我在网站上实施搜索，为了简单起见，我决定创建一个能够完成艰苦工作的课程。
基本上我的类使用EntityManager和我想要搜索的实体并创建DQL并执行查询。对于普通实体，这工作完全正常但是当我传递User实体（从fos用户包实体扩展）时，我收到此错误：
[语义错误]第0行，第139行附近＆＃39; last_login LIKE＆＃39;：错误：类Soundmerger \ UserBundle \ Entity \ User没有名为last_login的字段或关联
生成的dql查询似乎很好，因为它适用于其他实体，我怀疑它来自那里。
这是我的搜索类：
use Doctrine\Common\Util\Debug;
use Doctrine\ORM\EntityManager;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Query;
class Search {
private $em;
private $searchables;
public function __construct(EntityManager $em, ArrayCollection $searchables){
$this->em = $em;
$this->searchables = $searchables;
}
public function search($query){
$words = explode("+", $query);
$qb = array();
$results = array();
foreach($this->searchables as $qNumber => $searchable){
$qb[$qNumber] = "SELECT s FROM $searchable s ";
$columns = $this->em->getClassMetadata($searchable)->getColumnNames();
foreach($words as $i => $word){
foreach($columns as $k => $column){
$string = "s.$column LIKE '%$word%'";
if($i == 0 && $k == 0){
$qb[$qNumber] .= "WHERE $string";
} else {
$qb[$qNumber] .= "OR $string";
}
}
}
$res[] = $this->em->createQuery($qb[$qNumber])->getResult(Query::HYDRATE_SIMPLEOBJECT);
}
return $this->formatSearch($res);
}
private function formatSearch($results){
$formatedResult = array();
foreach($results as $k => $result){
if(!empty($result)){
$formatedResult[$k]["type"] = get_class($result[0]);
$formatedResult[$k]["data"] = $result[0];
}
}
return $formatedResult;
}
}
我的搜索控制器：
/**
* @Route("/search/{query}")
* @Template()
*/
public function indexAction($query)
{
$em = $this->getDoctrine()->getManager();
$searchables = new ArrayCollection(
array(
"SoundmergerUserBundle:Professional",
"SoundmergerFaqBundle:Faq",
"SoundmergerUserBundle:User",
));
$search = new Search($em, $searchables);
return array('search' => $search->search($query));
}
最后是我的用户实体：
/**
* @ORM\Entity
* @ORM\Table(name="fos_user")
* @AttributeOverrides({
* @AttributeOverride(name="emailCanonical",
* column=@ORM\Column(
* name = "emailCanonical",

* length = 255,
* nullable = true
* )
* ),
* @AttributeOverride(name="email",
* column=@ORM\Column(
* name = "email",
* type = "string",
* length = 255,
* nullable = true
* )
* ),

* column=@ORM\Column(

关于为什么这只发生在用户实体上的任何想法（它必须归因于继承，但我似乎无法找到解决方法）
顺便说一下：它是一个大学项目，因此使用外部捆绑进行搜索的想法实际上是不可能的。感谢您的帮助
