when my django app try to access the undermentioned URL:
path('quiz/confirm/<int:pk>/', suppliers.QuizUpdateView.as_view(), name='quiz_change'),
it shows NoReverseMatch error. I am unable to figure out where this is coming from. Should I add the traceback too ?
This is the template in QuizUpdateView:
<nav aria-label="breadcrumb">
<ol class="breadcrumb">
<li class="breadcrumb-item"><a href="{% url 'suppliers:quiz_change_list' %}">My Quizzes</a></li>
<li class="breadcrumb-item"><a href="{% url 'suppliers:quiz_change' activetruck.pk %}">{{ quiz.name }}</a></li>
<li class="breadcrumb-item active" aria-current="page">Results</li>
</ol>
</nav>
<h2 class="mb-3">{{ quiz.name }} Results</h2>
<div class="card">
<div class="card-header">
<strong>Posted Requests For Quotes</strong>
<span class="badge badge-pill badge-primary float-right">Least Bid: {{ quiz_score.least_bid|default_if_none:0.0 }}</span>
</div>
<table class="table mb-0">
<thead>
<tr>
<th>supplier</th>
<th>Date</th>
<th>Bid Amount</th>
</tr>
</thead>
<tbody>
{% for taken_quiz in taken_quizzes %}
<tr>
<td>{{ taken_quiz.supplier.user.username }}</td>
<td>{{ taken_quiz.date|naturaltime }}</td>
<td>{{ taken_quiz.least_bid }}</td>
</tr>
{% endfor %}
</tbody>
</table>
<div class="card-footer text-muted">
Total respondents: <strong>{{ total_taken_quizzes }}</strong>
</div>
</div>
I suppose the error is in the template file as I have already checked the code thoroughly
