Fwd: rogue 2.3.0

[Jason Liszka]

Some new features:

$setOnInsert

A set that only applies when an upsert is an insert. The query below will create an initialized record but avoid resetting the count if the record already exists. Example:

User.where(_._id eqs uid).modify(_.impressionCount setOnInsertTo 0).upsertOne()

More info: http://docs.mongodb.org/manual/reference/operator/update/setOnInsert/

'eqs' on List fields

Ability to test a list field for strict equality. Compare to $all.

User.where(_._id eqs uid).and(_.tags eqs List("LocalSales", "ThirdParty"))

$push/$each/$slice

Push items into a list while keeping the list a fixed size. For example, this rogue query:

User.where(_._id eqs uid).modify(_.lastImpressions push (iids, -5))

produces the following modify expression:

{ $push: { lastImpressions: { $each: [ ... ], $slice: -5 }}

This limits the list to the last 5 elements. The $slice value must be zero or negative.
