php - Getting strange data after adding a foreign constraint in symfony 3.3 -
i have 2 simple entities in app:product , category related manytoone relation:
<?php namespace appbundle\entity; use doctrine\orm\mapping orm; /** * product * * @orm\table(name="product") * @orm\entity */ class product { /** * @var int * * @orm\column(name="id", type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ private $id; /** * @var string * * @orm\column(name="name", type="string", length=255) */ private $name; /** * @var string * * @orm\column(name="description", type="text") */ private $description; /** * @orm\manytoone(targetentity="category", inversedby="products") * @orm\koincolumn(ondelete="cascade") */ private $category; /** * id * * @return int */ public function getid() { return $this->id; } /** * set name * * @param string $name * * @return product */ public function setname($name) { $this->name = $name; return $this; } /** * name * * @return string */ public function getname() { return $this->name; } /** * set description * * @param string $description * * @return product */ public function setdescription($description) { $this->description = $description; return $this; } /** * description * * @return string */ public function getdescription() { return $this->description; } /** * @return int */ public function getcategory() { return $this->category; } /** * @param int $category */ public function setcategory($category) { $this->category = $category; } } /** * category * * @orm\table(name="category") * @orm\entity */ class category { /** * @var int * * @orm\column(name="id", type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ private $id; /** * @var string * * @orm\column(name="name", type="string", length=255) */ private $name; /** * id * * @return int */ public function getid() { return $this->id; } /** * set name * * @param string $name * * @return category */ public function setname($name) { $this->name = $name; return $this; } /** * name * * @return string */ public function getname() { return $this->name; } } the relation working fine.but there problem.when try fetch objects db
public function indexaction(){ $products = $this->getdoctrine() ->getrepository('appbundle:product') ->findall(); echo "<pre>"; print_r($products);die; } it returns tone of code, like:
array ( [0] => appbundle\entity\product object ( [id:appbundle\entity\product:private] => 1 [name:appbundle\entity\product:private] => samsung galaxy s5 [description:appbundle\entity\product:private] => stylish , elegant! [category:appbundle\entity\product:private] => proxies\__cg__\appbundle\entity\category object ( [__initializer__] => closure object ( [static] => array ( [entitypersister] => doctrine\orm\persisters\entity\basicentitypersister object ( [class:protected] => doctrine\orm\mapping\classmetadata object ( [name] => appbundle\entity\category [namespace] => appbundle\entity [rootentityname] => appbundle\entity\category [customgeneratordefinition] => [customrepositoryclassname] => [ismappedsuperclass] => [isembeddedclass] => [parentclasses] => array ( ) [subclasses] => array ( ) [embeddedclasses] => array ( ) [namedqueries] => array ( ) [namednativequeries] => array ( ) [sqlresultsetmappings] => array ( ) and lot more, unpossible present here entirely. appreciate if suggests me how rid of unnecessary data , recieve object's properties. in advance.
that happens because doctrine default loads associations proxies references real entities. when try fetch association, doctrine fetches data database , hydrates it. commonly called lazy loading , useful performance improving.
to solve have set eager fetch mode on association:
/** * @orm\manytoone(targetentity="category", inversedby="products", fetch="eager") */ private $category;
