MongoDB Update (Insert a List of Item to an Array)

Question

I want to add several items to arrays of several rows in Mongo. How can I do this?

I want to start with this:

{\'x\': \'h\', arr: [1,2,3] }
{\'x\':          


        

Answer 1

$pushAll
Deprecated since version 2.4: Use the $push operator with $each instead.

The $pushAll operator appends the specified values to an array.

The $pushAll operator has the form:

{ $pushAll: { : [ , , ... ] } }

If you specify a single value, $pushAll will behave as $push.
