(i have 3 questions in database , id's 5,6,7 because have been deleting , adding questions.)
my admin works fine!
i'm new django , have been searching , asking around , have been stuck on while now.
you 404 on http://127.0.0.1:8000/ because have not created url patterns url. have included url http://127.0.0.1:8000/polls/, because have included polls urls with
url(r'^polls/',include('polls.urls')), the empty bullets suggest there problem polls/index.html template. looks have typo , have put {{ question.question_test }} instead of {{ question.question_text }}. make sure matches template tutorial 3:
{% if latest_question_list %} <ul> {% question in latest_question_list %} <li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a></li> {% endfor %} </ul> {% else %} <p>no polls available.</p> {% endif %}
