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. Norbert

anObject copy save
+1
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. Stef On 17/4/14 10:17, Norbert Hartl wrote:

Hi, copy should not mess with the id (unless your objects redefines = and hash). I can take a look if Olivier is around tomorrow. Esteban On 17 Apr 2014, at 21:41, pharo4Stef@free.fr wrote:

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 :)
