Django Paginator doesnt work properly, how can i resolve

Question

the django paginator data I use in my project does not work properly in sorting, for example, although I have records dated 2021 in my records, when I sort by date, it only sorts records dated 2020, here is my codes:

images;

after sorting;

about 2021 dated records finding by filtering;

views.py;

gmembers_list = gunluk.objects.all()
paginator = Paginator(gmembers_list, 1000000000000000)
page = request.GET.get('page')

try:
    gmembers = paginator.page(page)
except PageNotAnInteger:
    gmembers = paginator.page(1)
except EmptyPage:
    gmembers = paginator.page(paginator.num_pages)
return render(request, 'gunlukistakibi.html', {'gmembers': gmembers})a

html for listing;

            <div class="card-header">
                <i class="fas fa-table"></i>

Answer 1

I don't see any sorting by date in your code. Can you try with gmembers_list = gunluk.objects.all().order_by("-date") (or whatever your date field on this model is named)?

By default, if you don't provide an ordering on the Model.Meta class, and no ordering when building your queryset, the sorting can be unstable depending on your database.

Answer 2

You did not add any logic to tell django how to retrive the data from db. You either add Meta class to your model class

class ModelName(models.Model):
    ....
    datetime = models.DateTimeField(default=datetime.now)
    class Meta:
        ordering = ['-datetime']      
    def __unicode__(self):
        return unicode(self.name)

or:

  gunluk.objects.all().order_by("-date")
