How do I get FormSet to validate in my view?
I am doing something a bit unusual with FormSets. I am attempting to use a queryset as the input to my formset. This seems to be working at this point just fine. What isn't working is the form validation. Thanks in advance for any thoughts. I can't create this relationship via a traditional foreign key for reasons I won't bother people with. My Models.py class Team(models.Model): team_name = models.CharField(max_length=264,null=False,blank=False) class Player(models.Model): player_name = models.CharField(max_length=264,null=False,blank=False) team_pk = models.integerfield(Team,null=True,on_delete=models.CASCADE) My views.py class CreateTeamView(LoginRequiredMixin,UpdateView): model = Team form_class = CreateTeamForm template_name = 'create_team.html' def get_context_data(self, **kwargs): context = super(CreateTeamView, self).get_context_data(**kwargs) dropdown = self.request.GET.get("dropdown", None) queryset = Player.objects.filter(company_pk=dropdown) player_form = PlayerFormSet(queryset=queryset,dropdown=dropdown) context['player_form'] = player_form context['dropdown'] = dropdown return context def get_form_kwargs(self): kwargs = super(CreateTeamView,self).get_form_kwargs() kwargs['user'] = self.request.user kwargs['dropdown'] = self.request.GET.get("dropdown") return kwargs def get(self, request, *args, **kwargs): dropdown=self.request.GET.get("dropdown") self.object = self.get_object() context = self.get_context_data(object=self.object) self.object = None context = self.get_context_data(object=self.object) form_class = self.get_form_class() form = self.get_form(form_class) form_kwargs = self.get_form_kwargs() player_form = PlayerFormSet(dropdown=dropdown) return self.render_to_response( self.get_context_data(form=form, player_form=player_form, context=context, )) def form_valid(self, form, player_form): self.object = form.save() player_form.instance = self.object player_form.save() def form_invalid(self, form, player_form): return self.render_to_response( self.get_context_data(form=form, player_form=player_form, )) def post(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) dropdown=self.request.GET.get("dropdown") player_form … -
Can I use a 6-digit pin code instead of password in logging in my users in django authentication?
Is there a way where the users can login to my webapp using their username and a 6-digit pin (like the ones we use in our atms) instead of using the password? I am new to django and don't know how or where to look in this. Thank you! -

Sum annotated field with different cases that returns multiple rows of same objects
I have referral program in my project, and I want to calculate commission that should be paid to customers. Each order can have both referral attached and/or promocode attached. Only bigger discount applies to final price. Comission is also should be calculated according to bigger discount. On my Referral queryset I calculate it like so: if referral discount >= promocode discount: ((max discount - referral discount) * orders total price) / 100 else if referral discount < promocode discount ((max discount - promocode discount) * orders total price) / 100 With real field names is what I have now: qs = self.annotate( orders_total_old_price=Sum( 'orders__bookings__old_price', filter=orders_query, output_field=models.FloatField() ), # BEFORE DISCOUNT (used for commission calculation) commission_real=Case( When( # subtract bigger discount (promocode or referral) Q(orders__promocode__isnull=False) | Q(orders__promocode__sale__lt=F('discount') / 100), then=((F('user__broker_discount__value') - F('discount')) * F('orders_total_old_price')) / 100 ), default=( Cast( F('user__broker_discount__value') - (F('orders__promocode__sale') * 100), output_field=models.IntegerField() ) * F('orders_total_old_price')) / 100, output_field=models.FloatField(), filter=orders_query ), # <------ This annotation works fine, but in returned queryset I have multiple same objects commission=Case( When(commission_real__lt=0.0, then=0.0), default=F('commission_real'), output_field=models.FloatField(), filter=orders_query ), # only positive value or 0, shown in statistic registrations=Subquery( registrations.values('registrations'), output_field=models.IntegerField(), filter=orders_query ) ) It returns correct results, but I have multiple rows for same … -

Optimizing # of SQL queries for Django using "Prefetch_related" for nested children with variable level depth

How to send axios request to localhost?
I am currently trying to send an API request from a mobile app to a django server running on my computer. I am receiving a network error every time I try and send the request, regardless of the different headers I use (I am new to this so my headers could be totally wrong). Here is the request I am sending: export async function requestPrediction(img) { const url = 'http://127.0.0.1:8000/v1/predict/'; const data = new FormData(); data.append('file', { uri: img, type: 'image/jpeg', name: 'imageName' }); try { console.log(url, data); let resp = await Axios.post(url, data, { headers: { 'accept': 'application/json', 'Accept-Language': 'en-US,en;q=0.8', 'Content-Type': `multipart/form-data; boundary=${data._boundary}`, } }); console.log('######################\n','ACTION_RESULTS_SUCCESS',resp.data); } catch(error) { console.log('######################\n','ACTION_RESULTS_ERROR', error); } } I am pretty certain the URL I am sending to is the right address. When I type that URL in on my computer while the server is running I do not receive an error that the page wasn't found. Thanks for the help. I can post any server-side code that might be necessary. -
Test django application: need to delete a row in postgres, and then recover
I have a Django application which is interacting with postgres. To test application I want to delete several rows from a table and see the outcome of it on the retrieved data (queries are pretty complex, so to just see whether everything is good is hard otherwise). Whats the best practice to approach such a case? Most straightforward is to write down all of the data for the deleted rows, delete rows, test app, then reinsert the rows, but I feel like its too manual, time consuming and not how it should be done. Besides there is a small chance of missing something out and/or sometimes the model can't be easily deleted without deleting other model rows when they are related by a foreign key. -
Running Daphne with DotEnv in a systemd process
I'm using a .env file which contains the configuration for my Django app. I have a systemd service which runs Daphne (similar to what's below) [Unit] Description=WebSocket Daphne Service After=network.target [Service] Type=simple User=root WorkingDirectory=/home/django/myproject/src ExecStart=/home/django/myproject/venv/bin/python /home/django/myproject/venv/bin/daphne -e ssl:8001:privateKey=/etc/letsencrypt/live/myproject.com/privkey.pem:certKey=/etc/letsencrypt/live/myproject.com/fullchain.pem myproject.asgi:application Restart=on-failure [Install] WantedBy=multi-user.target Moreover, I'm using gunicorn through a similar mechanism, which works perfect. However, Daphne does not. When I run it through systemctl start daphne.service, it tells me that Django settings are improperly configured So, I tried setting the dotenv in the asgi.py file like so: dotenv.load_dotenv( os.path.join(os.path.dirname(__file__), '.env' )) os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings.dev') if os.getenv('DJANGO_SETTINGS_MODULE`): os.environ['DJANGO_SETTINGS_MODULE'] = os.getenv('DJANGO_SETTINGS_MODULE') But this just gives me the same error. Any ideas how to fix this? I checked out this response, but it seems ridiculous/redundant to set the environment variables in daphne.service. -

Python API to Generate Mask Number
I am working on a web app. This web app need a voice call features. When a client click on the Call Button then a call will be connect with the receiver. Call Here receiver is a registered user. But I need to keep private the contact number of the user. I have to ensure that from the web app i.e. site, when a client make call, client or caller will not be able to see the original phone number of the receiver i.e. I need to do Call Masking. For that reason I am looking for an API to generate a Mask Number. When a new user will sign up into the site then a mask number will be generate for that user using the original number of that user by the API. My Web app is python (django) based. So is there are any API available in Python for call Making. -
