Django Generics custom quering

Question 1

I was working on notion like app, so I have a Note(consider as a Page in notion) and in that i am having blocks, where block having different id's and held with Note in Foreign field so now in views how can i use Generics to call all those blocks under a particular note. How should i modify get_queryset()

class BlockCreate(generics.ListCreateAPIView):    serializer_class = BlockSerializer    permission_classes = [IsAuthenticated]    def perform_create(self, serializer):        #save serializer in db        if serializer.is_valid():            serializer.save()        else:            print(serializer.errors)class NoteCreate(generics.ListCreateAPIView):    serializer_class = NoteSerializer    permission_classes = [IsAuthenticated]    def perform_create(self, serializer):        if serializer.is_valid():            serializer.save()        else:            print(serializer.errors)    def get_queryset(self):        ...?

My Serializers (correct me if anything wrong)

class BlockSerializer(serializers.ModelSerializer):    class Meta:        model = Block        fields = ['id', 'text']class NoteSerializer(serializers.ModelSerializer):    blocks = BlockSerializer(many=True, read_only=True)    class Meta:        model = Notes        fields = ['id', 'header', 'user', 'blocks', 'created_at']        read_only_fields = ['created_at']    def get_blocks(self, obj):        note_blocks = obj.noteblock_set.all().order_by('order')

How should i override get_queryset() to get only blocks related to that parent note

Question 2

Please include your Notes and Blocks model.

Question 3

I think a good way to handle this would be in yourserializers using serializer relations. Assuming in yourBlock model, you have a fieldnote which has aForeignKey relationship to theNotes model with itsrelated_name argument set toblocks, you can have a serializer like this:

class NoteSerializer(serializers.ModelSerializer):    blocks = serializers.PrimaryKeyRelatedField(many=True, read_only=True)      class Meta:              model = Notes              fields = ['id', 'header', 'user', 'blocks', 'created_at']          ...

If your related model has a__str__ method, you can useStringRelatedField instead ofPrimaryKeyRelatedField to display it:

See theserializer relations.
