My model: Tenant.

In model Tenant I have field phone, I want when I create a new tenant (In case of creating a new account first (EX: login = "0123 456 789") , then create tenant), field "phone" in this model will link with field "login" in model res_users. 

On the contrary, in case of creating a new tenant first (Ex: 0123 456 789), when I create account in res_users, "login" in this model auto link with "phone" in tenant.

Model Tenant:

	​
class Tenant(models.Model):    
	_name = "pma.tenant"    
​_inherit = ["mail.thread", "mail.activity.mixin"]    
​_description = "Manager Tenant"    
​_order = "create_date desc"
name = fields.Char(string="Tenant Name", required=True)    
owner = fields.Many2one("res.users", string="Owner", required=True, default=lambda self: self.env.user)
    phone = fields.Char(string="Phone Number", required=True)    
	user = fields.Many2one("res.users")    
email = fields.Char(string="Email Address", required=True)   

    @api.onchange("phone")    
	def _compute_check_phone_number(self):        
		for record in self:            
			convert_phone = utils.convert_phone_to_global(self.phone)      
			if convert_phone:
				record.user = self.env["res.users"].search(                    				[("login", "=", convert_phone)])

Model Res_users:

class Users(models.Model):    
	_inherit = "res.users"
    
	@api.model_create_multi    
	def create(self, vals_list):        
		users = super(Users, self).create(vals_list)        
		for user in users:            
			convert_login = utils.convert_phone_to_vn(user.login)            			if convert_login: 
	              tenant = (self.env["pma.tenant"].sudo().search([("phone", 					"=", convert_login)]))
                tenant.write({"user": users.id})        
		return users



I have linked, but it only works in 1 case: creating a new Previous Tenant, creating an account will automatically link.

I want it works for bolh case.

Please help me ....
