Hello Stephen,
Thanks for your help, ok I think it's better to used views for what I need
to do.
Last question, how I can define this in view and template ?
For the moment I used 'for' & 'endfor' in my template to show all my items,
but I want to show "date2016" in only one field.
*Views.py*
from .models import Test
from datetime import datetime
from django.shortcuts import render, get_object_or_404
def test(request):
test = Test.objects.order_by('name')
*date2016 = Test.objects.filter(dateregister__contains='2016').count()*
??????
return render(request, 'test/test.html', {'test': test})
*Template:*
*{% for test in test %}<td>{{ test.name }}</td><td>{{ test.dateregister
}}</td>{% endfor %}{% test.date2016 %} ????Thanks for your help !*
