fields, api, _

class account_voucher(models.Model):

_inherit = 'account.voucher'


def onchange_amount(self, amount, rate, partner_id, journal_id, currency_id, ttype, date, payment_rate_currency_id, company_id):

print amount

return True

Thanks. How do I set the value of amount to the value of another variable which is in a model called 'record' ? Like record.amt=amount

yes. you simply assign tht amount to another value. like self.field_name=amount.
