Found a solution. It works when add fields parameter to serialize, but
only when without parent field:
e.g. serializers.serialize("json", c, fields='name,rank') works
perfect, while
serializers.serialize("json", c, fields='name,rank,parent') raises
DoesNotExist exception
where c = Category.objects.filter(parent__exact=0)
