How to download a file with button that executes a method in odoo 10?

I've got a wizard with it I want to create and download a file. The file will be gotten from a selection. It can be a qweb report, xml, xlst, ... .

When the button is clicked the method generates the selected file. I want it to pass to the browser for download. I know I can save the file in a binary field, but then the user needs to click on it, so I want to skip this step.

I know that I can download reports with

<button name="%(action_of_the_qweb_report)d" string="Get Document" type="action"/>

and from the odoo "website" when i get it from ir.attachments:

fileheaders = [
	('Content-Type', tmp_file[0].file_mimetype),
	('Content-Length', len(downlaod_file)),
	('Content-Disposition', 'attachment; filename="{}"'.format(tmp_file[0].name))
]

return request.make_response(downlaod_file, headers=fileheaders)

But I would like to do this from a odoo module. The problem is that files can be different types and some of them like xml are generated with python scripts.

So is there a way to just pass the file to the browser?
