Create questions by fetching from OpenTDB API
I am trying to create a tournament style game and am currently able to create tournaments but no questions. I have started to use forms and really like using them but hit a massive roadblock. I am wondering if I am trying to use multiple models within one view. When I save the tournament which is working, I want to get the difficulty and category from the form and use the OpenTDB API to generate 10 questions and save them. Here is the link to the API. Here are example questions if I chose General Knowledge and Easy... https://opentdb.com/api.php?amount=10&category=9&difficulty=easy. Please help, I have been stuck for days Models.py class Tournament(models.Model): DIFFICULTIES = (('E', ' Easy'), ('M', 'Medium'), ('H', ' Hard')) CATEGORIES = (('9', 'General Knowledge'), ('10', 'Entertainment: Books')) owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='tournaments') name = models.CharField(max_length=255) category = models.CharField(max_length=255, choices=CATEGORIES) difficulty = models.CharField(max_length=255, choices=DIFFICULTIES) start_date = models.DateField(blank=False) end_date = models.DateField(blank=False) class TournamentQuestion(models.Model): tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE, related_name='tournament_questions') text = models.CharField('Tournament question', max_length=255) View.py class TournamentCreateView(CreateView): model = Tournament form_class = AdminTournamentForm template_name = 'users/admins/admin_add_tournament_form.html' success_url = reverse_lazy('admins:admin_dashboard') def get_object(self): return self.request.user.admin def form_valid(self, form): tournament = form.save(commit=False) tournament.owner = self.request.user tournament.save() # THIS IS WHERE I AM REALLY CONFUSED difficulty … -
Django not reading any url pattern other than admin url

Django queryset order_by absolute value
I have a queryset that has a description attribute and a balance attribute. Currently, when I produce the queryset it is ordered from smallest to largest - - Model.objects.order_by('balance') #output Thing1 -120000 Thing2 -300 Thing3 7000 Thing4 100000 What I would like to order by is decending absolute value such that the result is: #Desired Output Thing1 -120000 Thing4 100000 Thing3 7000 Thing2 -300 I've tried passing various methods inside the order_by() but I think it needs to be an SQL type argument - which I can't figure out. I found this which uses a func expression when annotating. I couldn't get it to work with the order_by and the docs didn't help much. Is there a way to order a queryset in such a way? -

How should dektop app auth with a server be handled?
I have a simple django website that logged in users can upload files. I am now trying to make a PyQt5 app to make it possible to upload the files from the desktop, after authentication. For now, I'm using requests to https POST with username/password inserted in a login dialog to authenticate the user. If it is successfully, the program saves the session and uses it to send files. The username/password is then saved in a txt file to try to authenticate the user every time he runs the program (this is probably very insecure, but I didn't think of anything better). This system I implemented works well, but as I'm a begginner I would like to know if there is a better, more standard way of doing this. Thanks in advance. -
