I was following the django documentation and making a simple poll app. I have come across the following error :

This link http://127.0.0.1:8000/polls/ shows a blank page with 3 bullets. (I have 3 questions in my database and their id's are 5,6,7 because I have been deleting and adding the questions.)
My admin works fine!
I'm new to Django and have been searching and asking around and have been stuck on it for a while now.
You get the 404 on
http://127.0.0.1:8000/because you have not created any URL patterns for that url. You have included the urlhttp://127.0.0.1:8000/polls/, because you have included the polls urls withThe empty bullets suggest that there is a problem with your
polls/index.htmltemplate. It looks like you have a typo and have put{{ question.question_test }}instead of{{ question.question_text }}. Make sure that it exactly matches the template from the tutorial 3:
