Django view에서의 사용법

• Function based view 일 경우

  • 방법 1

  @login_required
  def post_create(request):
      return render(request, 'core/index.html')

  • 방법 2

  def post_create(request):
      return render(request, 'core/index.html')
  
  post_create = login_required(post_create)

• Class based view 일 경우

  • 방법 1 : as_view -> 함수로 감싸주기

  class MyTemplateView(TemplateView):
      template_name= "core/index.html"
  
  index = MyTemplateView.as_view()
  index = login_required(index)

  • 방법 2 : method_decorator를 함수에 적용

  class MyTemplateView(TemplateView):
      template_name= "core/index.html"
  
      @method_decorator(login_required)
      def dispatch(self, *args, **kwargs):
      return super().dispatch(*args, **kwargs)
  
  index = MyTemplateView.as_view()

  • 방법 3 : method_decorator을 클래스에 적용

  @method_decorator(login_required, name="dispatch")
  class MyTemplateView(TemplateView):
      template_name= "core/index.html"
  
  index = MyTemplateView.as_view()
