django-debug-toolbar configure INTERNAL_IPS for docker, compatible ip6
I just got django-debug-toolbar to work in Docker, but with a bit of a hack. The official instructions say if DEBUG: import socket # only if you haven't already imported this hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS = [ip[: ip.rfind(".")] + ".1" for ip in ips] + ["127.0.0.1", "10.0.2.2"] However I saw no toolbar. In my template html I printed {{request.META.REMOTE_ADDR}} and noticed that it was an IP6 address. So I changed the above INTERNAL_IPS logic to if DEBUG: hostname, _, ips = socket.gethostbyname_ex (socket.gethostname()) ips = [ip[:ip.rfind(".")] + ".1" for ip in ips] INTERNAL_IPS += ips INTERNAL_IPS += ['::ffff:'+ip for ip in ips] This works but it feels hacky. Is there a better way to do this? -
find alternative to celery-beat to run slow tasks
I have a problem with a celery task that I have to run every 30 seconds. The task consists of connecting through ModbusTCP to a system to read some values. The problem is that I have to read these values from several systems and in 30s it is not able to finish the execution of all of them. As at the moment I do it is through celery-beat I execute a task that consists of a loop that goes through all the systems to which I have to connect to read the data. The connection attempt sometimes takes a while and that is what causes that in 30 seconds I don't have time to execute the whole loop. Is there any alternative to celery-beat that can fit the functionality I am looking for? Thanks! Try to find a solution for the problem or any alternative to solve my situation -
Django REST Framework Viewset Executes Actions Multiple Times and Shows 'None' for GET Requests
I have a Django REST framework viewset with multiple actions such as list, create, and more.

Inbuilt password validator for password reset Django
In the page where the user reset the password (name="password_reset_confirm"), I want to use inbuild django password validator. But unfortunately, I am not able to bring them up on the page. Currently the two password fields are visible and when I change the password, it is working fine but I need to include the password validation that is offered by Django which will check for these below conditions. Your password can’t be too similar to your other personal information. Your password must contain at least 8 characters. Your password can’t be a commonly used password. Your password can’t be entirely numeric. urlpatterns = [ path('admin/', admin.site.urls), path('login/', views.loginPage, name = "user_login"), path('register/', views.registerPage, name="user_register"), path('registration-success/', views.registerSuccessPage, name="register_success"), path('logout/', views.logoutPage, name = "user_logout"), path('', views.home, name = "home"), path('',include('forum.urls')), path('', include('subscription.urls')), path('', include('core.urls')), #password reset path('reset_password/', auth_views.PasswordResetView.as_view(template_name = "password_reset.html"), name="reset_password"), path('reset_password_sent/',auth_views.PasswordResetDoneView.as_view(template_name = "password_reset_sent.html"),name="password_reset_done"), path('reset/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name = "password_reset_confirm.html"),name="password_reset_confirm"), path('reset_password_complete/', auth_views.PasswordResetCompleteView.as_view(template_name = "password_reset_done.html"),name="password_reset_complete"), ] -

Why custom clients might be ignored by unittest in Django?
Exploring Unittest, can't figure out why these tests ignore custom clients prepared in setUp() method and use the built-in self.client (== self.guest_client).

In Django, can you filter a queryset by a parent (uses ForeignKey field) model's field value?
Let's say you have models defined for Transaction, Category, and TransactionDetail, like so: class Transaction(models.Model): details = models.ForeignKey(TransactionDetails, verbose_name="Transaction Details", on_delete=models.PROTECT, default='',null=True) category = models.ForeignKey(Category, verbose_name="Transaction Category", on_delete=models.PROTECT, default='') class Category(models.Model): name = models.CharField(max_length=255, verbose_name="Category Name", default="") class TransactionDetails(models.Model): value = models.CharField(max_length=255, verbose_name="Transaction Detail", default="") In views.py I am trying to figure out how to filter TransactionDetails objects that are attached to a Transaction.details field AND have a specific Transaction.Category.name. In other words, I'd like to return a queryset of TransactionDetails that are related to Transaction objects with a category.name of "uncategorized". I understand how to use the objects manager filter for the other way around: uncatTransactions = Transaction.objects.filter(category__name="Uncategorized") But am unsure how this would be done for TransactionDetails: uncategorizedTrxDetails = TransactionDetails.objects.filter(referenceToParentUsingForeignKey__category__name="Uncategorized") -

