django.urls.exceptions.NoReverseMatch: 'djdt' is not a registered namespace

Hi there,

I'm trying to configure django-debug-toolbar. As of now i did the following :

settings.py

DEBUG=True
if DEBUG:
INSTALLED_APPS += [ "debug_toolbar", ]

MIDDLEWARE += [
    "debug_toolbar.middleware.DebugToolbarMiddleware",
]

INTERNAL_IPS = [
    "127.0.0.1",
]

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",
]

DEBUG_TOOLBAR_CONFIG = {
    "SHOW_TOOLBAR_CALLBACK": lambda request: DEBUG,
    "RESULTS_CACHE_SIZE": 3,
    "SHOW_COLLAPSED": True,
    "SQL_WARNING_THRESHOLD": 100,
}

urls.py

if settings.DEBUG:

import debug_toolbar

urlpatterns = [path("__debug__/", include(debug_toolbar.urls)),] + urlpatterns

The toolbar is working correctly, but when i run pytest tests/ or docker-compose run --rm app pytest tests/ i get this error :

django.urls.exceptions.NoReverseMatch: 'djdt' is not a registered namespace for some tests suite.

So, what did i missed ??
Thank's in advance

You should only include the debug toolbar's urls when settings.DEBUG == True. Then your tests should run with DEBUG set to False.

Thank you @tim-schilling for your response
I already tested this option and it works : setting DEBUG=False means tests pass but debug toolbar does not show in the browser.
My goal is to include debug toolbar and run tests with DEBUG=True
Is this possible ?

[tim-schilling]

You could configure the debug toolbar with an environment variable, then run runserver with it set, such as TOOLBAR="True" python manage.py runserver

Or you can create a separate local settings file and use that in the call to runserver via python manage.py runserver --settings=config.settings.local where config.settings.local is the python path to your local settings file.

If you have it available, there's a chapter on Settings and Requirements files in Two Scoops of Django that goes into detail about this.
