Django：reverse_lazy（）与通用视图

Question

我有两个通用视图（“创建视图”和“详细信息视图”）。

在我的创建视图中，保存我的窗体后，我想重定向到详细信息视图以显示我新创建的对象。

但是发生了一个错误：Reverse for 'questions.views.DisplayQuestions' not found. 'questions.views.DisplayQuestions' is not a valid view function or pattern name.

如何通过reverse_lazy调用我的详细信息视图？

.视图：

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())

.网址：

urlpatterns = [

    url(r'^nouveau$', views.CreateQuestion.as_view()),

    url(r'(?P<display_type>\w+)', views.DisplayQuestions.as_view()),]

.形式：

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 = [&nbsp; &nbsp; url(r'^nouveau$', views.CreateQuestion.as_view(), name='create-question'),&nbsp; &nbsp; url(r'(?P<display_type>\w+)', views.DisplayQuestions.as_view(), name='display-question'),]然后访问它，return reverse_lazy('display-question', kwargs={'display_type': 'your-display-type-value'})
