Is there a way to fix this issue? [closed]
I'm developing a website for an online store with Django and I want to show users a review of their cart while they are filling their billing addresses and stuff. I have my cart on another directory, so how do I bring that cart in my html form for checkout? I tried to do the same thing that I did with my cart.html but it is not working. Can anyone please help me out?

Django REST framework: how to combine the same type of model
How to combine many models in one query set so that it would be possible to use HyperlinkedModelSerializer using pagination? I need to connect many models with the same fields. That's what I did, but it doesn’t suit me.: **"models.py"** class Merketing(models.Model): question = models.CharField(max_length=500, unique=True) answer = models.CharField(max_length=500) class Management(models.Model): question = models.CharField(max_length=500, unique=True) answer = models.CharField(max_length=500) **"serializers.py"** class MerketingSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Merketing fields = ['id','question', 'answer'] class ManagementSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Management fields = ['id','question', 'answer'] class FiltersSerializers(serializers.Serializer): model_1 = MerketingSerializer(read_only=True,many=True) model_2 = ManagementSerializer(read_only=True,many=True) **"viesw.py"** class MerketingViewSet(viewsets.ModelViewSet): queryset = Merketing.objects.all().order_by('question') serializer_class = MerketingSerializer permission_classes = [permissions.IsAuthenticated] filter_backends = [filters.SearchFilter] search_fields = ['question'] class ManagementViewSet(viewsets.ModelViewSet): queryset = Management.objects.all().order_by('question') serializer_class = ManagementSerializer permission_classes = [permissions.IsAuthenticated] filter_backends = [filters.SearchFilter] search_fields = ['question'] class FiltersView(APIView): def get(self, request, *args, **kwargs): filters = {} filters['model_1'] = Merketing.objects.all().order_by('question') filters['model_2'] = Management.objects.all().order_by('question') serializer = FiltersSerializers(filters) return Response (serializer.data, status=HTTP_200_OK) -
django rest framework and redis
I'm working on a project where there are like 30 to 40 gps trackers, I want to give the client the ability to select any tracker and then track its location. I was able to get the trackers to communicate using a django rest framework, being a real time application I'm using channels. The database is divided such that the one table is for the trackers, and another table for tracking their current location. Using the seconds table I'm able to server the requested trackers location to the user. I wanted to know if there is a way for me to implement django rest framework with redis, such that the post request from the tracker is directly cached, instead of inserting or updating in the database. The historical location of the trackers is not important to me, just their current location. -

Share data from host to docker container
I have an application that writes correctly a file generated on a docker container to the host machine. Using the same approach, I was thinking that the problem would be similar if I want to read a file on the container but coming from the host. I use volumes in the docker-compose file: volumes: - /home/qcuci/dockerized_apps/unidosi_logs:/app/unidosi/data/unidosi_logs # here I want to read from the host - /home/qcuci/dockerized_apps/unidosi_silicon:/app/unidosi/data/unidosi_silicon # here I write to host Why I can't read the file? In fact, if I use the bash command I can see that the files aren't copied from the host to the container accordingly -
