如何在Doctrine2 QueryBuilder上合并多个实体
[英]How can I hydrate multiple entities on Doctrine2 QueryBuilder
问题描述
I have a symfony2 application using Doctrine2, and some entities for City, State, Country, Address. 
我有一个使用Doctrine2的symfony2应用程序，以及一些用于城市，州，国家/地区，地址的实体。
The problem is that if I do this: 问题是，如果我这样做：
$queryBuilder = $this->em->createQueryBuilder();
$queryBuilder
->select(array('country', 'state', 'city', 'address'))
->from('CouponiacsMainBundle:Country', 'country')
->leftJoin('country.states', 'state', 'WITH', 'state.name=:stateName OR state.shortName=:stateShortName')
->leftJoin('state.cities', 'city', 'WITH', 'city.name=:cityName')
->leftJoin('city.addresses', 'address', 'WITH', 'address.address=:address AND address.zip=:zip AND address.latitude=:latitude AND address.longitude=:longitude')
->where('country.name=:countryName OR country.shortName=:countryShortName')
->orderBy('city.name', 'DESC')
->setParameters(array(
'countryName' => $country,
'countryShortName' => $countryShort,
'stateName' => $state,
'stateShortName' => $stateShort,
'cityName' => $city,
'address' => $address['address'],
'zip' => $address['zip'],
'latitude' => $address['latitude'],
'longitude' => $address['longitude'],
))
->setMaxResults(1);
the resultset contains only the Country entity, but no State entity. 结果集仅包含“国家”实体，而没有“州”实体。 I have also tried the same query using DQL with no success: 我也尝试使用DQL进行相同的查询，但没有成功：
$query = $this->em->createQuery('SELECT country, state, city, address
FROM CouponiacsMainBundle:Country country
LEFT JOIN country.states state WITH state.name=:stateName OR state.shortName=:stateShortName
LEFT JOIN state.cities city WITH city.name=:cityName
LEFT JOIN city.addresses address WITH address.address=:address AND address.zip=:zip AND address.latitude=:latitude AND address.longitude=:longitude
WHERE country.name=:countryName OR country.shortName=:countryShortName
ORDER BY city.name DESC
')->setParameters(array(
'countryName' => $country,
'countryShortName' => $countryShort,
'stateName' => $state,
'stateShortName' => $stateShort,
'cityName' => $city,
'address' => $address['address'],
'zip' => $address['zip'],
'latitude' => $address['latitude'],
'longitude' => $address['longitude'],
));
If I manually run the generated SQL, the result for state is ok, but on the resultset there is no entity for state. 如果我手动运行生成的SQL，则状态的结果可以，但是在结果集上没有状态的实体。 The result is an array with Country entity, and if I do getStates() I get no states. 结果是一个具有Country实体的数组，如果我执行getStates（），则不会获得任何状态。
Any suggestions are appreciated, Thanks! 任何建议表示赞赏，谢谢！

The problem is likely that you are using some of these entities before in other queries. 问题可能是您在其他查询中先使用了其中一些实体。 And Doctrine keeps some of that stuff cached. 而Doctrine则保留了其中的一些东西。 It depending on if the associations are fully loaded or only partially. 这取决于关联是完全加载还是仅部分加载。 Loading a fresh entity manager or another entity manager should do the trick. 加载新的实体经理或其他实体经理应该可以解决问题。
