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

[elebumm]

I followed all the instructions to get this deployed and when I run the server and connect using Google Chrome I get this error here. I am unsure as to how to fix this.

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.

[elebumm]

This has something to do with the DebugToolbarMiddleware I believe

[elebumm]

So I disabled DEBUG mode and changed ALLOWED_HOSTS now the website loads but I get no css?

[acidjunk]

Did you run manage.py collectstatic
(seems you never did setup Django for production)

[elebumm]

I never ran that but after running it I got this error:

raise ImproperlyConfigured("You're using the staticfiles app " django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path

[acidjunk]

Deploying an Django app in production involves more then adding an item to ALLOWED_HOSTS and turning off debug. https://docs.djangoproject.com/en/1.10/howto/deployment/checklist/

Not only should you setup and folder that will contain the selected static files, you probably also have to configure part of your webserver for it. Same goes for MEDIA_FILES.

elebumm,

You need to add and modify the following info:

development.py file:
Django Debug Toolbar (you need to modify to add the name of the app)
INSTALLED_APPS += (
'debug_toolbar',)
#'debug_toolbar.apps.DebugToolbarConfig',)

Django Debug Toolbar Middleware (and you need to add the middleware classes.
MIDDLEWARE_CLASSES += (
'debug_toolbar.middleware.DebugToolbarMiddleware',
)

finally in the urls.py file add the following:

if settings.DEBUG:
    import debug_toolbar

urlpatterns += (
    url(r'^__debug__/', include(debug_toolbar.urls)),
)

I hope you found this helpful.

I followed the documentation and also get the same error. More or less new to Django, so this is frustrating.

[artforlife]

There seems to be some kind of compatibility problem. I have tried this on 1.8-1.10 and they all break with different errors (missing or undefined includes).

You have to explicitly setup debug_toolbar:

Add below line in your settings.py(in this case base.py):

DEBUG_TOOLBAR_PATCH_SETTINGS = False

Add the Debug Toolbar’s URLs to your project’s URLconf as follows:

from django.conf import settings
from django.conf.urls import include, patterns, url

if settings.DEBUG:
    import debug_toolbar
    urlpatterns += patterns('',
        url(r'^__debug__/', include(debug_toolbar.urls)),
    )

Then Enable Debug Toolbar in your MIDDLEWARE_CLASSES as follows:

(Add below line in your settings.py(in this case base.py) inside MIDDLEWARE_CLASSES you have to add )

'debug_toolbar.middleware.DebugToolbarMiddleware',

Save and runserver:

python manage.py runserver

Hi all,

Sorry for these issues due to significant upstream changes in Django Toolbar. I was trying to figure out the most appropriate migration path. I also did not want to change any non-development code as Django toolbar should be limited to development only.

I have made my latest commit 3a17284 to the master to fix these issues. I recommend upgrading all pip packages and then rerunning the installation. Or you can learn the changes from the commit and apply them to your existing projects.

Would like to thank @elebumm, @acidjunk , @medincar , @artforlife and @emilgeorgejames1 for your helpful inputs. You are really the ones taking this project to the edge! 😄

Please comment here if you face any problems now. I shall close this issue in a few days.

Thanks!
Arun

I faced the same issue today. I use ngrok to tunnel the local to internet . I get this error #67. No problem when I use in localhost. #
I then added '.ngrok.com' to ALLOWED_HOSTS and everything works fine now.

Hi, It is working fine in Production but not able to see CSS, even not after runnint 'python manage.py collectstatic'

[arshpreetsingh]

It worked fine now. This tutorial helped me to make application live on Production. https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04 may be I can write more details in the docs about deploying on Production
