Question

你好，当我试图坚持我的实体时，我有这个错误：

An exception occurred while executing 'INSERT INTO item_details (item_id, item_type,    name, start_date, end_date, description, pre_requisites, picture, acquired_knowledges,   status) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params [null, null, "ertret",   "09\/01\/2014", "17\/01\/2014", "ter", "trtre", {}, "trtre", null]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'item_id' cannot be null

    $language=$this->get('doctrine.orm.entity_manager')->getRepository('MoocAdminBundle:Language')->findBy(array('locale'=>$locale));
    $languageId=$language[0]->getId();

    $form=$this->createForm(new CourseType($languageId));         

    if ($this->getRequest()->isMethod("POST")) {
        $form->HandleRequest($this->getRequest());    
        //if ($form->isValid()) {                
            $course = $form->getData();
            $this->get('mooc.course')->addCourse($course);                
        //}

    }

    return $this->render('MoocTeacherBundle:Default:courseadd.html.twig', array('form'=>$form->createView(),'languageId'=>$languageId));
}

服务代码：

 public function addCourse($course) {
    $details=$course->getDetails();

    $this->em->persist($course);
    /*
    foreach($course->getDetails() as $details) {
        $details->setItemType('course');
        $this->em->persist($details);

         foreach($details->getVideo() as $video) {                
            $this->em->persist($video);
        }        
    }  
   */
    $this->em->flush();
}

您需要在表格中设置ItemId：

$builder
        ->add('name')
        ->add('startDate')
        ->add('itemId') //add this line
        ->add('endDate')
        ->add('description')
        ->add('preRequisites')
        ->add('picture','file')
        ->add('acquiredKnowledges')
        ->add('status')
        ->add('video', new VideoType())
    ;

或将可空值更改为true

    /**
     * @var integer
     *
     * @ORM\Column(name="item_id", type="integer", nullable=true) //here nullable to true
     */
    private $itemId;
