Django/React set-cookie: csrftoken and X-CSRF-Token do not match and persists
I've been working through the nightmare that is decoupled React/Django and can't seem to figure out why my CSRF tokens, 1) do not match in the response, and 2) why the cookie is persisting between refreshes. Django View: def get_csrf_token(request): response = JsonResponse({'detail': 'CSRF cookie set'}) response['X-CSRFToken'] = get_token(request) return response Django CSRF Settings: CSRF_COOKIE_SAMESITE = 'Strict' CSRF_COOKIE_HTTPONLY = True CSRF_COOKIE_AGE = None React CSRF API Call: getCSRF = () => { fetch("/api/csrf/", { credentials: "same-origin", headers: { "Cache-Control": "no-cache, no-store, max-age=0, must-revalidate" } }) .then((res) => { let reqCsrfToken = res.headers.get("X-CSRFToken"); this.setState({csrf: reqCsrfToken}); }) .catch((err) => { console.log(err); }); } Now, the problem is that every time I ping the view with this call, the response headers between the set-cookie and the x-csrftoken will be totally different. Additionally, the original cookie value will persist across new calls and refreshes. set-cookie: csrftoken=KceWlQsdiQuM....... vs the X-CSRFToken Value x-csrftoken: Ymx3NCe5dwh....... I've checked and printed and logged everywhere, and the cookie value is always different. -

django including URLconf missing argument: 'view'

Django request.user is still authenticated after logging out
I have a reactjs app with Django as backend. There's a page that has a toggle which makes an API call to the backend updateIsPaid: id => instance({ 'method': 'POST', 'url': BACKEND_RECEIPTS_LIST_URL + id + '/', 'data': id }), and in the backend class ReceiptDetailView(APIView): permission_classes = (permissions.,) def post(self, request, *args, **kwargs): receipt_id = kwargs['id'] receipt = Receipt.objects.get(id=receipt_id) receipt.is_paid = not receipt.is_paid receipt.save() return Response(receipt_id, status=status.HTTP_200_OK) What I've noticed is that when I log out the user in frontend, which destroys the auth token and username stored in localstorage as well as calling django logout in the backend, when i hit the back button and jump back to the page with the toggle, I can still make the POST call and the result is still 200. What I was expecting is the POST call would return a 401. Further investigation shows that the user, while being logged out, the user still passes the IsAuthenticated perm check. This really confuses me and I don't know how to block the accessibility of such user upon logout. Any idea? -

(DRF) Why make a query before create when unique=True?
I have User model and serializer class which represents it. class User(models.Model): username = models.CharField(unique=True, max_length=50) is_admin = models.BooleanField(default=False) class CreateUserSerializer(serializers.ModelSerializer): class Meta: model = User fields = (“username”, “is_admin”) def create(self, validated_data: Dict[str, Any]) -> User: username = validated_data["username"] try: user_object = User.objects.create(username=username) except IntegrityError: raise UserAlreadyRegistered() return user_object My database holds lots of users(appr. 10 million). When I create another user, Django Rest Framework look at the model fields and check that if there are any unique=True fields. If there are, then it assigns “UniqueValidator”. This validator calls “filter_queryset” which means it query the database and check that are there any given username record. If there are not, then it creates the user. My question is, why DRF make a query before create operation? Since database(PostgreSQL) holds the field attributes, it knows that username field is unique, and it can throw an exception if I try to create user with the same username field. The reason I’m asking it, my application gets a lot of create operation, and each create operation I have to query my database, which is I think more costly than create it wihout making a filter query. Do I missing something in this operation? … -
Page not found when trying to use Django url routing
So I've been trying to use django dynamic url routing but when I try to open the link, Django shows me that the page was not found (error 404).

