[Pharo-project] MongoTalk update
Hi guys, Lately I worked a bit on the Pharo Mongo driver for SmalltalkHub. I made several changes (in the new version 1.4): The query API changed: - MongoCollection>>query: now takes a 1 arg block, improving the API quite a bit. Queries like: aCollection query: (aCollection query query: { 'foo' -> 'bar'} asDictionary; yourself) Is now written: aCollection query: [ :query | query where: { 'foo' -> 'bar'} ] Sending #asDictionary has also been made optional, the query builder will send #asMongoQuery to the query collection. The MongoQueries package: Version 1.4 comes with a new package MongoQueries, a small DSL allowing us to use traditional blocks instead of dictionaries to perform queries. This is optional and backward compatible. Queries like: aCollection select: { '$or' -> { 'name' -> 'foo'. 'age' -> { '$gt' -> 23 } asDictionary } asDictionary } asDictionary can be expressed: aCollection select: [ :each | (each name = 'foo') | (each age > 23) ] The MongoQueries package should support the entire mongo query language (including nested queries), and comes with unit tests.

Hey Nico, I looked into your new stuff and I like it. Especially the MongoQueries stuff is very simple and clean approach to do a small DSL. That boosts the usability of MongoTalk extremely. Bravo! Norbert Am 19.11.2012 um 15:37 schrieb Nicolas Petton <petton.nicolas@gmail.com>:

Nicolas will do a tutorial to us and we will produce some slides and after a chapter about mongoDB :) Stef On Nov 22, 2012, at 11:28 AM, Norbert Hartl wrote:

Thanks Norbert! It's cool to know that you like it :) Together with Esteban's work on Voyage, it allows us to do extremely cool stuff with Mongo and Pharo. What I like with Voyage-Mongo + MongoQueries is that objects are persisted without any effort, it just works, and we can query Mongo collections like we would do with Smalltalk collections.

Sure, that sounds cool. I didn't look into the new voyage, yet. But I need to tell Esteban how cool it is to clear a past misunderstanding :) Norbert

are you talking about serializing objects (or subgraphs) directly, and storing them in mongo db ?
