Error running Django tutorial

[Mike Kipling]

I am working through the Django tutorial Writing your first Django app, part 1.

I am using Windows 10, python 3.5.1 and Django 1.9.2 .

 

In the Write your first view section: 

    after writing the polls/views.py and polls/urls.py files,

    and modifying the manage/urls.py file,

    and starting the server,

 

    When I go to http://localhost:8000/polls/ in the browser I get the following error:

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.

[James Schneider]

It doesn't appear that you've included your apps urls.py correctly using an include() in your project urls.py.

Can you post both of your urls.py files?

-James

[Mike Kipling]

Here are the two urls.py files:

polls/urls.py

from django.conf.urls import url

from . import views

urlpatterns = [

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

]

mysite/urls.py

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),

]

Mike, do you have the server restarted? 

As for me, the shell window says: 

Starting development server at http://127.0.0.1:8000/

Quit the server with CTRL-BREAK.

Igor,

Yes, the server was started.  Here are the contents of the command window including after trying to go to the website.

You have unapplied migrations; your app may not work properly until they are applied.

Run 'python manage.py migrate' to apply them.

Did you add 'polls' to your list of INSTALLED_APPS in your settings.py? After that you should run > python manage.py migrate like the terminal is suggesting to you.

[Mike Kipling]

Jorr,

No, I did not modify the settings.py file, because the tutorial specifically states: 

Note

Ignore the warning about unapplied database migrations for now; we’ll deal with the database shortly.

Here is a link to the tutorial: https://docs.djangoproject.com/en/1.9/intro/tutorial01/

[jorr...@gmail.com]

Well that's strange... The problem appears to be that your polls.urls file is not getting included in your project's URLConf (since the error message in your first post says that the only URL tried was admin/ ). I'm not sure if adding the app to INSTALLED_APPS is necessary for an app's URLConf to be able to be included, but it's worth a try. In FirstApp/settings.py add 'polls' to the list of INSTALLED_APPS so that it looks something like this:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'polls.apps.PollsConfig',
]

Otherwise it does seem like it could be a file refresh problem.

[Mike Kipling]

I added polls to settings.py :

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'polls.apps.PollsConfig',

]

Then I tried the migration:

C:\Data\Django_Code\FirstApp\mysite>python manage.py migrate

Operations to perform:

  Apply all migrations: admin, sessions, contenttypes, auth

Running migrations:

  No migrations to apply.

Then I started the server and tried going to the address, but got the same results:

C:\Data\Django_Code\FirstApp\mysite>python manage.py runserver

Performing system checks...

System check identified no issues (0 silenced).

I am working on a Windows OS, so I thought that perhaps changing the '/' in the mysite\urls.py to '\\' might help, but it did not.

[jorr...@gmail.com]

Can you attach your entire project's code in a ZIP file? I'm curious to test this myself...

[Mike Kipling]

I found the problem.

When the mysite\urls.py file is created, it has this line already in it.

from django.conf.urls import url

The tutorial asks you to add the following lines to the file.

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),

]

I must did not notice that the 'include' was different, and so I had not placed it into the file.  I changed the file to add the 'include' and everything worked.

Thank you for the help.

[jorr...@gmail.com]

Glad you got it solved!!

Hi,
I am getting the same problem, despite having include in my mysite\urls.py file.
I am using Python 2.7.6, Django 1.9.4 and Ubuntu 14.04.3 LTS.
Could it by a Python 2.7 problem?

Hi,

I am also facing the same problems with the djangoproject tutorial - I have changed the settings.py file to add the polls app, but it did not solve the issue:

When runserver: I get the admin page, but not the polls page. Get a similar 404 error page as Kipling, but with the ˆpolls/ url in the list.

Running in virtualenv - with python 3.5.2 and django 10.1.6 on Ubuntu 16.04. Any idea of what is wrong?

Here is my code:

# Your first view: opprettet polls/urls.py

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'ˆ$', views.index, name='index'),
]

# Your first view polls/views.py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hoppla, polls index her..")

# Site/urls.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'ˆpolls/', include('polls.urls')),
    url(r'^admin/', admin.site.urls),
]
# Site/settings.py
# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

Easy to see this way. You didn't type a caret but some unicode sign that looks like a caret.

Here is the error I keep getting. I've started this tutorial on python 3.6. I ran into the problems people had before. Somehow I've fixed them before I got here. I can't seem to reconcile this part. Any suggestions?

[Thomas Pittman]

Here is a copy of the the mysite.py file. I'm not sure how, but the error stopped after I imported imclude and polls this way.

Hi.

You may have a strange, non-visible character in your file just before the line giving error.

[Vijay Khemlani]

Why is there a backslash in

from django.conf.urls import polls\

?

Show the urls.py after adding everything. Note that there must be two urls.py. One in the project folder, another in the app folder

I have been testing this tutorial frequently over the last few days (with success) and am using an empty string ( ‘’ ) for the route (first argument to path) in the app’s urls.py, rather than the ‘raw’ string value I see in the earlier posts here.

I just wanna, explain my experience, in the official tutorial https://docs.djangoproject.com/en/2.1/intro/tutorial01/  when they tell you to edit urls file of mysite directorythey didnt mention which one. And in the beginning of tutorial our project name is also mysite, so i thought that I have to create new urls.py out side. but you have to to use inbuilld one. 

[kyle D]

I'm using Django for a class, and came across this thread and thought I'd post what fixed it for me in case someone else has the same issue I did.

Makes sure your mysite/urls.py is the one that has the urlpatterns[] with the path to your polls and not the mysite/polls/urls.py.

This one:

urlpatterns = [

    path('polls/', include('polls.urls')),

    path('admin/', admin.site.urls),

]

 

Not this one:

app_name = 'polls'

urlpatterns = [

    # ex: /polls/

    path('', views.index, name='index'),

[Thomas Pittman]

Kyle D,

This is why I stay in this thread. Thanks for the heads up. I remember being so lost when I tried to start teaching myself Django. What's the class for?

In in mysite/urls.py

check the "/" after "polls" in this line:

path('polls/', include('polls.urls'))
