    url(r'^$',
        ListView.as_view(
            queryset=Poll.objects.order_by('-pub_date')[:5],
            context_object_name='latest_poll_list',
            template_name='polls/index.html')),

Here you are setting template_name='polls/index.html'

 

TemplateDoesNotExist at /polls/

index.html, polls/poll_list.html

But this error corresponds to having set template_name='index.html' in this same view.

Review you really have set  template_name='polls/index.html' in that view and that this file is in place:

/home/my_user/Webdev/Templates/polls/index.html

 Cheers

Let's see the whole error page.

Thank you for your input guys. 

Sadly, i had already checked it Carlos and have my templates for polls under:

/home/my_user/Webdev/Templates/polls

In this case my template dir is set up as:

/home/my_user/Webdev/Templates/

Should i create another polls dir under templates (/home/my_user/Webdev/Templates/polls/polls) considering in the error message i get 'polls/poll_list.html' , besides 'index.html'? This seems redundant and i'd like to understand why i would have to. 

Thanks again for your help.

While everything was working properly using custom views, i can't seem to make my app load the correct templates after switching to generic views.

Here's the code:

#urls.py
from django.conf.urls import patterns, include, url
from django.views.generic import DetailView, ListView
from polls.models import Poll

urlpatterns = patterns('',

    url(r'^$',
        ListView.as_view(
            queryset=Poll.objects.order_by('-pub_date')[:5],
            context_object_name='latest_poll_list',
            template_name='polls/index.html')),

    url(r'^(?P<pk>\d+)/$',
        DetailView.as_view(
            model=Poll,
            template_name='polls/detail.html')),
    url(r'^(?P<pk>\d+)/results/$',
        DetailView.as_view(
            model=Poll,
            template_name='polls/results.html'),
        name='poll_results'),
    url(r'^(?P<poll_id>\d+)/vote/$', 'polls.views.vote'),
)

The way i decided (perhaps wrongly) to organize my apps and templates is as follows:

Template dir as defined in settings.py:
TEMPLATE_DIRS = ('/home/my_user/Webdev/Templates/', # this is where i'm storing my templates at the moment

App location: /home/my_user/Webdev/Django-lessons/pollproject/polls

If i try to access the polls app directly by using the URL: http://127.0.0.1:8000/polls/ i now get an error message stating that:

TemplateDoesNotExist at /polls/

index.html, polls/poll_list.html

Oddly, when i started up the server this morning i could now see the polls correctly, while not having changed my code, by accessing http://127.0.0.1:8000/polls. Don't know if Django is prone to such randomness but am happy that it works now. Tested everything, added a view so that http://127.0.0.1:8000 loads polls, voted and viewed results. All fine.

I'll carry on testing this and getting a couple more tutorials done before moving to my first django production.

Thank you for your time and patience Carlos, much appreciated.

[Carlos Palol]

I'm glad.

Not very prone to randomness, actually. Make sure the web server is restarting after your changes, and that the browser cache is not lying to you.

Also, if you are changing module (file) names, better delete the .pyc files.

Cheers,

Sometimes the browser cache is making trouble too. Especially with Firefox I occasionally have this kind of problems. Clear the browser cache, or test with a different browser mostly helps.
