1. [https://docs.djangoproject.com/en/dev/intro/tutorial03/#writing-more-
views Writing more views] introduces `polls.views.detail` code that is
testable with `runserver`:
{{{
def detail(request, poll_id):
return HttpResponse("You're looking at poll %s." % poll_id)
}}}
2. Then,
[https://docs.djangoproject.com/en/dev/intro/tutorial03/#raising-a-404-error
Raising 404 error] introduces a new version of this view:
{{{
def detail(request, poll_id):
try:
poll = Poll.objects.get(pk=poll_id)
except Poll.DoesNotExist:
raise Http404
return render(request, 'polls/detail.html', {'poll': poll})
}}}
(Which you cannot test yet because you don't have `polls/detail.html`)
3. Then, this view code changes in
[https://docs.djangoproject.com/en/dev/intro/tutorial03/#a-shortcut-get-
object-or-404 A shortcut: get_object_or_404].
4. Then, and only then, the tutorial makes you create `polls/details.html`
in [https://docs.djangoproject.com/en/dev/intro/tutorial03/#use-the-
template-system Use the template system].
I think it's a problem that you code something in step 2., change it in
step 3., but are able to test it only after step 4. Shouldn't the app be
run-able at every step ?
