Here is my python file

# -*- coding: utf-8 -*-
from odoo import api, models
from gevent.hub import sleep
class MrpTest(models.AbstractModel):
    _name = 'production_report.report'
    @api.multi
    def render_html(self, docids, data=None):
        production_obj = self.env['mrp.production'].browse(docids)
        workorder_lines = []
        for production in production_obj.workorder_ids:
            bar_data = workorder.name 
            barcode = code128.Code128(bar_data.encode('utf-8')) 
            barcode.barWidth = inch * 0.008 
            barcode.barHeight = 0.3 * inch
            print 'barcode ::',bar_data
            workorder_line ={'name':bar_data,
                             'production_id':workorder.production_id,
                             'qty_workorder':workorder.qty_workorder,
                             'workcenter_id':workorder.workcenter_id,
                            }
            workorder_lines += [workorder_line]
        docargs = {
            'doc_ids': docids,
            'doc_model': 'mrp.production',
            'lines':workorder_lines,
            'docs': self.env['mrp.production'].browse(docids),
            'data': data,
            'barcode':barcode
        }   
        return self.env['report'].render('report_test',  {'lines': workorder_lines})

The problem is :

1. My xml, python file doesn't connect

2. I can't print barcode \example value is :: сайна уу\
