Odoo 13: Check if a user has only a single related employee

Question

I need to check if certain user has one and only one employee associated.

So far, I have this:

def _employee_get(obj, cr, uid, context=None):
    ids = obj.pool.get('hr.employee').search(cr, uid, [('user_id', '=', uid)], context=context)
    if ids:
        if len(ids) > 1:
            return False
        else:
            return ids[0]
    else:
        return False

class History(models.Model):
    _name = 'hospital.history'
    _description = 'hospital.history'

    date = fields.Date(required=True, default=fields.Date.today(), readonly=True)
    name = fields.Many2one('res.partner', string="Patient", required=True)
    healthworker = fields.Many2one('hr.employee', string='Sanitarian', default=_employee_get, readonly=True)
    testresults = fields.Text(string="Tests' Results")
    description = fields.Text(string="Description", required=True)
    specialities_ids = fields.Many2many('hospital.speciality', 'hospital_speciality_history_rel', 'history_id', 'speciality_id', 'Speciality')
    status = fields.Selection([('admitted','Admitted'),('outpatient','Outpatient Clinic')], 'Status', required=True)

But when I call the function I get this error:

TypeError: _employee_get() missing 2 required positional arguments: 'cr' and 'uid'

Have tried several different ways, but can't get it to work so any help will be much appreciated.

alfa,

You have performed the old code in the new version odoo(13).

This _employee_get method should be like this way :

def _employee_get(self):
    return self.env['hr.employee'].search([('user_id', '=', uid)], limit=1)
