How can i update a page without reloading with Ajax and Django Rest Framework?
In my Django project, i'm trying to create a page where some data is uploaded in real time, without reloading the whole page. That data is retrieved from a database, so i created an API endpoint with Django Rest Framework, the problem is that i don't know how to go from here. I already know that, to update the page, i'll need to use Ajax. But i don't know how to create the Ajax part. I think that i need to add a POST request in my template, but that's all i know for now. Can someone give me some direction on where to go from here? Any advice is appreciated Basically the Ajax request should call the endpoint, which is http://127.0.0.1:8000/tst/, and update the data every X (something between 1 and 5 seconds). serializers.py class tstSerializer(serializers.ModelSerializer): class Meta: model = tst fields = ('ticker', 'Price', ) def create(self, validated_data): return tst.objects.create(**validated_data) views.py class tstList(generics.ListCreateAPIView): queryset = tst.objects.using('screener').all() serializer_class = tstSerializer class tstDetail(generics.RetrieveUpdateDestroyAPIView): queryset = tst.objects.using('screener').all() serializer_class = tstSerializer template.html <h3>Here will be a table with the data uploaded in real time..</h3> -

Django Rest Framework - Bad request
I'm trying to call an api endpoint on my Django project from my frontend. The endpoint is at the url /tst/. I need to retrieve data from that endpoint, in order to populate my page with that data.

Best approach to building a student marks tracking system
Am trying to build a system in django which will allow me to track marks of students from various semesters in various subjects.
