Re: [Pharo-users] Group and member with Voyage

      I think that the question could be rephrased as:

How to map a collection with elements of different classes?

Am I asking for too much?

More or less, I have this working.
In the Group class I have a description named:
descriptionMembers
<mongoDescription>
^VOMongoToManyDescription new
attributeName: 'members';
accessor: #members;
kind: Member;
beLazy;
yourself
And in the Member class I have
descriptionGroups
<mongoDescription>
^VOMongoToManyDescription new
      attributeName: 'groups';
      accessor: #groups;
      kind: Group;
      beLazy;
      yourself
But what if Member is an abstract class and the elements can be any of
SingleMember or ComplexMember?, each one is stored in a separate
collection in Mongo.
If I do specify #kind: Member in my #descriptionMembers it won't work.
Any ideas?

It seems that I mistook the question for something easy enough for me to answer! Unfortunately, I don't have any knowledge of Voyage+MongoDB so can't really give the proper answer.
Thanks anyway, it is a problem you'll never find in GemStone/S ;-)
