データをフラッシュしようとするとエラーが発生します。

警告: spl_object_hash() は、パラメーター 1 がオブジェクトであることを想定しています

このメッセージと共に

関連付け Subject\Entity\Subject#user でタイプのエンティティが見つかりましたが、Subject\Entity\User が必要です

今ここに私が実装しようとしているアクションがあります

 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);
}

これは私のsubject.phpです

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

                    ),
                )));



        $this->inputFilter = $inputFilter;
    }



    return $this->inputFilter;
}

}

oneToMany を実装しようとしていますが、ここで何が問題なのかわかりません。

わかりました答えが見つかりました

私がしていたことは間違っていた 私はこれをしていた

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');
    }
}

代わりに、最初にこのような関連エンティティを見つける必要がありました

 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');
        }
    }
