I'm using Odoo17 and I want to print PDF Report from Wizard. The Wizard works fine, when I click on the button that trigger the function to print the PDF it download a blank PDF. To keep things simple, I'm not gonna publish all the code. So basically here are my files :

wizard/wizard_model

class ModelWizard (models.TransientModel):
   _name = 'project.pdf.report'
   _description='display printed informations'
   
   info= fields.Char()
   
   def print_report(self):
     print(self.env.context)
     data = {
           'model_id': self.id,
           'form': self.env.context
       }

     return self.env.ref('my_addon.action_report_Pdf').report_action(None, data=data)

Then I got my action file :

report/ir_actions_report

       My PDF

       project.pdf.report

       qweb-pdf

       my_addon.my_pdf

       my_addon.my_pdf

       'Name

       report

And finally my template:

I must have missed something. When the PDF is download the file got  name instead of . And page is blank, no header nor footer.

Could you help please ?

Thanks!!
