how to duplicate document with Voyage

Hi,

I'm using Voyage and I need to duplicate an existing document in a Mongo
database. I suppose that the id must be changed before saving.

What is the best way to do that ?

Best regards
Olivier ;-)

If you need a shallow copy then you better just copy the object and store it. Changing the id is asking for trouble I guess. That would probably work if you implement #= on those objects but I think it is a hack.

anObject copy save

should do.

Hi norbert

Olivier was doing a copy but it did not work and we thought that
Voyage should offer a clone or something like that that does not mess up
with the id.
Because we already corrupted nicely a mongoDB.

Hi,

copy should not mess with the id (unless your objects redefines = and hash).
I can take a look if Olivier is around tomorrow.

Thanks. I told him to talk to you but this is a really shy guy :)
He is pushing Pharo to build other application in the lab :)
