404 오류 처리

Http404 를 처리할 때는 loader-render 관계처럼 단축 함수가 존재 한다.

 

get_object_or_404

 

from django.shortcuts import render, get_object_or_404

def detail(request, question_id):
    # try:
    #     question = Question.objects.get(pk=question_id)
    # except Question.DoesNotExist:
    #     raise Http404("Question does not exist")
    
    question = get_object_or_404(Question, pk=question_id)
    # return HttpResponse("You're looking at question %s." % question_id)
    return render(request, 'polls/detail.html', {'question': question})
