这是我的第一个问题所以我希望我能做到应有的一切。
我有2个具有多对多关系的学说实体,并且工作正常,但我还想在多对多表上添加额外的检查。问题是在DQL中我无法进入正确的列。
我想到了两种可能性:抽象父类或本机查询。 我将粘贴下面有效的本机查询,但这不是我希望的,因为我们必须复制并粘贴它。
所以我想建立关系+类型。所以对于这个例子,我还需要检查type ='Gallery'
gallery_object(表)
id,tag,deleted
1,赞助商,0
media_relations(表)
id,mediaid,type,typeId
1,37,画廊,1
media_files
id,userid,filename,filepath,filesize,mime_type,date,deleted
37,4,533882_10151332524797037_1940030593_n_20.jpg,/ resources / upload / www /,82724,image / jpeg,2013-01-25 15:04:46,0
$rsm = new ResultSetMapping;
$rsm->addEntityResult(Helper::getNamespace('Gallery', 'Models/Entities') . "Object", 'o')
->addFieldResult('o', 'id', 'id')
->addFieldResult('o', 'tag', 'tag')
->addFieldResult('o', 'deleted', 'deleted')
->addJoinedEntityResult(ltrim(Helper::getNamespace('Media', 'Models/Entities') . "Media", '\\'), 'm', 'o', 'file')
->addFieldResult('o', 'file', 'id')
->addFieldResult('m', 'mid', 'id')
->addFieldResult('m', 'user', 'userid')
->addFieldResult('m', 'filename', 'filename')
->addFieldResult('m', 'filepath', 'filepath')
->addFieldResult('m', 'filesize', 'filesize')
->addFieldResult('m', 'mime_type', 'mime_type')
->addFieldResult('m', 'date', 'date')
->addFieldResult('m', 'mdeleted', 'deleted');
$sql = "SELECT o.id AS oid, m.id as file, o.tag, o.deleted, m.id AS mid, m.userid, m.filename, m.filepath, m.filesize, m.mime_type, m.date, m.deleted as mdeleted
FROM gallery_object as o
INNER JOIN media_relations mr ON (mr.typeid = o.id AND mr.type = 'Gallery')
INNER JOIN media_files m ON (mr.mediaid = m.id)";
$result = $this->_em->createNativeQuery($sql, $rsm)->getResult();
return $result;
实体看起来像
/**
* Media entity
*
* @Entity(repositoryClass = "iTet\Application\Modules\Media\Models\Repositories\Media")
* @Table(name="media_files")
* @author Stephen Fenne
*/
class Media
{

答案 0 :(得分:0)
根据我的意见,您的选择如下:
media_relations
表中的条目,以及与其他表的适当关联。在这两种情况下,您都会将基础表暴露给Doctrine,以便您可以使用DQL来获取所需的数据。
