Django-debug-toolbar: process() missing 1 required positional argument: 'stream'

Created on 20 Jul 2016 · 11Comments · Source: jazzband/django-debug-toolbar

This cropped up on a few of our applications today, specifically when we rebuilt some Vagrant boxes. It might be related to #852 since it doesn't crop up on existing Vagrant boxes, meaning I'm wondering if a fresh install of everything means a newer version of an underlying dependency (like sqlparse), although in one case sqlparse was at 0.1.18 and we still ran into the issue.

At any rate, here's more information -- this is on Django 1.9.5, but the same occurs on Django 1.9.7. Let me know if I can provide additional information.

@zhukandrey it's better you upgrade the toolbar's version to 1.5 instead. It's been released on pypi already: https://pypi.python.org/pypi/django-debug-toolbar

It's absolutely because of sqlparse 0.2 api change.

I'm seeing this locally as well. Is there a workaround?

@iMerika just add 'sqlparse <0.2' to your dependencies (either requirements.txt or setup.py) explicitly to lock out incompatible version of this package.
