i error

got attributeerror when attempting value field user on serializer visitorserializer. serializer field might named incorrectly , not match attribute or key on queryset instance. original exception text was: 'queryset' object has no attribute 'user'.

the issue passing queryset serializer without setting many flag. error telling serializer trying access queryset.user when should accessing visitor.user, need tell serializer there multiple objects (instead of single one) passing many=true.
