How to access a value of a many2one field from a form submitted in openerp?

on 9/10/14, 3:01 AM 1,229 views

I have a quotation form with a many2one field (x_delivery_periods) in openerp. Before write to database, I want to calculate the committed date using the function field (commitment_date). So I write the following code.


    def _get_commitment_date(self, cr, uid, ids, name, arg, context=None):

            res = {}
            dates_list = []
            deliveryperiod_obj = self.pool.get('stock.deliveryperiods')
            for order in self.browse(cr, uid, ids, context=context):
                dates_list = []

                deliveryperiod_read_test = deliveryperiod_obj.read(cr, uid, 4, ['name'], context) #working
                deliveryperiod_browse_test = deliveryperiod_obj.browse(cr,uid,4).name #working
                print deliveryperiod_read_test #working displays 10.0
                print deliveryperiod_browse_test #working displays {'name': 10.0, 'id': 4}

                print order.x_deliveryperiod #working displays browse_record(stock.deliveryperiods, 4)
                deliveryperiod_read = deliveryperiod_obj.read(cr, uid, order.x_deliveryperiod, ['name'], context) #not working TypeError: argument 2 to map() must support iteration
                deliveryperiod_browse = deliveryperiod_obj.browse(cr,uid,order.x_deliveryperiod).name #not working TypeError: argument 2 to map() must support iteration
                print deliveryperiod_read
                print deliveryperiod_browse

                dt = datetime.strptime(order.date_order, '%Y-%m-%d') + relativedelta(days=deliveryperiod_read or 0.0)
                dt_s = dt.strftime('%Y-%m-%d')
                if dates_list:
                    res[order.id] = min(dates_list)
            return res

        _columns = {
            'commitment_date': fields.function(_get_commitment_date, store=True, type='date', string='Commitment Date', help="Committed date for delivery."),


But while fetching the data from self.browse oblect results the above errors. Any help will be highly appreciated . Thanks in advance.

Just make the change as like below.

deliveryperiod_read = deliveryperiod_obj.read(cr, uid, order.x_deliveryperiod.id, ['name'], context)

deliveryperiod_browse = deliveryperiod_obj.browse(cr,uid,order.x_deliveryperiod.id).name

Note : You have to pass "Id" integer value to read and browse method.
