Adding multiple random objects to ManyToManyField, based on user input
I am new to Django and attempt to create a geography game/quiz app. In a first step, the player chooses some game settings (number of rounds, difficulty, region/area). Based on the user's input, I want to assign countries to the user. In particular, I created these two classes in model.py. class Country(models.Model): name = models.CharField(max_length=90) code = models.CharField(max_length=15) subcontinent = models.CharField(max_length=25) subcontinent_code = models.CharField(max_length=15) continent = models.CharField(max_length=25) continent_code = models.CharField(max_length=15) def __str__(self): return self.name class Player(models.Model): name = models.CharField(max_length=90) number_rounds = models.IntegerField(default=10) difficulty = models.CharField(max_length=100, default='easy') area = models.CharField(max_length=100, default='world') countries = models.ManyToManyField(Country) def __str__(self): return self.name I created the corresponding forms.py for user input: class SetGameSettings(forms.ModelForm): class Meta: model = Player fields = ['name', 'number_rounds', 'difficulty', 'area'] labels = { 'name': 'Enter your username', 'number_rounds': 'Number of rounds', 'difficulty': 'Difficulty', 'area': 'Area', } widgets = { 'number_rounds': forms.NumberInput(attrs={'min': 1, 'max': 20}), 'difficulty': forms.Select(choices=[('easy', 'Easy'), ('medium', 'Medium'), ('hard', 'Hard')]), 'area': forms.Select(choices=[('World', 'World'), ('Africa', 'Africa'), ('Asia', 'Asia'), ('Europe', 'Europe'), ('Americas', 'Americas'), ('Oceania', 'Oceania')]), } And this is what views.py looks like: def home(request): if request.method == 'POST': form = SetGameSettings(request.POST) if form.is_valid(): form.save() #direct to next url form = SetGameSettings() return render(request, 'geo/home.html', {'form': form}) Until here, everything works fine.

Data saved in session in a view is not saved in pytest session. Why?
I am making a website with Django and would like to test the data stored in session with pytest. I have a very simple view : def dev_my_view(request): if request.method == "POST": post_data = json.loads(request.body.decode("utf-8")) product_id = post_data["productid"] request.session["basket"] = {"id": product_id} # print(request.session.items()) returns # dict_items([('foo', 'bar'), ('basket', {'id, '99'})]) # as expected response = JsonResponse({"id": f"product number {product_id}"}) return response Here is the test I have written : class TestViewsWithSession(TestCase): def test_my_view(self): session = self.client.session session["foo"] = "bar" session.save() url = reverse("home_page:my_view") response = self.client.post( url, json.dumps({"productid": "99"}), content_type="application/json", ) # print(session.items()) returns # dict_items([('foo', 'bar')]) # Test passes self.assertEqual(response.status_code, 200) # Test passes # response.content = b'{"id": "product number 99"} self.assertJSONEqual(response.content, {"id": "product number 99"}) # Test fails. KeyError: 'basket' self.assertEqual( session["basket"], {"id": "99"}, ) self.assertNotEqual( session["basket"], {"id": "Invalid value"}, ) When I add data to the session in the test (session["foo"] = "bar"), the session contains this data in the view. But, it looks it does not work the other way ... When some data is added to the session in the view (request.session["basket"] = {"id": product_id}), I cannot see this data in the test. Why ? -
404 for static images and media in Django in Production Mode
I am beginner in Django I am trying to run my application on Debug=False mode to simulate the production environment, I have added all the static url, and roots. My program is generating the static images in real-time from the video passed to the application during runtime.

Link to the application code: https://github.com/abhijitjadhav1998/Deepfake_detection_using_deep_learning/tree/master/Django%20Application Further to this application, I have added the STATIC_ROOT in the settings.py and added os.system('python manage.py collectstatic --noinput') in the views.py folder to populate the static path with images and videos before sending the response to the html page. But still I am getting the 404, I also checked the file with same name is avaliable in the location.

