the problem with my formset is that it does not take into account the amount of the modified article in the for loop, and i would also like to know how can i get the total sales perform. thank you

views.py :

def post(self, request):

        vente_formset = self.VenteFormSet(self.request.POST)

        if vente_formset.is_valid():

                for temp in vente_formset:

                    vente = temp.save()

                    article = vente.id_article

                    print('article de départ', article.quantite)

                    entre = article.quantite

                    entre -= vente.quantite_v

                    if entre >= 0:

                        article.quantite -= vente.quantite_v

                        article.save()

                        print('article final', article.quantite)

                    else:

                        vente.delete()

                        messages.warning(request, 'Stock insuffisant pour cette opération!')

        else:

            messages.warning(request, 'Formulaire invalide!')

        return render(request, self.template_name, {'form': self.VenteFormSet()})

in terminal pycharm :
-->article debut 15
.article fin 10
-->article debut 15
.article fin 8

what I wish to have :
-->article debut 15
.article fin 10
-->article debut 10
.article fin 3
