Hide algorithm, iterations, salt in django password field
In django user table password are encrypted automatically with a secure algorithm (pbkdf2_sha256) with salt and iterations. But what I don't understand is why the django password field shows the algorithm, iterations and salt in this format: <algorithm>$<iterations>$<salt>$<hash> I thought those information are secret and I want to show only the hash. -

Request data empty with formData - Django Rest Framework
I am trying to save strings, floats and an image via a POST request made to a Django Rest Framework backend: # My view: class CreatePost(APIView): # tried with and without parser: # parser_classes = [FormParser, MultiPartParser] def post(self, request): serializer = PostSerializer(data=request.data) if serializer.is_valid(raise_exception=True): serializer.save(user_id=request.user.pk) return Response(serializer.data, status=201) return Response(serializer.errors, status=400) # My serializer: class PostSerializer(serializers.ModelSerializer): class Meta: model = Post fields = ("x", "y") And my JS frontend: const postBody = new FormData(); postBody.append('x', 'someValue'); postBody.append('y', 'someValue'); fetch('/api/v1/post', { method: 'post', body: postBody, credentials: 'same-origin', headers: { 'X-CSRFToken': getCookie('csrftoken'), 'Content-Type': 'multipart/form-data' } } However, sending as 'Content-Type': 'multipart/form-data' does not show any values in request.data in my backend. Sending as application/json works, but does not when one of the fields is an image. How can I process both text and image using form-data? I tried using parsers (FormParser and MultiPartParser) without success. -
Django, all views require login except `@login_not_required` decoratored views
Django is centered towards allow access to all the majority of the time, and restricting acces on the exception. I am making a site whereby I would like access restricted the most of the time, and the rare case is open to all. Ensuring that one has added a @login_required decorate to all views is error prone. I acheived this by creating a custom middleware like this. To keep track of open URLs, I defined a list, and then whenever I wished to open up a URL, I added it to the list, and the middleware checked the request path against this list, and allowed exceptions accordingly. This method above works, but I often mess it up with changing urls, and other issues to do with code reuse on different sites. Ideally I would like to create my own @login_not_requied decorator. How to get the class based view or function the request is going to call within the middleware, so I can check whether the view does not require login? -
Using Django's GenericForeignKey with Async Graphene Subscription
I've implemented graphql_ws to subscribe to updates from a Notification model that uses multiple GenericForeignKeys. My setup works well, except when I try to query information from those foreign objects. I then get the following error: graphql.error.located_error.GraphQLLocatedError: You cannot call this from an async context - use a thread or sync_to_async. From what I seem to understand, that's because some database query operations are being done outside the async context of get_notifications (that is, in the resolve_actor function). But I'm really not clear on how I can pull the operations of resolve_actor into the async context. I've unsuccessfully tried using prefetch_related (plus I'm not sure it'll work with multiple content types per Django's docs). Here's the code models.py class Notification(TimeStampedModel): # ... actor_content_type = models.ForeignKey(ContentType, related_name='notify_actor', on_delete=models.CASCADE) actor_object_id = models.CharField(max_length=255) actor = GenericForeignKey('actor_content_type', 'actor_object_id') # ... schema.py class ActorTypeUnion(graphene.Union): """ All possible types for Actors (The object that performed the activity.) """ class Meta: types = (UserType,) # here's there's only one type, but other fields have multiple class NotificationType(DjangoObjectType): actor = graphene.Field(ActorTypeUnion) def resolve_actor(self, args): if self.actor is not None: model_name = self.actor._meta.model_name app_label = self.actor._meta.app_label model = ContentType.objects.get(app_label=app_label, model=model_name) return model.get_object_for_this_type(pk=self.actor_object_id) return None # ... class Meta: model … -
"Incorrect type. Expected pk value, received User."
I have this two models: order and route. Route has a oneToMany relation with Order as you can see: class Order(models.Model): customer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='customer') retailer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='retailer') date_publish = models.DateField(default=datetime.date.today) date_available = models.DateField() weight = models.DecimalField(decimal_places=2, max_digits=5) description = models.CharField(max_length=500, null=True) route = models.ForeignKey(Route, related_name='orders', null=True, on_delete=models.CASCADE) class Route(models.Model): day = models.DateField() warehouse = models.ForeignKey(Warehouse, on_delete=models.CASCADE) start_time = models.TimeField() When a route is created I want to associate orders with that route, so I've done the following serializer: class routeSerializer(serializers.ModelSerializer): orders = OrderSerializer(many=True) class Meta: model = Route fields = ['day', 'warehouse', 'start_time', 'orders'] def create(self, validated_data): orders_data = validated_data.pop('orders') route = Route.objects.create(**validated_data) for order_data in orders_data: order_serializer = OrderSerializer(data=order_data) order_serializer.is_valid(raise_exception=True) orders = order_serializer.save() orders.route = route orders.save() return route I am sending a request like this: { "day" : "2021-12-12", "warehouse": "1", "start_time": "7:00", "orders": [ { "id": 15, "customer": 1, "retailer": 2, "date_available": "2020-12-12", "weight": "1.20", "description": null, "ordertimelocation": [ { "longitude": "12.1223000000000000", "latitude": "12.1223000000000000", "time_interval": [ { "start": "2021-07-21T10:10:00Z", "end": "2021-07-21T10:10:00Z" } ] } ] } ] } But the server returns a bad request: { "customer": [ "Incorrect type.

