Openerp 7 based on this requirement Sale order lines Remaining days Calculate Start Date minus Today at all times. Functional Field and on_change function used:-

def _remaining_days(self, cr, uid, ids, field_name, arg, context=None):
            res = {}
            if not ids:
                return {}
            for val in self.browse(cr, uid, ids, context=context):
                result = datetime.datetime.strptime(val.start_date, '%Y-%m-%d') - datetime.datetime.strptime(current_date, '%Y-%m-%d')
                res[val.id] = result.days
            return res

    'remaining_days': fields.function(_remaining_days, method=True, string='Remaining days', type='integer'),

    def onchange_holddays(self, cr, uid, ids, start_date, context=None):
        result = {}  
        context = context or {}
        if release_date:
            current_date = time.strftime('%Y-%m-%d')
            remaining = datetime.datetime.strptime(release_date, '%Y-%m-%d') - datetime.datetime.strptime(current_date, '%Y-%m-%d')
            result['remaining_days'] = remaining.days                
        return {'value': result}

In order lines Remaining days Values not updated automatically. once save the main sale order record then only lines Remaining days value updated. How to shows the remaining days values in list view before saving the record.

Functional field will have value only after you save the record.

Based on the requirement "Remaining days Calculate Start Date minus Today at all times" is it possible to any other way to shows remaining days in lines before saving the record. Because our client to see the output before saving the record.

Make your field float type and then return the calculated value from on_change.

Thanks for reply but in our case remaining days [Float data type] Daily need to update automatically based on [Start Date - Today]. After changing Functional field into Float field the daily auto calculation will not work based on this situation how to apply the auto calculation?

I think based on Sever action and Schedule action use but in that case also have problem reaming days non editable field [readonly=True]. In readonly field output not shown please guide me the right direction to solve this issue. Thanks
