Hi,

If you want to inherit the functional fields and make some changes, you may redefine the fields and function in new api and make the changes you need. For eg, you may try like this:

class hr_employee(models.Model):
    _inherit="hr.employee"
    
    current_leave_id = fields.Many2one('hr.holidays.status', compute='_get_leave_status', string="Current Leave Type")
    leave_date_from = fields.Date(compute='_get_leave_status', string='From Date')
    leave_date_to = fields.Date(compute='_get_leave_status', string='To Date')
    
    
    @api.one
    @api.depends('employee_id')
    def _get_leave_status(self):
        holidays_obj = self.env['hr.holidays']
        holidays = holidays_obj.search([('employee_id', 'in', self.ids), ('date_from','<=',time.strftime('%Y-%m-%d %H:%M:%S')),
           ('date_to','>=',time.strftime('%Y-%m-%d 23:59:59')),('type','=','remove'),('state','not in',('cancel','refuse'))])

        for holiday in holidays:
            self.leave_date_from = holiday.date_from
            self.leave_date_to = holiday.date_to
            self.current_leave_state = holiday.state
            self.current_leave_id = holiday.holiday_status_id.id

Please check it n let me know.

Hi, that's fine now able to inherit but in the function I have changed main code because 'self' contained all employees ,So I looped on self instead of holidays as per this code it raising error, So I modified like this working fine  

@api.multi

def _get_leave_status(self):

holidays_obj = self.env['hr.holidays']

print self.ids,'holidays_id****In INHERIT***********-------------------------',fields.date.context_today(self,self.env.cr,self.env.uid)

print self.env.context,'Context ***********8-------------------------',self,self.env.cr,self.env.uid

holidays_id = holidays_obj.search(

[('employee_id', 'in', self.ids), ('leave_from','<=',fields.date.context_today(self,self.env.cr,self.env.uid)),

('leave_to','>=',fields.date.context_today(self,self.env.cr,self.env.uid)),('type','=','remove'),('state','not in',('cancel','refuse'))],

)

print holidays_id,'holidays_id****In INHERIT***********-------------------------',fields.date.context_today(self,self.env.cr,self.env.uid)

#result = {}

'''

for id in ids:

result[id] = {

'current_leave_state': False,

'current_leave_id': False,

'leave_date_from':False,

'leave_date_to':False,

}

'''

for holiday in holidays_id:

print holiday,'****************************',holiday.holiday_status_id.id

for rec in self:

print rec.ids,'Rec*88888888888888888888'

holidays_id = holidays_obj.search(

[('employee_id', 'in', rec.ids), ('leave_from','<=',fields.date.context_today(self,self.env.cr,self.env.uid)),

('leave_to','>=',fields.date.context_today(self,self.env.cr,self.env.uid)),('type','=','remove'),('state','not in',('cancel','refuse'))],

)

rec.leave_date_from = holidays_id and holidays_id[0].date_from or None

rec.leave_date_to = holidays_id and holidays_id[0].date_to or None

rec.current_leave_state = holidays_id and holidays_id[0].state or None

rec.current_leave_id = holidays_id and holidays_id[0].holiday_status_id.id or None

Thanks