Django Ajax Post - works sometimes
I have a Django application where I am using AJAX to do a post when submitting a form. My issue is what do I set the URL to in my JavaScript? JavaScript snippet: $.ajax({ url: "search/do_post/", // the endpoint type: "POST", // http method data : { relevancy: relevancy, report_id: report_id, query: query_text, //csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val() }, urls.py snippet: path("search/do_post/", do_post_view, name="do_post"), My issue is that sometimes the above works and sometimes it does not. When it doesn't I get: POST http://localhost:1227/search/search/do_post/ 404 (Not Found) When I see that I then remove the search part from the url in my JavaScript. Sometimes that works and sometimes not. Any suggestions? -

How can I display the image to the desired product category? (if there are two separate models (Product and Image))
I can't figure out how to connect two models (product and images) in views and output images in html. At the moment, several images are loaded for a specific project (for example, photos of a 3D model) all this through the admin panel. There are several projects, that is, 3D models, engineering and so on. And now I can't display 1 of those uploaded images on my site for each product (project). That is, either all the images that were uploaded are displayed (both 3d models and books and engineering). Or if you use model.objects.first () displays the very first uploaded image( that is, the same for all projects).

Django Rest Framework: Register pure function-based views with router so it appears under API root
This is my views.py: class ChoicesViewSet(viewsets.ModelViewSet): queryset = SingleChoice.objects.all() serializer_class = SingleChoiceSerializer ... class AssessmentTakersViewSet(viewsets.ModelViewSet): queryset = AssessmentTaker.objects.all() serializer_class = AssessmentTakersSerializer ... @api_view(['POST']) @parser_classes((JSONParser,)) def studio_create_view(request, format=None): """" A view that accept POST request with JSON content and in turn build out the questions and choices. Post with application/json type. """ ... This is my urls.py: urlpatterns = [ # http://localhost:8000/survey/api/studio-create path('api/studio-create', views.studio_create_view, name='studio-create-api'), ] # drf config router = routers.DefaultRouter() router.register('api/choices', views.ChoicesViewSet) router.register('api/assessment-takers', views.AssessmentTakersViewSet) urlpatterns += router.urls This works functionally, and is considered feature-complete, but but because studio-create_view is not registered with the router, the path doesn't show up under the API Root which isn't great documentation wise. In other words, the API root from Django Rest Framework isn't aware of the path, and a GET request to the root would list only: http://localhost:8000/survey/ HTTP 200 OK Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept { "api/choices": "http://localhost:8000/survey/api/choices/", "api/assessment-takers": "http://localhost:8000/survey/api/assessment-takers/", ... } My question is, outside of viewsets that inherit from ModelViewSet, how do we get the custom views like studio_create_view to be registered with the router that Django Rest Framework provide so it's listed under the API root? One would be inclined to try something like: router.register('api/studio-create', views.studio_create_view, …
