Hi,

the solution to my initial issue is to create a class MyClass with two class side methods

MyClass class >> isVoyageRoot

^ true

MyClass class >> descriptionContainer

�� �� <voyageContainer>

�� �� ^ VOContainer new

�� �� �� �� collectionName: 'myCollection';

�� �� �� �� yourself

Also, to properly read the data one should add instance variables to depending on what is in the database. For example:

{ "_id" : ObjectId("5900a0175bc65a2b7973b48a"), "item" : "canvas", "qty" : 100, "tags" : [ "cotton" ] }

In this case MyClass should have instanceVariables: 'item qty tags' and accessors.

Plus, on the class side

mongoItem

<mongoDescription>

^ VOToOneDescription new

attributeName: 'item';

kind: String;

yourself

mongoQty

<mongoDescription>

^ VOToOneDescription new

attributeName: 'qty';

kind: Integer;

yourself

mongoTags

<mongoDescription>

^ VOToOneDescription new

attributeName: 'tags';

kind: OrderedCollection;

yourself

After that one can connect to database and get the information.

| repository |��

repository := VOMongoRepository database: 'databaseName'.

repository selectAll: MyClass

Big thanks to Sabine, Esteban and Holger!

Cheers,

Mark

Happy to help. I got this information from Udo Schneider in slack several weeks ago.

As far as I know, he works on an update for several things concerning mongo but I don't know when he will release it.

Khrystyna ,

I also use a new version of mongo with authentication (but only old version) and wired Tiger.

I am not sure but possibly you can try to overwrite the following method to fix the problem:

MongoDatabase>>collections

| reply names |��

reply := self command: {(#listCollections -> 1)} asDictionary.

names := ((reply at: 'cursor') at: 'firstBatch') collect: [ :each | each at: #name ].

^ names collect: [ :each | MongoCollection database: self name: each ]
