i have file /src/appbundle/entity/questionnaire.php 3 entity classes, i'm trying implement single table inheritance doctrine 2 on symfony 2.7. questionnaire parent abstract class, , there 2 child classes firstquestions , secondsquestions extends questionnaire. choosed model because need write data in table in 2 steps. code of file below:
namespace appbundle\entity; use doctrine\orm\mapping orm; /** * questionnaire * * @orm\entity * @orm\table(name="questionnaire") * @orm\inheritancetype("single_table") * @orm\discriminatorcolumn(name="discr", type="string") * @orm\discriminatormap({"firstquestions" = "firstquestions", "secondquestions" = "secondquestions"}) */ abstract class questionnaire { /** * @var integer * * @orm\column(name="id", type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ private $id; /** * id * * @return integer */ public function getid() { return $this->id; } } /** * firstquestions */ class firstquestions extends questionnaire { /** * @var string * * @orm\column(name="firstname", type="string", length=64) */ private $firstname; /** * @var string * * @orm\column(name="lastname", type="string", length=64) */ private $lastname; /** * @var string * * @orm\column(name="email", type="string", length=32) */ private $email; /** * @var \datetime * * @orm\column(name="birthday", type="date") */ private $birthday; /** * @var integer * * @orm\column(name="shoesize", type="integer") */ private $shoesize; /** * set firstname * * @param string $firstname * * @return questionnaire */ public function setfirstname($firstname) { $this->firstname = $firstname; return $this; } /** * firstname * * @return string */ public function getfirstname() { return $this->firstname; } /** * set lastname * * @param string $lastname * * @return questionnaire */ public function setlastname($lastname) { $this->lastname = $lastname; return $this; } /** * lastname * * @return string */ public function getlastname() { return $this->lastname; } /** * set email * * @param string $email * * @return questionnaire */ public function setemail($email) { $this->email = $email; return $this; } /** * email * * @return string */ public function getemail() { return $this->email; } /** * set birthday * * @param \datetime $birthday * * @return questionnaire */ public function setbirthday($birthday) { $this->birthday = $birthday; return $this; } /** * birthday * * @return \datetime */ public function getbirthday() { return $this->birthday; } /** * set shoesize * * @param integer $shoesize * * @return questionnaire */ public function setshoesize($shoesize) { $this->shoesize = $shoesize; return $this; } /** * shoesize * * @return integer */ public function getshoesize() { return $this->shoesize; } } /** * secondquestions */ class secondquestions extends questionnaire { /** * @var string * * @orm\column(name="favoriteicecream", type="string", length=128) */ private $favoriteicecream; /** * @var string * * @orm\column(name="favoritesuperhero", type="string", length=32) */ private $favoritesuperhero; /** * @var string * * @orm\column(name="favoritemoviestar", type="string", length=64) */ private $favoritemoviestar; /** * @var \datetime * * @orm\column(name="endoftheworld", type="date") */ private $endoftheworld; /** * @var string * * @orm\column(name="superbowlwinner", type="string", length=32) */ private $superbowlwinner; /** * set favoriteicecream * * @param string $favoriteicecream * * @return questionnaire */ public function setfavoriteicecream($favoriteicecream) { $this->favoriteicecream = $favoriteicecream; return $this; } /** * favoriteicecream * * @return string */ public function getfavoriteicecream() { return $this->favoriteicecream; } /** * set favoritesuperhero * * @param string $favoritesuperhero * * @return questionnaire */ public function setfavoritesuperhero($favoritesuperhero) { $this->favoritesuperhero = $favoritesuperhero; return $this; } /** * favoritesuperhero * * @return string */ public function getfavoritesuperhero() { return $this->favoritesuperhero; } /** * set favoritemoviestar * * @param string $favoritemoviestar * * @return questionnaire */ public function setfavoritemoviestar($favoritemoviestar) { $this->favoritemoviestar = $favoritemoviestar; return $this; } /** * favoritemoviestar * * @return string */ public function getfavoritemoviestar() { return $this->favoritemoviestar; } /** * set endoftheworld * * @param \datetime $endoftheworld * * @return questionnaire */ public function setendoftheworld($endoftheworld) { $this->endoftheworld = $endoftheworld; return $this; } /** * endoftheworld * * @return \datetime */ public function getendoftheworld() { return $this->endoftheworld; } /** * set superbowlwinner * * @param string $superbowlwinner * * @return questionnaire */ public function setsuperbowlwinner($superbowlwinner) { $this->superbowlwinner = $superbowlwinner; return $this; } /** * superbowlwinner * * @return string */ public function getsuperbowlwinner() { return $this->superbowlwinner; } } so problem when i'm trying create object of child class(firstquestions or secondsquestions) in method of controller, symfony displays me error "500 internal server error". code of controller method below:
namespace appbundle\controller; use symfony\bundle\frameworkbundle\controller\controller; use sensio\bundle\frameworkextrabundle\configuration\route; use symfony\component\httpfoundation\response; use symfony\component\httpfoundation\request; use appbundle\entity\questionnaire; use appbundle\entity\firstquestions; use appbundle\entity\secondquestions; class testcontroller extends controller { /** * @route("/test", name="test") */ public function indexaction(request $request) { $item = new firstquestions(); // works without line return new response( 'ok' ); } } maybe doing wrong or didn't set important annotation. can me?
this 1 of annoying little oversight errors - semi-colon or somewhere you're not looking it. i'm creating additional answer can give code i'm using. hopefully, you'll able cut-and-paste, replace own files new code, , magically start working.
first - prove point, here's (modified) output:
veromo\bundle\corebundle\entity\firstquestions object ( [firstname:veromo\bundle\corebundle\entity\firstquestions:private] => [lastname:veromo\bundle\corebundle\entity\firstquestions:private] => [email:veromo\bundle\corebundle\entity\firstquestions:private] => [birthday:veromo\bundle\corebundle\entity\firstquestions:private] => [shoesize:veromo\bundle\corebundle\entity\firstquestions:private] => [id:veromo\bundle\corebundle\entity\questionnaire:private] => ) which shows i'm doing differently using own dev environment's namespaces.

app\config\routing.yml
test: resource: "@appbundle/controller/testcontroller.php" type: annotation it's got stupid, annoying little error nobody looking for.
hope helps ...
