'jet' is not a registered namespace

[szabolcsdombi]

Django Version:    1.10.5
Exception Type:    NoReverseMatch
Exception Value:   'jet' is not a registered namespace

Using Python3.5

Steps:

• Run python3 -m pip install django-jet
• Added 'jet' as the first element in the INSTALLED_APPS
• Run python3 manage.py migrate

I am able to import jet using python3: python -c "import jet"

[szabolcsdombi]

With the same setup the django-suit works fine.

@f1nality Man, please.

[Ismael-VC]

@cprogrammer1994 it seems that we were both confused by the installation instructions.

Steps:

Run python3 -m pip install django-jet Added 'jet' as the first element in the INSTALLED_APPS Run python3 manage.py migrate

Notice you are lacking several steps to complete your installation ⚠️

In my case I was following the installation instructions from the README, at the point of the warning I mistakenly understood that the bullet points below the warning where for pre 1.8 django:

• https://github.com/geex-arts/django-jet#installation

It is easier to understand the installation instructions from the very well formatted and colored instructions at read the docs:

• http://jet.readthedocs.io/en/latest/install.html

Please try the instructions again, it works.

My advise is to remove the installation instructions from the README, as they are redundant since the docs are linked above in the same document. Also this instructions can become out of sync with the docs easily.

If you guys agree, I can make a PR for that, cheers!

[SalahAdDin]

@Ismael-VC I think there is a problem with migrations file, but i'm not sure. Hey, if you can will better make a PR and @f1nality can review it.

@f1nality

@dhouibkhouloud Hey, STATIC_ROOT setting to a filesystem path. Search it in google. PD: You have to set your STATIC_ROOT.

[shayneoneill]

Was this ever solved?

[merwok]

Exception Type:    NoReverseMatch
Exception Value:   'jet' is not a registered namespace

This is a URL configuration issue. In the install docs, we can see url(r'^jet/', include('jet.urls', 'jet')) added to urlpatterns: the last string is a URL namespace.

(That said, the docs seem to target older django versions, I don’t know if django-jet works with recent versions.)

[shayneoneill]

Yeah I found it in the end. Whoops.

I probably should have recognized the error lol. The joys of sleep deprivation.

[ghost]

By adding STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), "static") to the settings.py it worked fine ( :

[rowsheet]

reverse('jet-dashboard:update_module' is trying to reach the url /jet-dashboard or something with that namespace. Chances are your URL config looks like:

    re_path(r'^jet/', include(('jet.urls', 'jet'))),
    re_path(r'^jet/dashboard/', include(('jet.dashboard.urls', 'jet-dashboard'))),

It should look like:

    re_path(r'^jet/', include(('jet.urls', 'jet'))),
    re_path(r'^jet/dashboard/', include('jet.dashboard.urls', namespace='jet-dashboard')),
