how to get Picking barcode ( serial number not the image ) in python

Question

Hi,
In odoo, you can print picking barcode. This mecanism is based on the name of the picking that is sent to controller /web/report/.. and returns a png.
However, i would like to get the *serial number* (123456789012..) of the generated barcode because i need to print it in zebra label. is there a way to do so ?

I think about adding a new field *barcode* to picking and generate one barcode on my own . but that would also mean i need to change the report to consider it instead of the name of th

Picking does not have any field to store the barcode serial number which you are looking for.
The system uses the "*name*" field of the picking to generate the barcode label in the report pdf.
If you scan the barcode label, it will give you the value of the picking name only and not the serial numbers.
You can see the following code using "*o.name*":
<img t-att-src="'/report/barcode/?type=%s&value=%s&width=%s&height=%s' % ('Code128', *o.name*, 600, 100)" style="width:300px;height:50p
