公式チュートリアルからdjangoを学ぼうとしています。
私は奇妙な問題で立ち往生しています。それは些細なことかもしれませんが、私はそれを理解することができません -
私はこのチュートリアルに従っています：
私の問題は、にアクセスしようとするとhttp://hello.djangoserver:8080/poll、次の出力が得られることです。
しかし、出力は object の値である必要があります。何が問題なのかわかりません?? チュートリアルで説明されている以前のすべての手順は、私にとってはうまく機能しています。
コンソール出力は次のとおりです。
(InteractiveConsole)
>>> from poll.models import Question, Choice
>>> Question.objects.get(pk=1)
<Question: What's up?>
>>> quit()

from django.template import RequestContext, loader
from poll.models import Question
def index(request):
latest_question_list = Question.objects.order_by('-pub_date')[:5]
template = loader.get_template('poll/index.html')
context = RequestContext(request, {
'latest_question_list': latest_question_list,
})
return HttpResponse(template.render(context))
def detail(request, question_id):
return HttpResponse("You're looking at question %s." % question_id)
def results(request, question_id):
response = "You're looking at the results of question %s."
return HttpResponse(response % question_id)
def vote(request, question_id):
return HttpResponse("You're voting on question %s." % question_id)
