Running Django 3.0 & Python 3.7.3.
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 %}
