How can i print a report from odoo server actions (GUI)

How can I make a server action in the GUI of odoo 10 to print the custom picking report Report id: id=690

(I am trying to make an automated action to print al new confirmed orders)

Solution

I just noticed that this module supports odoo 10

This is probably your best bet.

To get the report from the odoo server: {server}/report/pdf/{report_id}/{object_id} example:

https://odoo.yourcompany.com/report/pdf/account.report_invoice_with_payments/70

I don't have access to Odoo 10, but for modern Odoos you can generate the report like that:

pdf_data = self.env.ref('account.report_invoice_with_payments').with_user(SUPERUSER_ID)._render_qweb_pdf([invoice.id])[0]

This pdf_data is pdf data as bytes that can be posted to the server or saved to a file.
