Answer 1

obj = Plate.objects.first() # this will return you object

in objects there are multiple attributes there you've to get only your file attribute like this

@api_view(['GET',])
def my_view(request):
    obj = Plate.objects.first()
    response = HttpResponse(obj.file, content_type=' 
    application/vnd.openxmlformats-officedocument.spreadsheetml.sheet,
  application/vnd.ms-excel')
    return response
