Thanks Rakesh,

It's working for report/Qweb side. But how to do this for backend side, means when i am creating new record and when i save that record then i am generating sequence and set to field and i have taken one image(Binary field) to store barcode for the generated sequence then how it is possible in backend side,

I know that when we run /report/barcode.. controller then it generate barcode and return. But for backend side? how to easily call that controller or any easier way??

Thank you for help.. :D

Hi,

In .py file:

def generate_barcode(self):
   data = {
       'response': self.name,
   }
   return self.env.ref('module_name.action_generate_barcode').report_action(self,data=data)

In Button Xml:

<header>


            <button name="generate_barcode" string="Generate Barcode" type="object"/>


</header>

In barcode_action.xml:

<?xml version="1.0" encoding="utf-8"?>


 <odoo>


       <record id="action_generate_barcode" model="ir.actions.report">


            <field name="name"> Barcode</field>


            <field name="model">module.name</field>


            <field name="report_type">qweb-pdf</field>


            <field name="report_name">module_name.print_barcode</field>


            <field name="report_file">module_name.print_barcode</field>


      </record>


</odoo>


In barcode_template.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<odoo>
<template id="print_barcode_custom">
    <t t-call="web.basic_layout">
        <div class="page">
            <div class="col-md-6">
                <img class="barcode"
                     t-att-src="'/report/barcode/?barcode_type=%s&amp;value=%s&amp;width=%s&amp;height=%s&amp;humanreadable=1&amp;quiet=0' % ('Code128',response, 205, 67)"
                     alt="Barcode"/>
            </div>
        </div>
    </t>
</template>
</odoo>
