Django - The included urlconf doesn't have any patterns in it

Question

My website, which was working before, suddenly started breaking with the error

ImproperlyConfigured at / The included urlconf resume.urls doesn't have any patterns in it

The project base is called resume. In settings.py I have set

ROOT_URLCONF = 'resume.urls'

Here's my resume.urls, which sits in the project root directory.

from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Example:
    # (r'^resume/', include('resume.foo.urls')),

    # Uncomment the admin/doc line below and add 'django.contrib.admindocs' 
    # to INSTALLED_APPS to enable admin documentation:
    (r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    (r'^admin/', include(admin.site.urls)),

    (r'^accounts/login/$', 'django.contrib.auth.views.login'),


    #(r'^employer/', include(students.urls)),

    (r'^ajax/', include('urls.ajax')),
    (r'^student/', include('students.urls')),
    (r'^club/(?P<object_id>\d+)/$', 'resume.students.views.club_detail'),
    (r'^company/(?P<object_id>\d+)/$', 'resume.students.views.company_detail'),
    (r'^program/(?P<object_id>\d+)/$', 'resume.students.views.program_detail'),
    (r'^course/(?P<object_id>\d+)/$', 'resume.students.views.course_detail'),
    (r'^career/(?P<object_id>\d+)/$', 'resume.students.views.career_detail'),

    (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'C:/code/django/resume/media'}),

)

I have a folder called urls and a file ajax.py inside. (I also created a blank init.py in the same folder so that urls would be recognized.) This is ajax.py.

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    (r'^star/(?P<object_id>\d+)$', 'resume.students.ajax-calls.star'),
)

Anyone know what's wrong? This is driving me crazy.

Thanks,

Answer 1

In my case, i was using a class based view UpdateView and in sucess_url attribute i was passing

sucess_url = redirect(reverse('my url name'))

But it break the code, because for some reason behind the scenes Django already make a redirect giving a error of "urlpatterns failed or circular import".

For solve this just remove redirect function and your code will work normally

sucess_url = reverse('your url name')

Answer 2

Yet another possible cause for this type of error is the improper use of reverse() or reverse_lazy().

For example, if you inadvertently confuse the signature of reverse with that of the url tag, and do something like this

reverse('my_view_name', 123)

then you'll see

The included URLconf '123' does not appear to have any patterns in it.

That should be something like

reverse('my_view_name', args=[123])

Answer 3

django.urls.reverse() to django.urls.reverse_lazy() This will instantly solve it.

Answer 4

In my case using comma at the end of path in App's urls.py solved the issue.

example:-

urlpatterns =[
    path('', views.index, name='app')**,**
]

stars in the code are for highlighting the comma only.

Answer 5

django.urls.reverse()-->django.urls.reverse_lazy() This will instantly solve it.

Answer 6

Check the name of the variable.

The cause of my error was using "urlspatterns" in lieu of "urlpatterns".

Correcting the name of the variable solved the issue for me.

Answer 7

In my case, it was because of tuple unpacking. I only had one url and the root cause for this ImproperlyConfigured error was

TypeError: 'URLPattern' object is not iterable

I used a trailing comma at the end and it resolved the issue.

urlpatterns = (url(...) , )

Answer 8

Check the imported modules in views.py if there is any uninstalled modules you found remove the module from your views.py file. It's Fix for me

Answer 9

check for correct variable name in your app, if it is "

urlpatterns

" or any thing else. Correcting name helped me

Answer 10

Note: For some reason, for me this error also went away after I saved another file. So the first time the error appeared, I had saved a file in which I specified the wrong widget in the forms.py file:

extra_field = forms.CharField(widget=forms.TextField())

instead of

extra_field = forms.CharField(widget=forms.TextInput()) 

After changing it to the correct version (TextInput) and saving the forms.py file, the error was still showing in my console. After saving another file (e.g. models.py) the error disappeared.

Answer 11

In my case I had the following error:

ImproperlyConfigured: The included URLconf does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

The url patterns were valid, but the problem was an Import error caused by a typo. I typed restframework instead of rest_framework.

Answer 12

TL;DR: You probably need to use reverse_lazy() instead of reverse()

If your urls.py imports a class-based view that uses reverse(), you will get this error; using reverse_lazy() will fix it.

For me, the error

The included urlconf project.urls doesn't have any patterns in it

got thrown because:

• project.urls imported app.urls
• app.urls imported app.views
• app.views had a class-based view that used reverse
• reverse imports project.urls, resulting in a circular dependency.

Using reverse_lazy instead of reverse solved the problem: this postponed the reversing of the url until it was first needed at runtime.

Moral: Always use reverse_lazy if you need to reverse before the app starts.

Answer 13

I got this error when trying to reverse (and reverse_lazy) using RedirectView and parameters from the url. The offending code looked like this:

from django.views.generic import RedirectView
from django.core.urlresolvers import reverse
url(r'^(?P<location_id>\d+)/$', RedirectView.as_view(url=reverse('dailyreport_location', args=['%(location_id)s', ]))),

The fix is to use this url in urlpatterns:

from django.views.generic import RedirectView
url(r'^(?P<location_id>\d+)/$', RedirectView.as_view(url='/statistics/dailyreport/%(location_id)s/')),

ANSWER: The fix so you can still use the name of the url pattern:

from django.core.urlresolvers import reverse
from django.http import HttpResponseRedirect
urlpatterns = patterns('',
    ....
    url(r'^(?P<location_id>\d+)/$', lambda x, location_id: HttpResponseRedirect(reverse('dailyreport_location', args=[location_id])), name='location_stats_redirect'),
    ....
)

Answer 14

IN my case I got this error during deployment. Apache kept giving me the "AH01630: client denied by server configuration" error. This indicated that was wrong with apache configuration. To help troubleshoot I had turned on Debug=True in settings.py when I saw this error.

In the end I had to add a new directive to the static files configuration inside apache config. When the static files were not accessible and Debug in django settings was set to true this error was getting triggered somehow.

Answer 15

Check your patterns for include statements that point to non-existent modules or modules that do not have a urlpatterns member. I see that you have an include('urls.ajax') which may not be correct. Should it be ajax.urls?
