Error with Tutorial - Writing your first Django app, part 1

[Johnny McClung]

I am getting an error when I try to run the Django server.

urlpatters = [

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

from django.conf.urls import include, url

from django.contrib import admin

urlpatterns = [

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

    url(r'^admin/', admin.site.urls),

]

Any help would be appreciated. Thank you. 

[Tim Graham]

Add a comma after: url(r'^polls/', include('polls.urls'))
(these are items in a list, separated by a comma)

Thank you. I've added the comma as you mentioned. Can't believe I missed that. But now I am getting a new error.

[Dylan Reinhold]

In polls/url.py patterns is missing the N.

Hi, I am facing the same issue with the tutorial.

I have got my program correct. But after running the sever. It shows an error on chrome.

Page not found (404)

Request Method:	GET
Request URL:	http://localhost:8000/polls/

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

1. ^admin/

The current URL, polls/, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

Since this is first ste of tutorial. I am not able to move forward. Thanx for rely in advance.

Missing comma on you urlpatterns

urlpatterns = [

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

    url(r'^admin/', admin.site.urls),

]

Shah,

Did you get this figured out? I am having the same issue as you did.

[Vijay Khemlani]

In the first case he mispelled "urlpatters", it should be "urlpatterns" (notice the n)

Lynn, you should really start your own thread. If you have an error, copy/paste it entirely, this make debugging a lot easier. And don't​ hesitate to share your code.

There is a lot of things that can go wrong when we begin and most give more or less the same result.

[Talha Imran]

this is my urlpattern code:

urlpatterns = [
path(' ', include('calc.urls')),
path('admin/', admin.site.urls),
]

And I am facing this error and i don't know what this error is:

python manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

Exception in thread django-main-thread:

The above exception was the direct cause of the following exception:
