Django：具有通用视图的 reverse_lazy()

Question

我有两个通用视图（CreateView 和 DetailView）。

在保存表单后的 CreateView 中，我想重定向到 DetailView 以显示我新创建的对象。

但发生错误：Reverse for 'questions.views.DisplayQuestions' not found. 'questions.views.DisplayQuestions' is not a valid view function or pattern name.

如何使用reverse_lazy 调用我的DetailView？

.views:

class DisplayQuestions(ListView):
    model = Question
    context_object_name = "all_questions"
    template_name = "questions/home.html"

    def get_queryset(self):
        return Question.objects.order_by(self.kwargs['display_type'])


@method_decorator(login_required, name='dispatch')
class CreateQuestion(CreateView):
    model = Question
    template_name = 'questions/nouveau.html'
    form_class = QuestionForm

    def get_success_url(self):
        return reverse_lazy(DisplayQuestion) # <-- This doesn't work !!!

    def form_valid(self, form):
        self.object = form.save(commit=False)
        self.object.profil = self.request.user.profil
        self.object = form.save()
        return HttpResponseRedirect(self.get_success_url())

.urls:

urlpatterns = [
    url(r'^nouveau$', views.CreateQuestion.as_view()),
    url(r'(?P<display_type>\w+)', views.DisplayQuestions.as_view()),]

.forms:

class QuestionForm(forms.ModelForm):

    class Meta:
        model = Question
        fields = ('question','categorie',)

您应该将配置中的每个 url 命名为，

urlpatterns = [
    url(r'^nouveau$', views.CreateQuestion.as_view(), name='create-question'),
    url(r'(?P&ltdisplay_type>\w+)', views.DisplayQuestions.as_view(), name='display-question'),
]

然后访问它，

return reverse_lazy(<b>'display-question', kwargs={'display_type': 'your-display-type-value'}</b>)
