How to perform nested reference query in doctrine mongodb - php

Question

This describes my current schema:
/**
* #MongoDB\Document(repositoryClass="St\AppBundle\Repository\TaxiStateRepository", requireIndexes=true)
* #MongoDB\Index(keys={"location"="2d"})
*/
class TaxiState
{
/**
* #MongoDB\ReferenceOne(targetDocument="Taxi", simple=true, inversedBy="taxiState")
* #MongoDB\Index
*/
protected $taxi;
..
}
/**
* #MongoDB\Document(repositoryClass="St\AppBundle\Repository\TaxiRepository", requireIndexes=true)
*/
class Taxi
{
/**
* #MongoDB\ReferenceOne(targetDocument="Driver", simple=true)
* #MongoDB\Index
*/
protected $driver;
..
}
/**
* #MongoDB\Document(repositoryClass="St\AppBundle\Repository\DriverRepository", requireIndexes=true)
*/
class Driver
{
/**
* #MongoDB\EmbedOne(targetDocument="DriverAccount")
* #MongoDB\Index
*/
protected $driverAccount;
..
}
/** #MongoDB\EmbeddedDocument */
class DriverAccount
{
/**
* #MongoDB\String
* #Assert\NotBlank()
* #Assert\Choice(choices = {"enabled","disabled"}, message="please chose a valid status"); * #MongoDB\Index
*/
protected $status;
I basically want to run a query that filters out disabled driver accounts.. something like this:
return $this->createQueryBuilder()
->field('taxi.driver.driverAccount.status')->equals("enabled")
->getQuery()
->getSingleResult();
it complains that it doesn't have an index taxi.driver etc.. I spent all day looking at by directional reference documentation in doctrine but the examples are so sparse.. help?
For reference.. this was the query that worked right before i introduced that crazy line:
return $this->createQueryBuilder()
->field('status')->equals('available')
->field('taxi')->notIn($taxiObj)
->field('location')->near((float)$location->getLongitude(), (float)$location->getLatitude())
->distanceMultiplier(self::EARTH_RADIUS_KM)
->maxDistance($radius/111.12)
->getQuery()
->execute();

Answer 1

Just in case you were wondering how I "resolved" this (it's a very hacky answer.. but oh well you do what you gotta do right?) this is what I got:
/**
* Find near enabled taxi without rejected request taxi
*
* #param Document\Location $location
* #param int $radius
* #param array $taxis
* #return Document\TaxiState
*/
public function findEnabledNearTaxiWithoutRejectRequest(Document\Location $location, $radius = self::SEARCH_RADIUS, $taxis = array(), $logger)
{
$taxiObj = array_map(function ($item) {
return new \MongoId($item);
}, $taxis);
//ST-135 change to near, spherical, distanceMultiplier and maxDistance in KM
$allTaxiStates = $this->createQueryBuilder()
->field('status')->equals('available')
->field('taxi')->notIn($taxiObj)
->field('location')->near((float)$location->getLongitude(), (float)$location->getLatitude())
->distanceMultiplier(self::EARTH_RADIUS_KM)
->maxDistance($radius/111.12)
->getQuery()
->execute();
$this->addIdsOfDisabledTaxiStates($taxiObj, $allTaxiStates);
if (count($taxiObj) > 0) {
$logger->info("There are ".count($taxiObj)." taxis excluded while looking for taxis to respond to a requst: ".$this->getMongoIdsStr($taxiObj));
}
return $this->createQueryBuilder()
->field('status')->equals('available')
->field('taxi')->notIn($taxiObj)
->field('location')->near((float)$location->getLongitude(), (float)$location->getLatitude())
->distanceMultiplier(self::EARTH_RADIUS_KM)
->maxDistance($radius/111.12)
->getQuery()
->getSingleResult();
}
/**
* Get the Mongo Ids of disabled taxi States
*
* #param $ids existing array of ids we want to append to (passed by reference)
* #param $taxiStates array of Document\TaxiState
* #return array of MongoIds of disabled taxi states
* #author Abdullah
*/
private function addIdsOfDisabledTaxiStates(&$ids, $taxiStates)
{
foreach ($taxiStates as $taxiState) {
if ($taxiState->getTaxi()->getDriver()->getDriverAccount()->getStatus() != DriverAccountModel::STATUS_ENABLED) {
$mongoId = new \MongoId($taxiState->getTaxi()->getId());
array_push($ids, $mongoId);
}
}
return $ids;
}
