Is there any way to perform bulk updates on ReactiveMongo?

Question

Suppose I want to do the following (in mongo shell):

var bulk = db.vectors.initializeOrderedBulkOp()

bulk.find({\"_id\" : ObjectId(\"53f265da13d3f885ed8bf75d\")         


        

Answer 1

I am using reactive-mongo 0.11.9:

import collection.BatchCommands._
import UpdateCommand._ 
import reactivemongo.bson._

collection.runCommand(Update(
  UpdateElement(q = document(...), u = document(...)), 
  UpdateElement(q = document(...), u = document(...))...
))

Answer 2

I found the answer! ReactiveMongo has RawCommand command that let us run any MongoDB command (like update, in this case >> http://docs.mongodb.org/manual/reference/command/update/#dbcmd.update):

  val commandDoc =
        BSONDocument(
          "update" -> COLLECTION,
          "updates" -> BSONArray(
            BSONDocument("q" -> <query>, "u" -> BSONDocument("$pop" -> BSONDocument("v" -> 1))),
            BSONDocument("q" -> <query>, "u" -> BSONDocument("$push" -> BSONDocument("v" -> 5)))
          ),
          "ordered" -> true
        )

      // we get a Future[BSONDocument]
      val futureResult = db.command(RawCommand(commandDoc))

      futureResult.map { result => // result is a BSONDocument
           //...
      }
