How to select certain fields with mongodb doctrine in symfony2

I want to find some documents from my mongo Database, and I’m using the function : FindBy() unfortunately this function doesn’t have any field selection arguments like native mongodb driver has with the function : find(). Does any one know how to select custom fields in the doctrine of Mongodb ? Thanks

Answer

You will need to use QueryBuilder with the select operator:

$result = $dm->createQueryBuilder('User')->select('field1', 'field2')->field('field3')->equals('somevalue')->getQuery()->execute();
