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.
