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: Am 17.04.2014 um 10:08 schrieb Olivier

Re: [Pharo-users] Voyage: how to delete references to objects.

Hi Norbert, for me the gain within smalltalk is huge because I want to navigate from person to trip and from trip to person by the attributes without asking mongo for the correspondent object via indexes. Don't you think that this is a question of design of the object model and should not be deci

Re: [Pharo-users] Voyage: how to delete references to objects.

Sabine, I read the case now the first time. Just one note. Having references in both directions is probably not the best idea if using a non-object store. For navigating the graph it might be good but for persisting it is not. The serialization is a lot more complex if you do and the gain is no

Re: [Pharo-users] Voyage: how to delete references to objects.

thanks Robert for the explications. I agree with you that's the best way to remove a book is to delete the reference in ComicsCollection. But how to do that ? Must I simply remove the reference in the ordered collection ? Voyage will syncronize automatically the data in memory with the content o

[Pharo-users] Voyage: how to delete references to objects.

Hi, I'm using Voyage in a Pharo application. I have two MongoDB collections which are ComicsCollection and ComicsBook. Each book is attached to a instance of ComicsCollection. The reference of each book is stored in an ordered collection (in the instance of ComicsCollection). The problem is th

I think this is simply a case of optimistic locking - there is a general way and very often db specific ways first you get the current active value ... (one row) currentValue from "select counterfield from tablename" then you update the table (single row) update tablename set counterfield
