How to get all objects in a Mongodb collection, including identifiers?

I use Casbah and Salat to create my own Mongodba Dao and I implement the getAll method as follows:

val dao: SalatDAO[T, ObjectId]    
def getAll(): List[T] = dao.find(ref = MongoDBObject()).toList

What I want to know:

  • Is there a better way to get all objects?
  • When I repeat the objects, I cannot find the _id object. Is this out of the question? How to include it in the list?

, SalatMongoCursor[T], dao.find, ( toList from Iterator, List[T]).
