I try to get current id in onchange method before saving this contact using

self.id ==> output is <odoo.models.NewId object at 0x7f72aff2b290>

self._origin.id==>False

self.env.context.get('active_ids')==>None

I know that I have to use self._origin.id in onchange method for saved contact.

How can I get current id before saving?

Here is my code

@api.multi

@api.onchange("mobile")

def onchange_mobile(self):

logging.info("self id")

logging.info(self.id)

logging.info(self._origin)

logging.info(self.env.context.get('active_ids'))

mobile_id=self.search([('mobile','=',self.mobile),('id','!=',self.id)])

if mobile_id:

raise ValidationError(_("similar mobile number are found"))

else:

raise ValidationError(_('No Similar Mobile'))
