Happy new year to everybody.

i want to get the net amount to pay to the employee in a costum field i have just created. I am not developper but i creat a function field in the hr.payslip model and write this function but it is not working

def _get_payslip_net(self, cr, uid, ids, name, args, context):
        if not ids: return {}
        res = {}
        for line in line_ids.browse(cr, uid, ids, context=context):
            if line.code=="NET":
                res[line.id] = line.total
        return res

 

Thanks in advance.
