javascript - Mongoose update multiple documents

Question

Actually i am using mongoDB, and i am able to update document with single ObjectID, so right now i want to perform update on multiple documents having different ObjectID, i did considerable search, came to know {multi:true} will help to update multiple documents. Let's say i have

var uid = {'Userid': ObjectId(..)};
var id = {'Newid': Object(..)};

now i want to perform update on both of these different documents having different ObjectId' s total separatley, so far i tried this considering "xyz" and "abc" array's in Schema just for demo

var update_uid = {$push:{'xyz': some_id}};
var update_id = {$push:{'abc': some_other_id}};

Test.update(uid,id,update_uid,update_id,{multi:true},function(){..});

this is wrong i know, i mentioned it for the records just in case, Any help and suggestion would be much appreciated

If you have multiple ids that you want to match you can use the keywork $in which checks if there's any matches in the array. Now that you also have multiple properties that you want to check you can user the $or keyword, which will find a match if either of the objects in the array matches a document in the database.

var userIds = [{'Userid':ObjectId(..)}, {'Userid':ObjectId(..)}];
var newIds = [{'Newid': Object(..)}, {'Newid': Object(..)}];

var query = {
  $or: [{$in: userIds}, {$in: newIds}]
}
