I’m using Odoo 17 and I added a custom button on the project form view that displays wizard view to recap some informations and then export them inside a PDF report. Everything works fine except one thing : I can’t change the name of the PDF. Here is my code :

report/ir_actions_report.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>
   <record id="action_report_custom" model="ir.actions.report">
       <field name="name">My Custom PDF</field>
       <field name="model">report.custom_module.my_report</field>
       <field name="report_type">qweb-pdf</field>
       <field name="report_name">custom_module.my_report</field>
       <field name="report_file">custom_module.my_report</field>
       <field name="print_report_name">'the name of the file'</field>
       <field name="binding_type">report</field>
   </record>
</odoo>

report/custom_report.py

from odoo import api, models

class CustomReport(models.AbstractModel):
   _name = 'report.custom_module.my_report'
   description = 'desc'
   @api.model
   def _get_report_values(self, data=None):
        return {
              'docs': data,
              'doc_model':'project.pdf.report',
              'data': data['context']['x'],
        }
          

When I don’t generate the report through the native print button instead, in the project model, the field <field name="print_report_name"> works fine. But through a custom button, it doesn’t, it keeps using the field <field name="name">.

Any idea about how to change report file name through wizard?

Thanks a lot
