    # This is a simplified version. You'll need to adapt it to your
    # existing upload_spectrum logic, especially file handling and metadata extraction.
    # Consider using a serializer for validation and saving.
    # For example, if your SpectrumSerializer can handle file uploads:
    # serializer = SpectrumSerializer(data=request.data, context={'request': request})
    # if serializer.is_valid():
    #     serializer.save(uploaded_by=request.user)
    #     return Response(serializer.data, status=status.HTTP_201_CREATED)
    # return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

    # Placeholder logic:
    if 'binary_data_file' not in request.FILES or 'material_name' not in request.data:
        return Response({'error': 'Missing required fields (binary_data_file, material_name).'},
                        status=status.HTTP_400_BAD_REQUEST)

    # Add your file processing and model creation logic here
    # Example:
    # spectrum = Spectrum.objects.create(
    #     material_name=request.data['material_name'],
    #     binary_data_file=request.FILES['binary_data_file'],
    #     uploaded_by=request.user
    # )
    # # Perform any additional processing like metadata extraction if needed
    # spectrum.save()
    # return Response({'message': 'Spectrum uploaded successfully', 'id': spectrum.id}, status=status.HTTP_201_CREATED)

    return Response({'message': 'API upload endpoint hit. Implement actual upload logic.'}, status=status.HTTP_200_OK)
