Starting out with mongo-scala-driver

[Ilkka Huotari]

Hi,

I'm new so first comes a newbie question. Sorry about it.

Is there a wiki page/instructions for the first steps with mongo-scala-
driver? By first steps I mean:
- What classes to import.
- How to connect to MondoDB (database connection).
- Maybe some best practices - where to do that connection/what objects
to create for it/etc/whatever you can think of that might help a
newbie :) I'm using Play framework at the moment, so if there is any
specific things for that, it would interest of course. Generally
speaking; how to use with frameworks. (I'm not sure if this point is
important at all but throwing it in there in case it makes sense).

Thanks.

Via Java MongoDB driver: http://api.mongodb.org/java/2.3/

mongo-scala-driver is a wrapper around MongoDB Java driver, so basically you need to get an instance from Java driver and then lift it to Scala instance:

val db = mongo.getDB("mydb")
val dbCollection = db.getCollection("my_objects")
val myObjects = dboCollection of MyObjectShape

Mongo Java driver manages connection pool internally, so you can safely have a singleton "database" object and get Collection instances when you want. Or you may have Collection singletons as well.

Thank you, those helped.
