Mongoose, update values in array of objects

Is there a way to update values in an object? ``` { _id: 1, name: 'John Smith', items: [{ id: 1, name: 'item 1', value: 'one' },{ id: 2, name: 'item 2', value: 'two' }] } ``` Lets say I want to update the name and value items for item where id = 2; I have tried the following w/ mongoose: ``` var update = {name: 'updated item2', value: 'two updated'}; Person.update({'items.id': 2}, {'$set': {'items.$': update}}, function(err) { ... ``` Problem with this approach is that it updates/sets the entire object, therefore in this case I lose the id field. Is there a better way in mongoose to set certain values in an array but leave other values alone? I have also queried for just the Person: ``` Person.find({...}, function(err, person) { person.items ..... // I might be able to search through all the items here and find item with id 2 then update the values I want and call person.save(). }); ```
