node.js - Problems with multiple update in MongoDb -

-

i have mongo structure this:

{         "_id" : objectid("51596b7e469b9c3816000001"),         "company" : {                 "_id" : "ade2fd0ec9b8b5e9152e0155",                 "title" : "lo3426546457"         }, } {         "_id" : objectid("51596cef469b9c3816000008"),         "company" : {                 "_id" : "ade2fd0ec9b8b5e9152e0155",                 "title" : "lo3426546457"         }, } {         "_id" : objectid("51596cc3469b9c3816000007"),         "company" : {                 "_id" : "ade2fd0ec9b8b5e9152e0155",                 "title" : "lo3426546457"         }         }

and want change 'title' fields objects specific '_id'. this:

collections.userscollection.update({     'company._id': 'ade2fd0ec9b8b5e9152e0155' }, {     $set: {         'company': { _id: 'ade2fd0ec9b8b5e9152e0155', title: 'blablabla' }         // tried: 'company.title': 'blablabla'     } }, false, true);

and after execution code in node.js (i use node-mongodb-native), mongo updates only one document.

but if command @ mongo shell (mongo.exe), works fine , updates documents.

what's problem?

by default mongo updates single document. http://docs.mongodb.org/manual/reference/method/db.collection.update/

use multi option multiple document update.
