Re: Following tutoria: View not defined

Okkk. From your url pattern, What you should do is http://127.0.0.1:8000/hello. Because your url pattern says r'^hello/$'

But what u are doing presently is 

http://127.0.0.1:8000/

In this case your url pattern is supposed to be r'^$' and not r'^hello/$'

Hi all

I see that I missed the import.

I now have

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

from mysite.views import hello

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello/$', hello),
]

But get the following error in my browser now

Page not found (404)

Request Method:	GET
Request URL:	http://127.0.0.1:8000/

      Using the URLconf defined in mysite.urls,

      Django tried these URL patterns, in this order:

1. ^admin/
                  
   
2. ^hello/$
   

        The empty path 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.

I am totally new to Django, and working through the following tutorial https://djangobook.com/views-urlconfs/

Ihavecreatddf the following view in views.py

from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello world")

 And then as per the tutorial updated urls.py as follows:

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

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello/$', hello),
]

 When I try an browse http://127.0.0.1:8000/ I now no can no longer connect and the console shows the following error.
