This is what you write in your views.py:
First, to count it, you have to import the model itself
If models.py and views.py both belong to same app:
from .models import Question
If they belong to different apps:
from <appname>.models import Question
I'll assume they belong to the same app, in views.py:
from django.shortcuts import render
from .models import Question
def index(request):
number_of_questions = Question.objects.count()
context = {
'number_of_questions':number_of_questions,
}
return render(request, '<appname>/index.hmtl>', context)
On the first line of the function it just counts the number of questions with .count() method which comes with django. On the second line we define context that we want to use in template, in this case 'number_of_questions':number_of_questions, so in the html template to display this number we'll use {{ number_of_question }}, have we defined it like so: 'questions':number_of_questions, then in the template we would use {{ questions }}, the end result will be that it shows number_of_questions.
In index.html (Or whatever you named the template):
<p>number of questions:</p>
<p>{{ number_of_questions }}
If you have trouble understanding anything I suggest you read through these:
Django documentation on templating
Some information about python dictionaries
EDIT:
I also highly recommend reading this:
