Hi everybody,

I have many2one partner_id and one2many recommendation_ids fields in my form view. I need to return old partner_id value if there are some records in recommendation_ids field.

*.xml

<field name="partner_id" on_change="onchange_partner_id(partner_id, recommendation_ids)"/>
...
<field name="recommendation_ids" />

*.py

def onchange_partner_id(self, cr, uid, ids, partner_id, recommendation_ids, context=None):
    return {'value': old_partner_id}

Thanks

Please explain it better. Thanks

Hi, onchange event does not save the result of the onchange function to the database. It is saved only when we click on the save button. So if you browse the current record and fetch the partner_id, it will fetch the older partner_id.