Django form bringing unselected data
Am creating a django form that enables me enter student marks but it works best for the start and it then brings students I didn't select . The project that collects student marks but am trying to make a form that inputs marks after selecting the students on one form but this works well before I enter any marks but it then brings all the students whose marks I've already entered plus those I select for new entries. In my views.py I have that @login_required def create_result(request): students = Student.objects.all() if request.method == "POST": # after visiting the second page if "finish" in request.POST: form = CreateResults(request.POST) if form.is_valid(): subjects = form.cleaned_data["subjects"] session = form.cleaned_data["session"] term = form.cleaned_data["term"] students = request.POST["students"] results = [] for student in students.split(","): stu = Student.objects.get(pk=student) if stu.current_class: for subject in subjects: check = Result.objects.filter( session=session, term=term, current_class=stu.current_class, subject=subject, student=stu, ).first() if not check: results.append( Result( session=session, term=term, current_class=stu.current_class, subject=subject, student=stu, ) ) Result.objects.bulk_create(results) return redirect("Results:new-results") # after choosing students id_list = request.POST.getlist("students") if id_list: form = CreateResults( initial={ "session": request.current_session, "term": request.current_term, } ) studentlist = ",".join(id_list) return render( request, "Results/resultsentry1.html", {"students": studentlist, "form": form, "count": len(id_list)}, ) else: messages.warning(request, "You didnt select any … -
Django channels with react axios runs twice
I use django channels and react to create a chat app. I have two models. Message and chat. Message just contains each message users have send, and chat contains more information about the chat of 2 users. When a new message is created I display it on screen and then create a new model of message with axios. After that I also create a chat one. My problem is that sometimes 2 messages are created at one time even if only one is displayed on the screen. I have noticed that react doesn't re-render so I don't know what causes this. Also it is inconsistent, some times only one is made and when the other user writes a message they start doubling. useEffect(()=> { let ran = true; chatSocket.onmessage = function(e) { if (ran == true) { const data = JSON.parse(e.data); setMessages(old => [...old, <div id={data.sendby.username == currentUser[0]?.username ? 'ownUser' : 'elseUser'}><p ref={oneRef} data-username={data.sendby == currentUser[0]?.username ? 'ownUser' : 'elseUser'}>{data.message}</p></div>]) axios.post('http://127.0.0.1:8000/create_message/', { headers: { 'Content-type': 'application/json' }, message:data.message }).then(res=>{ const formData = new FormData() formData.append('chat_room',roomName) formData.append('sender',JSON.stringify(data.sendby)) console.log(formData.forEach(el => console.log(el))) axios.post('http://127.0.0.1:8000/create_chat/', formData, { headers: { 'Content-type': 'multipart/form-data' } }).then(res=>console.log(res)) }) } } return () => { ran = false; }; },[currentUser]) … -
Django - setting a model pk to None and saving returns "ValueError: Cannot force an update in save() with no primary key."
I have already figured this out but I could not find an answer to this and will post because somebody might find it helpful. Here is the code that was causing problems: models.py class SModelQuerySet(models.QuerySet): def stubbed_outputs(self): return self.defer("outputs").annotate( has_outputs=models.Case( models.When( models.Q(~models.Q(outputs={}) & models.Q(outputs__isnull=False)), then=True, ), default=False, output_field=models.BooleanField(), ) ) def for_user(self, user): return self.filter(user=user) class SModelManager(models.Manager): def get_queryset(self): return SModelsQuerySet(self.model, using=self._db).stubbed_outputs() def for_user(self, user): return self.get_queryset().for_user(user) class OutputsManager(models.Manager): def get_queryset(self): return super().get_queryset().only("outputs") def for_user(self, user): return self.get_queryset().filter(user=user) class SModel(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, db_index=True) name = models.CharField(max_length=50) description = models.CharField(max_length=500, null=True, blank=True) inputs = models.JSONField(default=dict) outputs = models.JSONField(default=dict) objects = SModelManager() outputs_objects = OutputsManager() class Meta: verbose_name_plural = "scientific models" db_table = "smodels" managed = False def __str__(self): return self.name views.py class SharedModelViewSet(viewsets.ModelViewSet): permission_classes = (IsAuthenticated,) serializer_class = serializers.SharedModelSerializer @action(detail=True, methods=["post"]) def save(self, request, pk=None): shared_model = self.get_object() model = get_object_or_404( models.SModel.objects.filter(user=shared_model.share_from), pk=shared_model.model_to_share_id, ) model.pk = None model.user_id = shared_model.share_to.id model.save() shared_model.delete() return Response( serializers.SModelSerializer(model).data, status=status.HTTP_200_OK ) When this view was trying to save, I was getting an error like this: "ValueError: Cannot force an update in save() with no primary key." I could not figure this out and it was working a few weeks ago. -
