Hi all

I have checked the unique phone number validation with @api.constrains

​class ResPartnerInherits(models.Model):

_inherit = 'res.partner'

​@api.constrains('phone')

​ def _mobile_filed_validation(self):

​ ​ for rec in self:

​ ​ ​ if rec.phone:

​ ​ ​ ​ existing_partner = self.search([('phone', '=', rec.phone)])

​ ​ ​ if existing_partner:

​ ​ ​ ​raise ValidationError("A contact with the same phone number already exists.")

Im getting the output a validation error "A contact with the same phone number already exists."  even though when I enter a unique phone number

What I have rectified here is even if i enter a unique phone number which doesn't exist in the database im getting the validation error and when I try to debug the code it gives me a res partner object (ex res.partner(930)) which doesnt exist in the database

Can anyone assist me in rectifying where the res_partner object with the id is getting stored 

1. Cache/cookies/session/local storage of the browser

2. In some temporary table in the database
