Views.py & queryset

Hello,

Sorry first project...

I can run :  Test.objects.filter(dateregister__contains='2016').count()    in manage.py shell, result is ok.
In template, {{ test.count }} works well, but I tried {{ test.filter(dateregister__contains='2016').count() }} without success.
I can't use queryset directly in the template ?  (need to modify views.py ?)

Models.py:
from __future__ import unicode_literals
from django.db import models
from django.utils import timezone

class Test(models.Model):
    name
= models.CharField(max_length=10, editable=False)
    dateregister
= models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True, editable=False)
   
def __str__(self):              # __unicode__ on Python 2
       
return self.name

Views.py:
from .models import Test
from datetime import datetime
from django.db.models import Q, F, count
from django.shortcuts import render, get_object_or_404

def test(request):
    test
= Test.objects.order_by('name')
   
return render(request, 'test/test.html', {'test': test})

Thanks for your help !!
