Question

doeas anybody use the Query\Builder from Doctrine as Standalone Tool ?

It seems like The Query Manager needs a defined
Class of the requested Document in MongoDB.

If you have a defined Class like:

<?php

namespace Documents;

/** @Document */
class User
{
    // ...

    /** @Field(type="string") */
    private $username;
}

Then you can do the following:

<?php

$user = $dm->createQueryBuilder('User')
    ->field('username')->equals('jwage')
    ->getQuery()
    ->getSingleResult();

Is there a way to do use the Query\Builder without defining the Document Classes ?

Thanks in advance for any help.

Answer 1

You can use the QueryBuilder as soon as you have ClassMetaData.
This class metadata is about mapping class properties to internal information, such as data types, associations, …

You can define this class metadata without having real classes.
There are different approaches, but one of them would be to use the Doctrine\ODM\MongoDB\Tools\DisconnectedClassMetadataFactory class, and feed related information using yaml or xml mapping.

You will have to configure your DocumentManager with the good classMetadataFactoryName option.
