Error in the Django tutorial: urls.py

Question

I just upgraded my Django to version 1.9.6. I was doing the basic tutorial but I have a Syntax Error in the urls.py.

Note: I changed the name "mysite" to "polls", and "polls" to "poll".

This is my code in polls/poll/urls.py:

from django.conf.urls import url

from . import views

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

And this is the error message:

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x03AE16F0>

Thanks for the help

You have missed out the ' to end the string (before the comma in r'^,. Ideally, you should add a $ as well:

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

Note that your text editor or IDE may do syntax highlighting to help you spot this question - note that in your question, Stack Overflow has all of ^, views.index, name= in the same colour, to show that it's a single string.

Thank you very much @Alasdair. But now I'm getting this message: """" Page not found (404) Request Method: GET Request URL: 127.0.0.1:8000 Using the URLconf defined in polls.urls, Django tried these URL patterns, in this order: ^poll/ ^admin/ The current URL, , 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. """ Your answer makes sense, but I only copied and pasted.

That 404 is expected. You haven't defined a url for / yet, you defined it for /poll/ (because of the include). The tutorial tells you to go to http://localhost:8000/polls/, not http://localhost:8000. In your case, go to http://localhost:8000/poll/, or change the include to ^polls/'.

Of course!, thank you very much @Alasdair. You saved me hours.
