第4课: NoReverseMatch at /enquete/2/

Question

我有以下错误

相反的‘表决’与论点'(2，)‘找不到。已尝试的1个模式：['enquete\/\‘

这是我的回溯

[02/Mar/2019 17:18:39] "GET /enquete/2/ HTTP/1.1" 500 112049
^C%  

这是我的观点，view.py

 class DetailView(generic.DetailView):
      model = Question
      template_name = 'enquete/detail.html'

这是我的网址，url.py

  app_name = 'enquete'
  urlpatterns = [
      path('',views.IndexView.as_view(), name='index'),
      path('<int:pk>/',views.DetailView.as_view(),name='detail'),
      path('<int:pk>/results',views.ResultsView.as_view(),name='results'),
      path('<int:question_id/vote/',views.vote,name='vote'),
 ]

这是我的模板，detail.html

<h1> {{ question.question_text }} </h1>

{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}
<form action="{% url 'enquete:vote' question.id %}" method="get">
{% csrf_token %}
{% for choice in question.choice_set.all %}
    <input type="radio" name="choice" id="choice {{forloop.counter}}" value="{{choice.id}}">
    <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br>
{% endfor %}    
<input type="submit" value="Vote">
</form>

我需要在我的模型中增加投票吗？如果是的话怎么做。我对下一步该做什么很有信心。

谢谢。

您有错误的url路径，请更正如下。Missplaced >

path('<int:question_id>/vote/',views.vote,name='vote'),
