Doctrine MongoDB 在没有 ODM 的情况下使用

Question

I am using Doctrine MongoDB within Symfony2, but now I want to do some things which for me are easier without the ODM, how can I get the MongoClient or MongoCollection object?

I want to use MongoDB in the old-fashioned way like: http://php.net/manual/en/mongocollection.find.php

Answer 1

You can get the MongoClient from the DocumentManager using

$mongoClient = $dm->getConnection()->getMongo();

Similarly, you can get a MongoCollection instance for document class className using

$mongoCollection = $dm->getDocumentCollection('className')->getMongoCollection();

or more simply

$mongoCollection = $dm->getConnection()->getMongo()
    ->selectCollection('collectionName');
