找不到参数为‘(’，)‘’的'single_quiz‘在/ NoReverseMatch /test/ Reverse处的测试。1个已尝试的模式：[‘测验/(？P<quiz_id>[0-9]+)/$’]

Question

传递id时发生反向匹配错误。但当添加的manually.it显示NoReverseMatch错误时，工作正常。我不知道这是从哪里来的。我也应该添加回溯吗？

尝试使用这个:-

    {% for a in quiz %}


    <a href="{% url 'single_quiz' a.id %}">{{a.job.quiz}}</a>
    
    {% endfor %}

我在你的整个视图中没有看到任何名为applied的变量。确保您成功地传递了所有变量。
