is it possible to print multiple record many2many to the qweb in odoo 8 

because i tried its always passing one record. 

class WizProductionRecap(models.TransientModel):
_name = 'wiz.production.recap'


sale_id = fields.Many2many('sale.order', string="Sales Order", required=True)

@api.multi
def action_print(self):
    if self.sale_id:
        _logger.info("SALE ORDER sale_id: %s", self.sale_id)
        datas = {
            'ids': self._ids,
            'model': 'wiz.production.recap',
            'form': self.read()[0]
        }
        report_name = 'mrp_jewelry_pdo.report_production_recap_document'
        pdo_id = self.env['mrp.jewelry.pdo'].search([('sale_id', 'in', self.sale_id.ids)])
        if pdo_id:
            return self.env['report'].get_action(pdo_id[0], report_name, data=datas)
        else:
            return None


and the abstract

class ReportProductionRecap(models.AbstractModel):
    _name = 'report.mrp_jewelry_pdo.report_production_recap_document'

    @api.multi
    def render_html(self, data=None):
        _logger.info("RENDERING records: %s", self)
        report_obj = self.env['report']
        report = report_obj._get_report_from_name('mrp_jewelry_pdo.report_production_recap_document')

        pdo_obj = self.env['mrp.jewelry.pdo']
        docargs_list = []
        for record in self:
            pdo_records = pdo_obj.search([('sale_id', '=', record.id)])
            sales_orders = pdo_records.mapped('sale_id')

            docargs = {
                'doc_ids': self.env["wiz.production.recap"].browse(data["ids"]),
                'doc_model': report.model,
                'docs': self,
                'data': data,
                'pdo_id': pdo_records.ids,
                'sale_id': sales_orders.ids,
                'pdo_records': pdo_records,
                'sales_orders': sales_orders,
            }
            docargs_list.append(docargs)
        return [report_obj.render('mrp_jewelry_pdo.report_production_recap_document', docargs) for docargs in
                docargs_list]
