        from
            hr_holidays h
            join hr_holidays_status s on (s.id=h.holiday_status_id)
        where

            s.limit=False and
            h.employee_id in %s
        group by h.employee_id""", (tuple(ids),))
    res = cr.dictfetchall()
    remaining = {}
    for r in res:
        remaining[r['employee_id']] = r['days']
    for employee_id in ids:
        if not remaining.get(employee_id):

    partner_id = fields.Many2one('res.partner', string="Customer")
    remaining_leaves = fields.Char(string='Leaves remaining')


    def _get_remaining_days(self, cr, uid, ids, name, args, context=None):
        res = super(hr_holidays,self)._get_remaining_days(cr, uid, ids, name, args, context)

please help me

Answer 1

You have to call the right Class in super():

res = super(HrHolidays, self)._get_remaining_days(
    cr, uid, ids, name, args, context)

Answer 2

You need to call super with HrHolidays and pass just name and args to _get_remaining_days method and override remaining_leaves field:

Python

class HrHolidays(models.Model):
_inherit = 'hr.employee'

@api.model
def _get_remaining_days(self):
    res = super(HrHolidays, self)._get_remaining_days(name='', args={})
    for record in self:
        if record.id in res:
            record.remaining_leaves = res.get(record.id)

    return res

remaining_leaves = fields.Float(compute='_get_remaining_days',
                    string='Remaining Legal Leaves')

Answer 3

thanks for all , but i got problem in the field ,i want to award my function to my field i have done that but isn't work :

    remaining_leaves = fields.Function(_get_remaining_days,string='Leaves')

i got this error

Answer 4

我认为该功能有效，但我无法通过fields.function显示它

   remaining_leaves = fields.Function(_get_remaining_days,string='Leaves')
