The operation cannot be completed, probably due to the following:

- deletion: you may be trying to delete a record while other records still reference it -

creation/update: a mandatory field is not correctly set

[object with reference: name - name]

class Employee(models.Model):

    _name = "hr.employee"

    _description = "Employee"

    _order = 'name_related'

    _inherits = {'resource.resource': "resource_id"}

    # _inherit = 'res.partner'

    _inherit = ['mail.thread']

    _inherit = 'res.partner'

    firstname = fields.Char("First name")

    lastname = fields.Char("Last name")

    name = fields.Char(compute='comp_name', store=True)

    @api.depends('firstname','lastname')

    def comp_name(self):

        self.name = (self.firstname or '')+' '+(self.lastname or '')

 can i get any solution please??
