Re: Following tutoria: View not defined

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.

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),
]
