無法訪問 Django 中的 UpdateView

Question

更新（在此處輸入圖片描述我在 url 中添加了反斜杠並出現了新錯誤）我的想法是讓老師和學生在一起，我希望我的老師能夠在我嘗試訪問時出於某種原因為學生編輯測驗通過其他 ListView 的 QuizUpdateView 它給了我 404 Not Found截圖所以我想用這個視圖編輯我的測驗：

class QuizUpdateView(views.UpdateView):
model = Quiz
fields = ('name', 'subject', )
context_object_name = 'quiz'
template_name = 'classroom/quiz_update.html'

def get_context_data(self, **kwargs):
    kwargs['questions'] = 
self.get_object().questions.annotate(answers_count=Count('answers'))
    return super().get_context_data(**kwargs)

def get_queryset(self):
    return self.request.user.quizzes.all()

def get_success_url(self):
    return reverse_lazy('quizzes')

我的 urls.py 中有 int:pk

urlpatterns = (
path('register', RegisterView.as_view(), name='register'),
path('register/student', StudentRegisterView.as_view(), name='register student'),
path('register/register', TeacherRegisterView.as_view(), name='register teacher'),
path('login', LoginView.as_view(), name='login'),
path('logout', LogoutView.as_view(), name='logout'),
path('quizzes', QuizListView.as_view(), name='quizzes'),
path('quiz/create', QuizCreateView.as_view(), name='create quiz'),
path('quiz/update/<int:pk>', QuizUpdateView.as_view(), name='update quiz'),
)

我在模板中也有 quiz.pk（我嘗試使用 quiz.id，結果相同）

{% extends 'base.html' %}

{% block page_content %}
{% include 'classroom/student_header.html' with active='new' %}
<div class="card">
    <table class="table mb-0">
        <thead>
        <tr>
            <th>Quiz</th>
            <th>Subject</th>
            <th>Length</th>
            <th></th>
        </tr>
        </thead>
        <tbody>
        {% for quiz in quizzes %}
            <tr>
                <td class="align-middle">{{ quiz.name }}</td>
                <td class="align-middle">{{ quiz.subject.get_html_badge }}</td>
                <td class="align-middle"> questions</td>
                <td class="text-right">
                    {% if request.user.type == 'Student' %}
                        <a href="" class="btn btn-primary">Start quiz</a>
                    {% elif request.user.type == 'Teacher' %}
                        
                        <a href="{% url 'update quiz' quiz.pk %}" class="btn btn- 
         warning">Edit quiz</a>
                        <a href="" class="btn btn-warning">Delete quiz</a>
                        
                    {% endif %}
                </td>
            </tr>
        {% empty %}
            <tr>
                <td class="bg-light text-center font-italic" colspan="4">No exam 
                matching your interests right
                    now.
                </td>
            </tr>
        {% endfor %}
        </tbody>
    </table>
</div>
{% endblock %}

這是model

class Quiz(models.Model):
owner = models.ForeignKey(UniversityUser, on_delete=models.CASCADE, 
related_name='quizzes')
name = models.CharField(max_length=QUIZ_NAME_MAX_LENGTH, unique=True)
subject = models.ForeignKey(Subject, on_delete=models.CASCADE, 
related_name='quizzes')

def __str__(self):
    return self.name

這是我用於 UpdateView 的模板：

{% extends 'base.html' %}

{% block page_content %}
<h2 class="mb-3">
    {{ quiz.name }}
    <a href="{% url 'teachers:quiz_results' quiz.pk %}" class="btn btn-primary float- 
right">View results</a>
</h2>
<div class="row mb-3">
    <div class="col-md-6 col-sm-8 col-12">
        <form method="post" action="{% url 'update quiz' quiz.pk %}">
            {% csrf_token %}
            {{ form.as_p }}
            <button type="submit" class="btn btn-success">Save changes</button>
            <a href="{% url 'quizzes' %}" class="btn btn-outline-secondary" 
 role="button">Nevermind</a>
            <a href="" class="btn btn-danger float-right">Delete</a>
        </form>
    </div>
</div>
<div class="card">
    <div class="card-header">
        <div class="row">
            <div class="col-10">
                <strong>Questions</strong>
            </div>
            <div class="col-2">
                <strong>Answers</strong>
            </div>
        </div>
    </div>
    <div class="list-group list-group-flush list-group-formset">
        {% for question in questions %}
            <div class="list-group-item">
                <div class="row">
                    <div class="col-10">
                        <a href="">{{ question.text }}</a>
                    </div>
                    <div class="col-2">
                        {{ question.answers_count }}
                    </div>
                </div>
            </div>
        {% empty %}
            <div class="list-group-item text-center">
                <p class="text-muted font-italic mb-0">You haven't created any 
  questions yet. Go ahead and <a
                        href="">add the first question</a>.</p>
            </div>
        {% endfor %}
    </div>
    <div class="card-footer">
        <a href="" class="btn btn-primary btn-sm">Add question</a>
    </div>
</div>
{% endblock %}

如果您對發生這種情況的原因有任何想法，請發表評論，謝謝：:)

我不確定但是你繼承的 class 是對的嗎？ 嘗試導入：

from django.views.generic.edit import UpdatView

class QuizUpdateView(UpdateView):
