Hi there,

Im trying to change product_id field domain based on a boolean in the sale order form view.

Please let me know what Im doing wrong or if there is any other approach. Thanks!

So this is what I have tried:

My xml file:

<?xml version="1.0" encoding="utf-8"?>
<openerp> 
   <data>
 
       <record id="view_order_form" model="ir.ui.view"> 
   <field name="name">prointer.view_order_form</field>
    <field name="model">sale.order</field>
    <field name="inherit_id" ref="sale.view_order_form" />
    <field name="priority">90</field> 
   <field name="arch" type="xml">
 
       <xpath expr="//field[@name='partner_id']" position="after">
         <field name="sale_type" on_change="change_product_id_type(sale_type)"/>
        <field name="product_id"/> <!-- this field gets updated-->
       </xpath>
 
       <xpath expr="//field[@name='order_line']/form//field[@name='product_id']" position="replace"> 
     <field name="product_id"/> <!--This field get override with my inherit but doesnt update with domain change-->
        </xpath>
     </field>

</record>
 
   </data>
</openerp>

My python file

from openerp import models, fields, api
import logging



class ProCustomSale(models.Model):

    _name = 'sale.order'
    _inherit = 'sale.order' 
 sale_type = fields.Boolean(string="Modo Venta", )
 @api.onchange('sale_type')
 def change_product_id_type(self, cr, uid, ids, sale_type, context=None):
 logging.info('changing domain')
 if sale_type: return {'domain': {'product_id': [('type', '!=', 'service')]}}
 else: return {'domain': {'product_id': [('type', '=', 'service')]}}
 
class ProCustomLine(models.Model): 
_name = 'sale.order.line' 
_inherit = 'sale.order.line' 
#this is the only way I can make it change,but the domain above doesnt do anything in the order line but if I make a new copy of the field anywhere else in the xml file,it works
product_id = fields.Many2one('product.product', 'Product2', domain=['&', ('sale_ok', '=', True), ('type', '=', 'service')], change_default=True, readonly=True, states={'draft': [('readonly', False)]}, ondelete='restrict')
 ProCustomSale()
ProCustomLine()
