img t-att-src="'/report/barcode/Code128/'+o.name + o.ref" style="width:200px;height:50px" alt="Barcode"


note: for a single value o.name its working fine, i can scan & check value through mobile app, but when concatenate 2 fields o.name + o.ref , its generating barcode in PDF but it is not showing anything when scanning through mobile app. means the generated barcode is not valid.

Please use the following code snippet without the '+' symbol and unwanted ''

<img t-attf-src="/report/barcode/Code128/{{o.name}}{{o.ref}}" style="width:200px;height:50px" alt="Barcode"/>

Hi,

There are multiple ways to concatenate two fields in a QWEB template. One approach is to use the `t-attf` property instead of `t-att`. Here is an example:

o.name}}{{o.ref}}" style="width:200px;height:50px" alt="Barcode">


By using `t-attf`, we can concatenate the values of the `o.name` and `o.ref` fields to construct the source URL for the barcode image. This makes the code more readable and allows for dynamic concatenation of field values

Hope it helps
