i am getting the error when i try to flush the data,
Warning: spl_object_hash() expects parameter 1 to be object
along with this message
Found entity of type on association Subject\Entity\Subject#user, but expecting Subject\Entity\User
now here is the action i am trying to implement
public function addAction() {
$form = new SubjectForm();
$form->get('submit')->setAttribute('label', 'Add');
$request = $this->getRequest();
if (!$this->sessionVar) {
$this->sessionVar = new SessionContainer('zftutorial');
$userid = $this->sessionVar->offsetGet('userid');
$form->get('user')->setAttribute('value', $userid);
}
$form->setData($request->getPost());
if ($request->isPost()) {
$subject = new Subject();
$form->setInputFilter($subject->getInputFilter());
if ($form->isValid()) {
$subject->populate($form->getData());
$this->getEntityManager()->persist($subject);
$this->getEntityManager()->flush();
return $this->redirect()->toRoute('subject');
}
}
return array('form' => $form);
}
and this is my subject.php
namespace Subject\Entity;

$factory = new InputFactory();
$inputFilter->add($factory->createInput(array(

)));
$inputFilter->add($factory->createInput(array(

),

),

),
)));
$inputFilter->add($factory->createInput(array(

'required' => true,
'filters' => array(
array('name' => 'Int'),
),
)));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
}
i am trying to implement oneToMany but i dont know what is wrong here.
回答1:
Ok found answer
what i was doing was wrong i was doing this
if ($request->isPost()) {
$subject = new Subject();
$form->setInputFilter($subject->getInputFilter());
if ($form->isValid()) {
$subject->populate($form->getData());
$this->getEntityManager()->persist($subject);
$this->getEntityManager()->flush();
return $this->redirect()->toRoute('subject');
}
}
Instead i had to first find the Relevant entity like this
if ($request->isPost()) {
$subject = new Subject();
//following is the line i was looking for
$user = $this->getEntityManager()->getRepository('Subject\Entity\User')->find(array('id'=>$userid));
$form->setInputFilter($subject->getInputFilter());
if ($form->isValid()) {
//$user->add
//$subject->setUser($user);
$subject->populate($form->getData());
$subject->setUser($user);
$this->getEntityManager()->persist($subject);
$this->getEntityManager()->flush();
return $this->redirect()->toRoute('subject');
}
}
