[1.1.X] Fixed #11959 -- Updated the tutorial to ensure that the admin site...

    polls/

        __init__.py

        models.py

        tests.py

        views.py

This directory structure will house the poll application.

    * Run ``python manage.py syncdb``. Since you have added a new application

      to :setting:`INSTALLED_APPS`, the database tables need to be updated.

    * Edit your ``mysite/urls.py`` file and uncomment the lines below the

      "Uncomment the next two lines..." comment. This file is a URLconf;

      we'll dig into URLconfs in the next tutorial. For now, all you need to

      know is that it maps URL roots to applications. In the end, you should

      have a ``urls.py`` file that looks like this:

    * Edit your ``mysite/urls.py`` file and uncomment the lines that reference

      the admin -- there are three lines in total to uncomment. This file is a

      URLconf; we'll dig into URLconfs in the next tutorial. For now, all you

      need to know is that it maps URL roots to applications. In the end, you

      should have a ``urls.py`` file that looks like this:

    .. versionchanged:: 1.1

        The method for adding admin urls has changed in Django 1.1.

This is the simplest view possible. Go to "/polls/" in your browser, and you

should see your text.

Now add the following view. It's slightly different, because it takes an

argument (which, remember, is passed in from whatever was captured by the

regular expression in the URLconf)::

Now lets add a few more views. These views are slightly different, because

they take an argument (which, remember, is passed in from whatever was

captured by the regular expression in the URLconf)::

    def detail(request, poll_id):

        return HttpResponse("You're looking at poll %s." % poll_id)

Take a look in your browser, at "/polls/34/". It'll display whatever ID you

provide in the URL.

    def results(request, poll_id):

        return HttpResponse("You're looking at the results of poll %s." % poll_id)

    def vote(request, poll_id):

        return HttpResponse("You're voting on poll %s." % poll_id)

Take a look in your browser, at "/polls/34/". It'll run the `detail()` method

and display whatever ID you provide in the URL. Try "/polls/34/results/" and

"/polls/34/vote/" too -- these will display the placeholder results and voting

pages.

Write views that actually do something

======================================

``mysite/urls.py`` to remove the poll-specific URLs and insert an

:func:`~django.conf.urls.defaults.include`::

    ...

    # ...

    urlpatterns = patterns('',

        (r'^polls/', include('mysite.polls.urls')),

        ...

        # ...

:func:`~django.conf.urls.defaults.include`, simply, references another URLconf.

Note that the regular expression doesn't have a ``$`` (end-of-string match

    (r'^(?P<poll_id>\d+)/vote/$', 'vote'),

So let's create a ``vote()`` function in ``mysite/polls/views.py``::

We also created a dummy implementation of the ``vote()`` function. Let's

create a real version. Add the following to ``mysite/polls/views.py``::

    from django.shortcuts import get_object_or_404, render_to_response

    from django.http import HttpResponseRedirect

    from django.http import HttpResponseRedirect, HttpResponse

    from django.core.urlresolvers import reverse

    from mysite.polls.models import Choice, Poll

    # ...
