How can i order my votes by vote count? Django

Question

so i made it that my books will show in my admin but i dont know how to order the books(in the admin) by votes and not by last voted. I found some answers here on overflow but i wasnt able to integrate them by myself. Here are my files:

admin.py

from django.contrib import admin

from .models import Vote

admin.site.register(Vote)

apps.py

from django.apps import AppConfig

class SurveyConfig(AppConfig):

    name = 'survey'

forms.py

from django import forms

from .models import Vote

class VotingForm(forms.Form):

    chosen_books_options = forms.MultipleChoiceField(choices=[], label='Book Name', required=False,

                                                     widget=forms.SelectMultiple(

                                                        attrs={

                                                             'class': 'form-control'
                                                         }
                                                     ))
    other_book_name = forms.CharField(label='Other', max_length=100, required=False,
                                      widget=forms.TextInput(
                                        attrs={
                                              'class': 'form-control',
                                              'placeholder': 'Did we miss something?'
                                          }
                                      ))
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        unique_books_names = Vote.objects.order_by('book_name').values_list('book_name', flat=True).distinct()
        self.fields['chosen_books_options'].choices = [(book_name, book_name) for book_name in unique_books_names]

models.py

from django.db import models, transaction

class Vote(models.Model):

    book_name = models.CharField(max_length=200)

    count = models.IntegerField(default=0)
    def __str__(self):

        return '%s: %d votes' % (self.book_name, self.count)

    @classmethod

    def bulk_vote(cls, book_names):
        with transaction.atomic():
            for book_name in book_names:
                if len(book_name) == 0:
                    continue
                if Vote.objects.filter(book_name=book_name).exists():

                    Vote.objects.filter(book_name=book_name).update(count=models.F('count') + 1)
                else:
                    Vote.objects.create(book_name=book_name, count=1)

views.py

from django.shortcuts import render

from .forms import VotingForm

from .models import Vote

def index(request):
    if request.method == 'POST':
        form = VotingForm(request.POST)
        if form.is_valid():
            chosen_books_options = form.cleaned_data.get('chosen_books_options', [])
            other_book_name = form.cleaned_data.get('other_book_name', '')
            Vote.bulk_vote(chosen_books_options + [other_book_name])
        message = 'Thank You For Your Contribution!'
    elif request.method == 'GET':
        message = ''
    form = VotingForm()
    return render(request, 'templates/survey.html', {'form': form, 'message': message})

Within your admin, you can use the ordering attribute like so...

from django.contrib import admin

from .models import Vote

class VoteAdmin(admin.ModelAdmin):
    ordering = ('count',)

admin.site.register(Vote, VoteAdmin)
