Django-如何在基于类的视图方法中使用decorator？

Question

我正在开发一个网站与django 1.8。以下是其中一个视图的示例：

class ProfileView(View):
    template_name = 'index.html'

    # Return profile of any role (client/employee/admin)
    # Login required
    def get(self, request, *args, **kwargs):
        try:
            profile = Profile.objects.get(user=request.user)
            agency = None

            if request.user.is_employee():
                employee = EmployeeProfile.objects.get(profile=profile)
                agency = employee.agency

            if request.user.is_manager():
                agency = Agency.objects.get(manager=request.user)

        except (Profile.DoesNotExist, EmployeeProfile.DoesNotExist, Agency.DoesNotExist) as e:
            return HttpResponseRedirect('/404')

        return render(request, self.template_name, {"profile": profile, "agency": agency})

    # Client sign up
    # No decorator is needed
    def post(self, request):
        sign_up = SignUpForm(request.POST, request.FILES)

        response = json.loads(utils.create_user(sign_up,request.POST['avatar']))
        if response['profile'] is None:
            return JsonResponse({"code": 400, "response": response['message']})
        profile = serializers.deserialize("json", response['profile']).next().object

        group = Group.objects.get(name='clients')
        profile.user.groups.add(group)

        return HttpResponseRedirect('/')

问题是，我可以根据对控制器（视图）的请求类型使用不同的装饰器吗？

您需要将decorator应用于基于类的视图的分派方法。具体操作如下：

class ProfileView(View):

    @youdecorator
    def dispatch(self,request,*args,**kwargs):
        return super(ProfileView,self).dispatch(request,*args,**kwargs)
    //Rest of your code.
