Scala, Casbah: MongoCollection.insert compilation errors

Question

I am trying to write function that writes data to MongoDB using Casbah toolkit:

  import com.mongodb.casbah.WriteConcern
      import ...

  def saveRecord(rec: MongoDBObject) {
    mongoColl.insert(rec)
  }

I get the following errors:

1) No implicit view available from Object => com.mongodb.casbah.Imports.DBObject.   

2) not enough arguments for method insert: (implicit dbObjView: Object => com.mongodb.casbah.Imports.DBObject, implicit concern: com.mongodb.WriteConcern, implicit encoder: com.mongodb.casbah.Imports.DBEncoder)com.mongodb.casbah.Imports.WriteResult. Unspecified value parameter dbObjView.

What's wrong?

I'm not sure without full imports, but try to change MongoDBObject to com.mongodb.DBObject or add import com.mongodb.casbah.Imports._

Thanks, this one works. But for some reason `import com.mongodb.casbah._` does not. Why? – Anton Ashanin Mar 31 '13 at 11:08
`import com.mongodb.casbah._` imports package, but `import com.mongodb.casbah.Imports._` imports object `Imports` which contains all implicits and type aliases for casbah. – Sergey Passichenko Mar 31 '13 at 11:11
Does it mean that package import does not import object definitions? – Anton Ashanin Mar 31 '13 at 11:17
It allows you to use objects and classes without package prefix, but it's not recursive, so you need to directly import object `Import` if you want to use it's content. – Sergey Passichenko Mar 31 '13 at 12:24