My generic Django ListView only updates once the user has logged out. How can I get it to auto-update?
I have a model called Strategy class Strategy(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) organisation = models.CharField(max_length=20, default="Enter Text Here") strategy_name = models.CharField(max_length=20, default="Enter Text Here") summary = models.TextField(blank=True) created_date = models.DateTimeField(default=timezone.now) class Meta: ordering = ["-created_date"] verbose_name_plural = "strategies" @property def name(self): return "%s - %s" % (self.organisation, self.strategy_name) def __str__(self): return self.name def get_absolute_url(self): # new return reverse('strategy_detail', args=[str(self.id)]) There are two views associated with the model. A ListView: class StrategyListView(ListView): model = Strategy context_object_name = 'strategy_list' template_name = 'simulator/strategy_list.html' And a FormView: class StrategyDefineView(FormView): template_name = 'simulator/strategy_define.html' form_class = StrategyForm success_url = '/simulator/' def get_initial(self): initial = super().get_initial() initial['user'] = self.request.user return initial def form_valid(self, form): form.save() return super().form_valid(form) When the user submits a form from the FormView, they are returned to the ListView. My problem is the ListView doesn't update until the user logs out and logs back in. So, if I submit a form on the FormView, I'm returned to the ListView where I don't see my submission. However, if I'm logged in as superuser, the ListView will update without the user logging out if I go to admin and then return to the ListView page. Does anyone know how I can … -
Removing Null nested fields in Django Serializer --- or how to iterate with Null?
This issue I am having is likely a React iteration problem but I think taking care of it at the root inside Django will be more efficient instead of on the front end. Possible remedies: ternary operation to conditionally display objects and parameters if not null remove null fields from response to avoid needing to do ternary operation through django itself Although, in the first place, I cannot seem to be able to iterate through my response. I have a double nested serializer: Models: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) class VideoProduct(models.Model): ... class ImageProduct(models.Model): ... class ProfileProduct(models.Model): profile = models.ForeignKey(Profile, on_delete=models.CASCADE) video_product = models.ForeignKey(VideoProduct, on_delete=models.CASCADE, blank=True) image_product = models.ForeignKey(VideoProduct, on_delete=models.CASCADE, blank=True) class Meta: unique_together = ('profile', 'video_product') unique_together = ('profile', 'image_product') Views.py: class VideoProductViewSet(viewsets.ModelViewSet): queryset = VideoProduct.objects.all() serializer_class = VideoProductSerializer class ImageProductViewSet(viewsets.ModelViewSet): queryset = ImageProduct.objects.all() serializer_class = VideoProductSerializer class ProfileProductsViewSet(viewsets.ModelViewSet): queryset = ProfileProduct.objects.all() serializer_class = ProfileProductsSerializer class ProfileBySlug(generics.ListAPIView): serializer_class = ProfileBySlugSerializer def get_queryset(self): slug = self.request.query_params.get('slug', None) queryset = Profile.objects.filter(slug=slug) if slug is not None: queryset = queryset.filter(slug=slug) return queryset Serializers: class VideoProductSerializer(serializers.ModelSerializer): class Meta: model = VideoProduct fields = ['id', 'price'] class ImageProductSerializer(serializers.ModelSerializer): class Meta: model = ImageProduct fields = ['id', 'price'] class ProfileProductsSerializer(serializers.ModelSerializer): video_product = VideoProductSerializer(read_only=True) image_product … -

TypeError at /order 'datetime.time' object is not callable Django
I want to make estimate making order time in my Django Apps but I am confuse about the time that cannot be calculated. I defined the datetime first then values, so I reduce the datetime - values, which I hope the result is now time reduced by datetime. here is my templatetags\cart.py : @register.filter(name="estimasipending") def estimasipending(datetime): values = (datetime.datetime.today) return datetime - values` here is my Views order.py : from django.shortcuts import render, redirect from django.views import View from store.models import Customer from store.models import Order class OrderView(View): def get(self,request): customer_id = request.session.get('customer') orders = Order.objects.filter(customer=customer_id).order_by("-date").order_by("-id") print(orders) return render(request,'order.html',{"orders":orders})` here is my HTML template {% for order in orders %} <tr> <td>{{ forloop.counter }}</td> <td><img height="80px" width="100px" src="{{ order.product.image.url }}" alt=""></td> <td>{{ order.product }}</td> <td>{{ order.price|currency }}</td> <td>{{ order.quantity }}</td> <th>{{ order.quantity|multipy:order.price|currency }}</th> <th>{{ order.date }}</th> <th>{{ order.datetime }}</th> {% if order.completed %} <th><span class="badge badge-success">Your Order is Ready</span></th> {% elif order.confirmed %} <th><span class="badge badge-success">We are making your order estimate {{ order.datetime|estimasipending }}</span></th> {% else %} <th><span class="badge badge-warning">Pending</span></th> {% endif %} </tr> {% endfor %}` and the error show like this : TypeError at /order 'datetime.time' object is not callable sorry for my bad english, I still learn.
