php - Doctrine & Symfony2 join multiple tables -
i've been struggling doing multiple join in dql. here code:
$query = $em->createquery( 'select k appbundle:keyword k join k.company c join k.entry e c.user = :id order k.name asc' )->setparameter('id',$user_id); but gives me "notice: undefined index: entry", when executing it.
here keyword entity:
<?php namespace appbundle\entity; use doctrine\orm\mapping orm; /** * keyword */ class keyword { /** * @var integer */ private $id; /** * @var string */ private $name; /** * id * * @return integer */ public function getid() { return $this->id; } /** * set name * * @param string $name * @return keyword */ public function setname($name) { $this->name = $name; return $this; } /** * name * * @return string */ public function getname() { return $this->name; } /** * @var \doctrine\common\collections\collection */ private $user; /** * constructor */ public function __construct() { $this->user = new \doctrine\common\collections\arraycollection(); } /** * add user * * @param \appbundle\entity\user $user * @return keyword */ public function adduser(\appbundle\entity\user $user) { $this->user[] = $user; return $this; } /** * remove user * * @param \appbundle\entity\user $user */ public function removeuser(\appbundle\entity\user $user) { $this->user->removeelement($user); } /** * user * * @return \doctrine\common\collections\collection */ public function getuser() { return $this->user; } /** * set user * * @param \appbundle\entity\user $user * @return keyword */ public function setuser(\appbundle\entity\user $user = null) { $this->user = $user; return $this; } /** * @var \doctrine\common\collections\collection */ private $company; /** * add company * * @param \appbundle\entity\company $company * @return keyword */ public function addcompany(\appbundle\entity\company $company) { $this->company[] = $company; return $this; } /** * remove company * * @param \appbundle\entity\company $company */ public function removecompany(\appbundle\entity\company $company) { $this->company->removeelement($company); } /** * company * * @return \doctrine\common\collections\collection */ public function getcompany() { return $this->company; } /** * set company * * @param \appbundle\entity\company $company * @return keyword */ public function setcompany(\appbundle\entity\company $company = null) { $this->company = $company; return $this; } /** * @var \doctrine\common\collections\collection */ private $entry; /** * add entry * * @param \appbundle\entity\entry $entry * @return keyword */ public function addentry(\appbundle\entity\entry $entry) { $this->entry[] = $entry; return $this; } /** * remove entry * * @param \appbundle\entity\entry $entry */ public function removeentry(\appbundle\entity\entry $entry) { $this->entry->removeelement($entry); } /** * entry * * @return \doctrine\common\collections\collection */ public function getentry() { return $this->entry; } /** * @var \doctrine\common\collections\collection */ private $ranking; /** * add ranking * * @param \appbundle\entity\ranking $ranking * @return keyword */ public function addranking(\appbundle\entity\ranking $ranking) { $this->ranking[] = $ranking; return $this; } /** * remove ranking * * @param \appbundle\entity\ranking $ranking */ public function removeranking(\appbundle\entity\ranking $ranking) { $this->ranking->removeelement($ranking); } /** * ranking * * @return \doctrine\common\collections\collection */ public function getranking() { return $this->ranking; } } and entry entity:
<?php namespace appbundle\entity; use doctrine\orm\mapping orm; /** * entry */ class entry { /** * @var integer */ private $id; /** * @var string */ private $path; /** * id * * @return integer */ public function getid() { return $this->id; } /** * set path * * @param string $path * @return entry */ public function setpath($path) { $this->path = $path; return $this; } /** * path * * @return string */ public function getpath() { return $this->path; } /** * @var \appbundle\entity\keyword */ private $keyword; /** * set keyword * * @param \appbundle\entity\keyword $keyword * @return entry */ public function setkeyword(\appbundle\entity\keyword $keyword = null) { $this->keyword = $keyword; return $this; } /** * keyword * * @return \appbundle\entity\keyword */ public function getkeyword() { return $this->keyword; } /** * @var \doctrine\common\collections\collection */ private $ranking; /** * constructor */ public function __construct() { $this->ranking = new \doctrine\common\collections\arraycollection(); } /** * add ranking * * @param \appbundle\entity\ranking $ranking * @return entry */ public function addranking(\appbundle\entity\ranking $ranking) { $this->ranking[] = $ranking; return $this; } /** * remove ranking * * @param \appbundle\entity\ranking $ranking */ public function removeranking(\appbundle\entity\ranking $ranking) { $this->ranking->removeelement($ranking); } /** * ranking * * @return \doctrine\common\collections\collection */ public function getranking() { return $this->ranking; } } btw i'm pretty new symfony , doctrine. appreciate kinds of help!
you need provide mapping information each attribute in model class provide entity mapping class. take @ http://doctrine-common.readthedocs.org/en/latest/reference/annotations.html
each of model classes need @orm\entity annotation tell doctrine mapped entity. case have:
/** * entry * @orm\entity */ class entry { ... then each attribute want mapped database needs @orm\column annotation. example:
/** * @var integer * @orm\id @orm\column @orm\generatedvalue */ private $id; /** * @var string * @orm\column(type="string") */ private $path; then need create relationship mapping annotations relationships between models (keyword -> company, keyword -> entry etc), using 1 of mappings on here http://doctrine-orm.readthedocs.org/en/latest/reference/association-mapping.html
once have correct mappings use command line tool app/console doctrine:schema:update make sure model in sync database.
your dql seems fine once have correct mappings in place might have better luck.
