I was trying to add aditional label formats using this module code: from collections import defaultdict from odoo import fields, models class ProductLabelLayout(models.TransientModel): _inherit = ' product.label.layout' [1] print_format = fields.Selection(selection_add=[ ('2x4', '2 x 4') ], ondelete={'2x4': 'set default'}) And i thought that would do it, but it leads to an error. Any ideas ? load could not load template ValueError: Invalid template id: '' Template: product.report_productlabel

I was trying to add aditional label formats using this module code:

from collections import defaultdict
from odoo import fields, models


class ProductLabelLayout(models.TransientModel):
    _inherit = 'product.label.layout'

    print_format = fields.Selection(selection_add=[
            ('2x4', '2 x 4')
        ], ondelete={'2x4': 'set default'})

And i thought that would do it, but it leads to an error. Any ideas ?

load could not load template
ValueError: Invalid template id: ''
Template: product.report_productlabel

You need to try this code.When we create new selection field on the prin_format you must add new functions for that types and need to create new printing format

from collections import defaultdict
from odoo import fields, models, _
from odoo.exceptions import UserError

class ProductLabelLayout(models.TransientModel):
_inherit = 'product.label.layout'

print_format = fields.Selection(selection_add=[
('price_card', 'Price Card'), ], ondelete={'price_card': 'set default'})

def _prepare_report_data(self):
xml_id, data = super()._prepare_report_data()

if 'price_card' in self.print_format:
xml_id = module_name.report_product_label_product_price_tag'

active_model = ''
if self.product_tmpl_ids:
products = self.product_tmpl_ids.ids
active_model = 'product.template'
elif self.product_ids:
products = self.product_ids.ids
active_model = 'product.product'
price = format(self.product_tmpl_ids.list_price, ".2f")
data = {
'active_model': active_model,
'product_tmpl_name': self.product_tmpl_ids.name,
'product_tmpl_price': price,
'product_tmpl': self.product_tmpl_ids,
'product_name': self.product_ids.name,
'product_id': self.product_ids,
}
return xml_id, data

def process(self):
action = super(ProductLabelLayout, self).process()
self.ensure_one()
xml_id, data = self._prepare_report_data()
if not xml_id:
raise UserError(_('Unable to find report template for %s format', self.print_format))
report_action = self.env.ref(xml_id).report_action(None, data=data)
report_action.update({'close_on_report_download': True})
return action

Also, try to add the paper format and further details

<record id="paperformat_product_price_tag" model="report.paperformat">
<field name="name">Price Card Label</field>
<field name="default" eval="True"/>
<field name="format">custom</field>
<field name="page_height">267</field>
<field name="page_width">175</field>
<field name="orientation">Landscape</field>
<field name="margin_top">0</field>
<field name="margin_bottom">0</field>
<field name="margin_left">0</field>
<field name="margin_right">0</field>
<field name="disable_shrinking" eval="True"/>
<field name="header_line" eval="False"/>
<field name="header_spacing">0</field>
<field name="dpi">96</field>
</record>
<record id="report_product_label_product_price_tag" model="ir.actions.report">
<field name="name">Product Price Card</field>
<field name="model">product.template</field>
<field name="report_type">qweb-pdf</field>
<field name="report_name">module_name.report_product_price_tag</field>
<field name="report_file">module_name.report_product_price_tag</field>
<field name="binding_type">report</field>
<field name="binding_model_id" ref="model_product_template"/>
<field name="paperformat_id" ref="paperformat_product_price_tag"/>
</record>
<template id="report_product_price_tag">
//content
</template>

Hope it helps
