Hello All,
i want to generate barcode based on my record unique sequence that i am generating in record creation time. I want to create barcode for all record and display in report.
How to do this without custom module. Can odoo provides inbuilt feature?
Thanks in advance..
hope this works<img t-att-src="'/report/barcode/?type=%s&value=%s&width=%s&height=%s' % ('Code128', o.your_sequence, 600, 100)" style="width:300px;height:50px"/>
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