Django DRF filtering fields in serializer
I'm new to Django DRF and I'm trying to write a more organized code since the one below lacks the correct approach. I have 2 API endpoints: /api/order/info - which shows all the order fields /api/order/status - which shows only one field At the moment I have two serializers and two views as follows: serializers.py class OrderSerializer(serializers.ModelSerializer): class Meta: model = Order fields = ['order_id', 'data', 'status'] class OrderStatusSerializer(serializers.ModelSerializer): class Meta: model = Order fields = ['status'] views.py # /api/order/info - retrieves all fields class OrderInfo(generics.RetrieveAPIView): queryset = Order.objects.all() serializer_class = OrderSerializer def get_object(self): try: return Order.objects.get(pk=self.request.data['uuid']) except Order.DoesNotExist: raise Http404 # /api/order/status - retrives just one field, the status class OrderStatus(generics.RetrieveAPIView): queryset = Order.objects.all() serializer_class = OrderStatusSerializer # a serializer just for this def get_object(self): try: return Order.objects.get(pk=self.request.data['uuid']) except Order.DoesNotExist: raise Http404 The problem: the code works as expected, but it is pretty clear that it is duplicate! I'm creating a new serializer for just filtering one field, but I strongly believe that DRF makes this easier in some way. Could you please suggest a better approach? Thanks -

Regular expression to validate US phone numbers using Formik and Yup
I'm trying to validate us phone numbers inside my formik form using yep. I found some information on regex here on stackoverflow but it doesn't seem to be working. I basically need to be able to allow brackets, dashes and spaces aswell as the country code. The backend converts everything into something like this: (123) 123-1234 This is what i tried: validationSchema={Yup.object({ AdministratorCell: Yup.string() .matches(/([0-9]{3})[0-9]{3}-[0-9]{4}/, { message: "Invalid phone number", excludeEmptyString: false, }) })} I'm using https://github.com/google/libphonenumber in the backend for backend validation of those phone numbers which is why i need frontend validation to properly work or the form won't submit in some cases where users forget a number or format the number in a certain way. My issue is with what i tried so far is that i can only add the phone number with a certain formatting or it will not submit to the backend. -

Subscribe to google and outlook calendar through url causing problems
I'm working on a project using Django Rest Framework and icalendar. I've created an api which provides ics file for download. Users are provided with a url to the download api which they use to subscribe. However they are experiencing unexpected behaviour upon subscription. In case of google calendar it doesn't resync automatically at all. In one instance the calendar was subscribed successfully but there were no events being displayed on google calendar. Can anyone help confirm whether there is an issue with google calendar or am I missing something. for example not generating the file correctly views.py @action(detail=True, methods=['get'], permission_classes=[AllowAny], authentication_classes=[]) def download_file(self, request, *args, **kwargs): instance = self.get_object() ics_data = instance.ics_data file_name = "somefile" response = HttpResponse(ics_data.encode(), content_type='text/calendar') response['Content-Disposition'] = 'attachment; filename=%s.ics' % file_name return response sample url: https://api-mycompany.com/users/11184/calendar/download_file/ sample ics data: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//my company calendar// BEGIN:VEVENT SUMMARY:This Event DTSTART;VALUE=DATE-TIME:20220321T054500Z DTEND;VALUE=DATE-TIME:20220321T070000Z DTSTAMP;VALUE=DATE-TIME:20220419T085236Z UID:113874 DESCRIPTION:Some Event LOCATION:My Studio END:VEVENT END:VCALENDAR -
"django_admin_log" violates foreign key constraint
We have an application that uses custom login Middleware. We authenticate users from the token. The problem is that when this user wants to change any entry in admin panel, it gives an IntegrityError. insert or update on table "django_admin_log" violates foreign key constraint "django_admin_log_user_id_c564eba6_fk_auth_user_id" DETAIL: Key (user_id)=(567) is not present in table "auth_user". because this user is not in auth_user table, we set it to request.user only while authenticate with our external authentication system. how we can solve this issue?
