QR Code in custom print format

Once you upgrade from version-13 to version-14 e-Invoice QR codes in your custom print format won't work anymore. This guide will help you to add QR code in custom print formats.

Step 1: Make a web template for QR Code

First you'll have to create a Web Template for the QR Code, to go to web template list search for Web Template in awesome bar and create a new Web Template. Give it a name something like "E-Invoice QR Code", type as "Component" and module as "Printing".

Step 2: Add web template to custom print format

Go to the custom print format where you wish to add the QR Code, replace the current QR Code image field with a custom HTML section and in that Custom HTML section past the code snippet mentioned below

{% if doc.irn %}
{% set e_invoice_log = frappe.db.get_value(
 "e-Invoice Log", doc.irn, ("invoice_data", "signed_qr_code"), as_dict=True
) %}

{%- set invoice_data = dict(json.loads(e_invoice_log.invoice_data)) -%}

##### **Transaction Details**




 {%
 set transaction_details = {
 "IRN": invoice_data.Irn,
 "Ack. No": invoice_data.AckNo,
 "Ack. Date": frappe.utils.format_datetime(
 invoice_data.AckDt, "dd/MM/yyyy hh:mm:ss"
 ),
 "Category": invoice_data.TranDtls.SupTyp,
 "Document Type": invoice_data.DocDtls.Typ,
 "Document No": invoice_data.DocDtls.No,
 }
 %}
 {% for key, value in transaction_details.items() %}

{{ key }}
{{ value }}

 {% endfor %}


 {{ web_block('E-Invoice QR Code', values={'qr_text': e_invoice_log.signed_qr_code }) }}
