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
<voyageDescription>
^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!
