Django models sorting by address

Trying to fill a form returns Cannot query "useraccount": Must be "SellerAccount" instance
I am trying to build a trading market sort of app, and I have models that have foreign keys connected in a multiple level sort of hierarchy. They are as follows: models.py class SellerAccount(models.Model): # unimportant fields user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) def __str__(self): return self.user.username class SellerCardDetail(models.Model): # unimportant fields seller_details = models.ForeignKey(SellerAccount, on_delete=models.CASCADE) def __str__(self): return self.seller_details.user.username The forms in question are simply formsets with only the required fields added as an argument. views.py @login_required(login_url="/account/") def add_seller_card(request): card_form = SellerCardFormSet # imported from forms.py user = SellerAccount.objects.get(user=request.user) # imported from models.py if request.method == "POST": formset = card_form(request.POST, request.FILES, instance=user) if formset.is_valid(): formset.save() messages.success(request, "Successfully listed a card!") return redirect("/") else: formset = card_form(instance=request.user) return render(request, 'account/profile/addcard.html', {"add_card": formset}) else: print(type(user)) return render(request, 'account/profile/addcard.html') What I thought would happen is that I would get the SellerAccount instance with user = SellerAccount.objects.get(user=request.user) but that has proven to be untrue. I wanted to test what I would get when I let that query through with the simple print(type(user)), and it returns <class 'account.models.SellerAccount'>. I'm baffled by this, both because my understanding of Django is not good enough, and because this should work in theory and it doesn't. Since I can't get … -

how to send post request when browser closing in React

Running background tasks in Flask using Django
I have a web application built fully using Flask, at the moment the entire project runs on flask, i'm using many flask libraries for various functionality. However, some of these tasks i am running are very time consuming and take around 5 minutes to finish, and because of this if someone was to run this task and someone else wanted to navigate the website they would be stuck loading while the other lengthy task is done.

Please check Apple Connect.", "danger") return redirect(url_for('offercodes',appID=appID)) return render_template('newOfferCodeApple.html', … -
