So I am trying to print an invoice with the xmlrpc api. I used the example from the api docs (https://doc.odoo.com/6.1/developer/12_api/#python-example) but it seems not to work.


import xmlrpclib
import time
import base64

u = '****'
pwd = '****'
db = '****'

sock_common = xmlrpclib.ServerProxy('http://*********:8069/xmlrpc/common')
uid = sock_common.login(db, u, pwd)

sock_print = xmlrpclib.ServerProxy('http://*********:8069/xmlrpc/report')
report_id = sock_print.report(db, uid, pwd, 'account.invoice', [1], {'model': 'account.invoice', 'id': 1, 'report_type': 'pdf'})


state = False
attempt = 0

while not state:
    report = sock_print.report_get(db, uid, pwd, report_id)
    state = report['state']
    if not state:
        attempt += 1
    if attempt > 200:
        print 'Abort, too long delay'

pdf_string = base64.decodestring(report['result'])
pdf_file = open('/tmp/file.pdf', 'w')

Does anyone know what the problem might be?

Well, the error tells you the report does not exist, so it is most likely looking for a report name that is not present in the database.

You are most likely using Odoo 8 or up (because I spotted the old_api in the stack trace) and when I search my own database, there is indeed no such report.

Try replacing the search line:

report_id = sock_print.report(db, uid, pwd, 'account.invoice', [1], {'model': 'account.invoice', 'id': 1, 'report_type': 'pdf'})
report_id = sock_print.report(db, uid, pwd, 'account.invoice', [1], {'model': 'account.invoice', 'id': 1, 'report_type': 'qweb-pdf'})


And see if that works. I can't check it for you now, so it is a guess.

Thank you for your answers, it helped me understand the problem better. After fooling around with erppeek and studying the source code, i've come to the conclusion that the report for account.invoice does not exist. I used account.report_invoice instead and it works like a charm!

And indeed, the report_type should be qweb-pdf. The resulting call:

report_id = sock_print.report(db, uid, pwd, 'account.report_invoice', [1], {'model': 'account.report_invoice', 'id': 1, 'report_type': 'qweb-pdf'})

Thanks again :)

The trouble is the name of the report.

"Required report does not exist: NoneTraceback (most recent call last):"

MAy you can check your report name and path line by line with print... so some debuging process must in this case.
