Django Debug Toolbar prevents logging/tracebacks appearing in runserver

Let’s say I start Django channels server with command: python3 manage.py runserver 0.0.0.0:8001 There is no any customisation in settings.py regarding Logging except DEBUG = True

And all what I can see in logging are 4 types of messages: WebSocket HANDSHAKING, WebSocket CONNECT, WebSocket DISCONNECT and WebSocket REJECT

Even if I set assert False right before self.connect(), the only logs I get:

WebSocket HANDSHAKING /core/ [192.168.122.4:52494]
WebSocket DISCONNECT /core/ [192.168.122.4:52494]

Yes, just 2 lines. Nothing about assertion error or anything else.

This is how it suppose to be? How can I see the same logging that shows errors as it was on WSGI?

I’m using latest channels package, taken from github. There are some “fixes” in runserver.py file, but still the same. No normal logging, just messages about websocket sessions state.

Sorry to reopen this discussion with a comment. But this mades lost days of works, trying to find a proper solution, I particularly have lot of rules in my LOGGING config so disabling the logging in the develop mode was really inconvenient.

Another solution and a more clean one, is to remove the logging panel that is enable by default in django debug toolbar.

DEBUG_TOOLBAR_PANELS = [
    "debug_toolbar.panels.versions.VersionsPanel",
    "debug_toolbar.panels.timer.TimerPanel",
    "debug_toolbar.panels.settings.SettingsPanel",
    "debug_toolbar.panels.headers.HeadersPanel",
    "debug_toolbar.panels.request.RequestPanel",
    "debug_toolbar.panels.sql.SQLPanel",
    "debug_toolbar.panels.staticfiles.StaticFilesPanel",
    "debug_toolbar.panels.templates.TemplatesPanel",
    "debug_toolbar.panels.cache.CachePanel",
    "debug_toolbar.panels.signals.SignalsPanel",
    # "debug_toolbar.panels.logging.LoggingPanel",
    "debug_toolbar.panels.redirects.RedirectsPanel",
    "debug_toolbar.panels.profiling.ProfilingPanel",
]

Just that fixes the issues, you keep django debug toolbar working for your http requests and have also the tracebacks in the console.

Hope is useful for others

Thanks for reminding me of that, @matthiask! I will close this.
