Tutorial03 makes you refactor code that you cannot run

[James Pic]

1. ​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, ​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 ​A shortcut: get_object_or_404.

4. Then, and only then, the tutorial makes you create polls/details.html in ​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 ?

Well, below [1] it does say:

We’ll discuss what you could put in that polls/detail.html template a bit later, but if you’d like to quickly get the above example working, just:

{{ poll }}

will get you started for now.

What's your suggestion for how to improve it?

I might change

"working, just:"

to

"working, a file containing just:"

But otherwise - yes, you can't cover everything simultaneously.

I made the small clarification - going to close as needs info, if the ticket author can provide some other concrete suggestions for improvement, by all means - please reopen.
