Hi

I am trying to save a many2one field value in settings. But it is not saving, after refreshing the page the field value is set to false.

This is my code:

partner = fields.Many2one('res.partner')

@api.model
def get_values(self):
  res = super(Partner, self).get_values()
  res['partner'] = self.env['ir.config_parameter'].sudo().get_param(
      'projectxyz.partner.id')
  return res

@api.model
def set_values(self):
  res = super(Partner, self).set_values()
  self.env['ir.config_parameter'].sudo().set_param('projectxyz.partner',
                                                    self.partner.id)
  return res
