Subject: Re: Removing Hardcoded urls in Templates
It should be {% url 'polls:detail' question.id %}
I think you mixed up the steps "Removing hardcoded URLs in templates" and
"Namespacing URL names"
Hope that helps,
Daniel

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
