[RESOLVED] --was: Re: application not recognized as URL namespace

I see my error: 'auth' is already an appname (django.contrib.auth).

Using 'accnt' works perfectly!

Thanks, again, Axel

authentication/urls.py:

 

from django.conf.urls import url
from . import views

 

app_name = 'authentication'

I thought you didn't have an app_name, but you do have one.

I changed this after your advice.

In that case, the only problem was that you passed the wrong urlconf to reverse(). You should be able to reverse the url with:

reverse('authentication:password_change')

I did not try this combination, but it works!  Thanks!

One last question:

Changing this to an instance namespace would just require in urls:

    url(r'^auth/', include('authentication.urls', namespace='auth')),

and where I reverse:

        reverse('auth:password_change')

right?

But this again gives:

django.core.urlresolvers.NoReverseMatch: 'auth' is not a registered namespace

Could you show your full root urls.py and authentication/urls.py?

urls.py:

from django.conf.urls import include, url

from django.views.generic import TemplateView

# Uncomment the next two lines to enable the admin:

from django.contrib import admin

urlpatterns = (

    url(r'^$', TemplateView.as_view(template_name='base.html')),

    url(r'^authentication/', include('authentication.urls')),

    url(r'^admin/', include(admin.site.urls)),

)

if settings.DEBUG:

    import debug_toolbar

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

authentication/urls.py:

from django.conf.urls import url

from . import views

app_name = 'authentication'

urlpatterns = [

    url(r'^$', views.index, name='index'),

    url(r'^login/$', views.login, name='login'),

    url(r'^loggedin/$', views.loggedin, name='loggedin'),

    url(r'^logout/$', views.logout, name='logout'),

    url(r'^password/$', views.password, name='password'),

    url(r'^password_change/$', views.password_change, name='password_change'),

    url(r'^password_change/done/$', views.password_change_done, name='password_change_done'),

    url(r'^password_reset/$', views.password_reset, name='password_reset'),

    url(r'^password_reset/done/$', views.password_reset_done, name='password_reset_done'),

    url(r'^reset/done/$', views.password_reset_complete, name='password_reset_complete'),

    url(r'^reset/(?P<uidb64>[0-9A-Za-z]{1,13})-(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',

        views.password_reset_confirm,

        name='password_reset_confirm'),

    url(r'^profile/$', views.profile, name='profile')

]

Hi Axel,

An installed application and a registered URL namespace are two distinct concepts. A URL namespace can only be defined by setting the app_name attribute in your urlconf. In this case, you haven't set a URL namespace for your authentication app, so your urls are not namespaced.

OK. (I misunderstood the 1.9 docu as this would be required only with instance namespaces).

Also, the urlconf parameter to reverse() should point to the root urlconf, not to the urlconf in which your current url is defined. Since it defaults to the root urlconf defined in your project, it's easiest to omit it in most cases. If you don't, and use 'authentication.urls' as your root urlconf, the generated url will miss the 'authentication/' part of your url.

I understand.

 

To reverse the password_change url, simply use this:

reverse(‚password_change')

Making both changes gives:

django.core.urlresolvers.NoReverseMatch: Reverse for 'password_change' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

I then tried to reference the views directly instead of strings:

from . import views

reverse(views.password_change),

with views.py containing:

    class PasswordChangeView(LoginRequiredMixin, AuthDecoratorsMixin, WithCurrentSiteMixin, FormView):

        ...

        

    password_change = PasswordChangeView.as_view()

and got;

django.core.urlresolvers.NoReverseMatch: Reverse for 'authentication.views.PasswordChangeView' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

In my root url, I have:

in authentication/urls.py, I have no app_name declared.

In a module in authentication, I have

        from django.core.urlresolvers import reverse

        from django.apps import apps
        print('authentication installed? ' + str(apps.is_installed('authentication')))

        reverse('authentication:password_change',urlconf='authentication.urls')
 
and receive
        django.core.urlresolvers.NoReverseMatch: 'authentication' is not a registered namespace
while the above debug print gives
        authentication installed? True

What am I doing wrong here?

Please advice,
Axel
