Declare onchange method inside old API inherited model

Question

I'm trying to execute a method on user_id change in the sale.order model in Odoo v8, it use osv.osv class.
I create an inherited model with a models.Model class and use the @api.onchange decorator but nothing append.
# -*- coding: utf-8 -*-
from openerp import models, fields, api from openerp.exceptions import Warning class Order(models.Model):   _inherit = 'sale.order'   @api.onchange('user_id')   def on_saler_change(self):     raise Warning(('Something happened.')) How i suppose to do this?

Martin,

What you can do is,

Inherit form view of sale.order having user_id field and add onchange attribute to it as:
- <field name="user_id" position="attributes">
- - <attribute name="on_change">on_saler_change(user_id)</attribute>
- </field>
in .py inherit sale.order using old api only and define "on_saler_change(user_id)" in it

Hope it helps!

Hello Martin,

If this onchange method is from base module then call super for the same method.

*from openerp import models, fields, api, _*
*from openerp.exceptions import UserError*
*class Order(models.Model):*
*      _inherit = 'sale.order'*
*
*
*      @api.onchange('user_id')*
* 	    def on_saler_change(self):*
*            raise UserError(_('Something Happened'))*
*            return super(Order, self).on_saler_change()*

Hope it works for you.

Thanks,
