Hi Hilaire, 

the thing is mongo is JSON based and in JSON dictionaries are key-string, 
value-anything so we cannot persist them “as is”. 
To do that I use a trick which is convert them to collections before 
persisting, using a helper class that comes with Voyage-Mongo, VOMongoKeyPair. 

For example, you could describe your dictionary attribute as this: 

mongoValue 


^VOToManyDescription new
attributeName: 'value';
convertNullTo: [ Dictionary new ];
accessor: (MAPluggableAccessor 
read: [ :anObject | 
anObject value associations 
collect: [ :each | VOMongoKeyPair 
fromAssociation: each ] ]
write: [ :anObject :value | (value collect: 
#asAssociation) asDictionary ]);
yourself

hope this helps, 

cheers!
Esteban

[Pharo-users] Voyage and Association

[Hilaire]

Hi,

I am having trouble to persist in a Voyage repository Association formed
with a key being a non string object (let's say a Month) and value a non
basic object, instance of a model object.

So far, I have an error bsonTypeCode not understood on my value object.
I could implement bsonTypeCode, but I suspect I will have trouble too
with the key, as I see from Voyage code it is persisted as a String.

An idea how to overcome this (without modifying my model)?

Fuel was persisting it fine.

Thanks

Hilaire
