how to print looped data from a method - odoo

Question

i created a method as below: but it only takes the last loop data not all the data to xml for generating pdf,so need a way to generate pdf on a loop from this method
def bsku_asin_picking(self):
website = self.env['website'].search([('company_id', '=', self.env.company.id)], limit=1)
# print('%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%', website.label_type)
# vals = []
for rec in self.move_ids_without_package:
product = self.env['product.product'].browse(rec.product_id.id)
data = {
'quantity': rec.product_uom_qty,
'display_name': product.display_name,
'product': product,
}
if website.label_type == 'bsku':
data['barcode_value'] = product.bsku
else:
data['barcode_value'] = product.asin
# vals.append(data)
return self.env.ref('product_label_bsku_sin.report_product_template_label').report_action(product, data=data)

Answer 1

The variables passed through data will be available in the rendering context.
Example:
def bsku_asin_picking(self):
website = self.env['website'].search([('company_id', '=', self.env.company.id)], limit=1)
vals = []
for rec in self.move_ids_without_package:
product = rec.product_id
product_data = {
'quantity': rec.product_uom_qty,
'display_name': product.display_name,
'product': product,
}
if website.label_type == 'bsku':
product_data['barcode_value'] = product.bsku
else:
product_data['barcode_value'] = product.asin
vals.append(product_data)
datas = {'vals': vals}
return self.env.ref('product_label_bsku_sin.action_report_product_template_label').report_action(self, data=datas)
Then you can loop over vals and print product data.
Example:
<t t-foreach="vals" t-as="product_data">
<p t-out="product_data['quantity']"/>
<p t-out="product_data['display_name']"/>
<p t-out="product_data['product']"/>
<p t-out="product_data['barcode_value']"/>
</t>
Alternative
You can also call report_action without data and loop over the move_ids_without_package:
Example:
<t t-set="website_label_type" t-value="doc.env['website'].search([('company_id', '=', doc.env.company.id)], limit=1)"/>
<t t-foreach="doc.move_ids_without_package" t-as="line">
<p t-out="line.product_uom_qty"/>
<p t-out="line.display_name"/>
<p t-out="line.product_id.name"/>
<t t-if="website_label_type == 'bsku'">
<span t-out="line.product_id.bsku"/>
</t>
<t t-else="">
<span t-out="line.product_id.asin"/>
</t>
</t>
