im learning Django framework and having some issues that i dont get it.
Actually i have apps like Polls/ Blog/ and my homepage/ installed and working as i want.

My problem is to display each data into my homepage_index.html like :
_ how many Question my polls contain
_ how many Article my blog contain

Both of informations are from different apps.

From Django Tutorial i found a solution to display by example my last 3 Question.objects like this.

homepage/views.py :

from django.views import generic
from django.utils import timezone
from polls.models import Question


class homepage(generic.ListView):
    template_name = 'homepage/homepage_index.html'
    context_object_name = 'latest_question_list'

    def get_queryset(self):
        return Question.objects.filter(pub_date__lte=timezone.now()).order_by('-pub_date')[:3]

my homepage_index.html working :

 {% if latest_question_list %}
     <ul>
        {% for question in latest_question_list %}
            <li><a style="color: white; text-decoration: none;" href="{% url 'polls:detail.html' question.id %}">{{ question.question_text }}</a></li>
        {% endfor %}
     </ul>
{% else %}
     <p>No polls are available.</p>
{% endif %}

How can i define in my homepage/views.py with multiple context_object_name and multiple queryset please ?
I tryied to read many documentations but im still failing

You can find more detail at the offical docs, what you need to do is same as the now value in the demo. https://docs.djangoproject.com/en/4.0/ref/class-based-views/generic-display/#listview

you need to override get_context_data

1. calculate the number of questions or blogs, or other datas, put them into context
2. and then render the number at homepage_index.html .

I found a solution without override the get_context_data but i solved half of my problem.( i fail to use the override get_context_data method). Right now i can display multiple informations i wanted in my homepage_index.html like this :

from blog.models import Article
from polls.models import Question

from django.shortcuts import render

def homepage(request):
    list_of_title_article = Article.objects.all()
    list_of_title_question = Question.objects.all()

    return render(request, 'homepage_index.html',  {'latest_question_list': list_of_title_question, 'latest_article_list': list_of_title_article})

It look working as i want but i still dont have any counter method of my objects.

Right now im trying to use Question.objects.all().count() and i have no context to deliver into the render(request, ...)
