Would you please replace url name with 'polls:detail', as described at 
https://docs.djangoproject.com/en/3.0/topics/http/urls/#id5

 


Saygılarımla,

Issue with Tutorial Part 3:
I replaced “<li><a href="/polls/{{ question.id }}/">{{ question.question_text 
}}</a></li>” with
“<li><a href="{% url 'detail' question.id %}">{{ question.question_text 
}}</a></li>” and get the following error:
Reverse for 'detail' not found. 'detail' is not a valid view function or 
pattern name.
<li><a href="{% url 'detail' question.id %}">{{ question.question_text 
}}</a></li>
index.html:
{% if latest_question_list %}

    <ul>

    {% for question in latest_question_list %}

        {% comment %} <li><a href="/polls/{{ question.id }}/">{{ question.id }} 
{{ question.question_text }} {{ question.pub_date }}</a></li> {% endcomment %}

        <li><a href="{% url 'detail' question.id %}">{{ question.question_text 
}}</a></li> {% comment %} - Why doesn't this work?-->  {% endcomment %}

    {% endfor %}

    </ul>

{% else %}

    <p>No polls are available.</p>

{% endif %}
