Odoo11 Custom Report with Wizard - odoo

Question

I would like to print some product barcodes with the custom configuration.
Now, the problem is, I have created the wizard but when I click the print button there is no data is transferred to the report.
class BarcodeConfig(models.Model):
_name = 'report.barcode.print'
#api.model
def _default_product_line(self):
active_ids = self._context.get('active_ids', [])
products = self.env['product.product'].browse(active_ids)
return [(0, 0, {'product_id': x.id, 'qty': 1}) for x in products]
product_line = fields.One2many('product.print.wizard', 'barcode_id', string="Products",
default=_default_product_line)
#api.multi
def print_report(self):
data = self.read()[0]
ids = [x.product_id.id for x in self.product_line]
config = self.env['barcode.config'].get_values()
data.update({
'config': config
})
datas = {'ids': ids,
'form': data
}
return self.env.ref('odoo_barcode.barcode_report').report_action(self,data=datas)
In the above code, I had ids as well for product.product model.
<template id="report_barcode_temp">
<t t-call="web.html_container">
<t t-call="web.internal_layout">
<div class="page">
<h2>Report title</h2>
<strong t-esc="docs"/>
<strong t-esc="doc_ids"/>
<span t-esc="data"/>
<t t-foreach="docs" t-as="o">
<span t-esc="o"/>
<p>This object's name is
<span t-field="o.name"/>
</p>
</t>
</div>
</t>
</t>
In the above code, I'm just trying to print what the data's I've, but I've nothing in docs.
<strong t-esc="docs"/>
this line print product.product model as well. but ids not here, That's the problem I have.
Can anyone help me to tell why this happens? Or is there any other way to achieve this?

I have solved this by get_report_values method.
class classname(models.AbstractModel):
_name = 'report.modulename.templatename'
#api.model
def get_report_values(self, docids, data=None):
# docids: pass from the wizard print button.
records = self.env[objectname].browse(docids)
return {
'doc_ids': docids,
'doc_model': objectname,
'docs': records,
'data': data,}
