wish help you to fix your issue There is a bug in your for loop, it currently queries for "_id":0,"_id":1,etc. You need to change var style_name = [i] to this:
code :
 var style_name = new_styles[i];

With these it helps By default mongo only updates the first row it finds, to make it update multiple matching rows you need to pass the "multi" update option. In scala I believe it would look something like this:
Document.update( ("room" -> "test") ~ ("module" -> "item"), ("$set" -> ("active" -> 0)), Multi )

I hope this helps you . You cannot modify multiple array elements in a single update operation. Thus, you'll have to repeat the update in order to migrate documents which need multiple array elements to be modified. You can do this by iterating through each document in the collection, repeatedly applying an update with $elemMatch until the document has all of its relevant comments replaced, e.g.:
code :
db.collection.find().forEach( function(doc) {
  do {
    db.collection.update({_id: doc._id,
                          comments:{$elemMatch:{user:"test",
                                                avatar:{$ne:"new_avatar.jpg"}}}},
                         {$set:{"comments.$.avatar":"new_avatar.jpg"}});
  } while (db.getPrevError().n != 0);
})

fixed the issue. Will look into that further You seem to have your functions mixed around even though I clearly see what you are trying to do.
Your batch you are passing in contains an array of documents that you want to insert/update. The problem is that this functionality is only available to the insert method.

hop of those help? The below command work great, and can do the required operation as needed, considering you have a list of users' ids or names you want to update (may be all)
code :
db.salaries.aggregate( [ {$match : { _id:{$in:[ObjectId("563e1d9d04aa90562201fd5f"),ObjectId("564657f88f71450300e1fe0b")]}  } } , {$project: { rating: {$divide:["$metric_1","$metric_2"]} } } , {$out:"new_salaries"} ] )
var salaries_to_update = db.salaries.aggregate( [ {$match : { _id:{$in:[ObjectId("563e1d9d04aa90562201fd5f"),ObjectId("564657f88f71450300e1fe0b")]}  } } , {$project: { rating: {$divide:["$metric_1","$metric_2"]} } } ] )
var bulk = db.salaries.initializeUnorderedBulkOp()

salaries_to_update.forEach(salary){
    bulk.find( _id: salary._id).updateOne({$set:{salary:salary.salary}})
}

bulk.execute()
