How can i update multiple documents in mongoose

Question

I found the following script:

Device.find(function(err, devices) {
  devices.forEach(function(device) {
    device.cid = '';
    device.save();
  });
});

MongoDB has the "multi" flag for an update over multiple documents but I wasn't able to get this working with mongoose. Is this not yet supported or am I doing something wrong?!

Device.update({}, {cid: ''}, false, true, function (err) {
  //...
});

Hello @kartik,

Use:

Device.updateMany({}, { cid: '' });

Hope it works!!
