Bulk insert from Array in mongodb JavaScript console

Question

I'm trying to make a bulk insert from the MongoDB console of an array into a collection.

I'd like to do something similar to this.

obj1 = {_id:ObjectId(),blabla:1};

obj2 = {_id:ObjectId(),blabla:2};

objs = [obj1, obj2];

db.test.insert(objs);

db.test.find()

> {"_id": ObjectId("xxxx"), "blabla": 1} > {"_id": ObjectId("xxxx"), "blabla": 2}

But, instead of inserting two objects on the collection, it stores one list with the two objects.

db.test.find()

> {"_id": ObjectId("xxx"), "0":{"_id": ObjectId("xxxx"), "blabla": 1}, "1":{"_id": ObjectId("xxxx"), "blabla": 2} }

That functionality appears to present on other drivers (like pymongo), but I can't find a way of doing that from the mongodb console, in JavaScript code.

Answer 1

The feature to insert multiple documents into a collection has been added to Mongo command shell version 2.1+. Now You can insert and array of documents into your collection.

Example:

db.users.insert([{name:'Jon', email:'[email protected]'},{name:'Jane', email:'[email protected]'}])

For more information look at these jira closed feature request:
