Symfony2来自第一实体表中第二实体形式的安全数据

Question

how can I save the data from my created form , which is using 2 entitys to output different select and input fields, into the table of the first entity.

Main Entity is Tasks.php - in this form I get also data from 2 other Entities called TaskTypes and User.

It looks like this:

$AddTask = new Tasks();
$form = $this->createFormBuilder($AddTask)
    ->add('task_title', 'text', array('label' => 'Aufgabentitel', 'attr' => array('class' => 'first')))
    ->add('task_description', 'textarea', array('label' => 'Aufgabenbeschreibung'))
    ->add('task_types', 'entity', array(
        'class' => 'SeotoolMainBundle:TaskTypes',
        'property' => 'task_type_title',
        'label' => 'Aufgabentyp'))

    ->add('user', 'entity', array(
        'class' => 'SeotoolMainBundle:User',
        'property' => 'username',
        'label' => 'Kundenzuordnung',
        'query_builder' => function(EntityRepository $er ) use ( $request ) {
                return $er->createQueryBuilder('w')
                    ->orderBy('w.username', 'ASC')
                    ->where('w.isAdmin = 0')
                    ->andWhere('w.isActive = 1');
        }
    ))
    ->add('Aufgabe anlegen', 'submit')
    ->getForm();
$form->handleRequest($request);

if ($form->isValid()) {


    $task = new Tasks();
    $task->setTaskTitle($request->request->get('form')['task_title']);
    $task->setTaskDescription($request->request->get('form')['task_description']);

    $em = $this->getDoctrine()->getManager();
    $em->persist($task);
    $em->flush();

    return $this->redirect($this->generateUrl('add_task'));

}

My Entity/Tasks.php looks like this:

...
/**
 * @Assert\Type(type="Seotool\MainBundle\Entity\TaskTypes")
 */
protected $tasktypes;

/**
 * @Assert\Type(type="Seotool\MainBundle\Entity\User")
 */
protected $user;
...
    public function getTaskTypes()
{
    return $this->tasktypes;
}

public function setTaskTypes(TaskTypes $tasktypes = null)
{
    $this->tasktypes = $tasktypes;
}

public function getUser()
{
    return $this->user;
}

public function setUser(User $user = null)
{
    $this->user = $user;
}

I got these code snippets out of an example how to make forms with multiple entities. But I don't get it working to save the data from the "extern entity" in the table of the "main entity"

What I tried:

...
   /**
 * @Assert\Type(type="Seotool\MainBundle\Entity\TaskTypes")
 * @ORM\Column(type="integer")
 */
protected $tasktypes;

/**
 * @Assert\Type(type="Seotool\MainBundle\Entity\User")
 * @ORM\Column(type="string")
 */
protected $user;

....

public function getTaskTypes()
{
    return $this->tasktypes;
}

public function setTaskTypes()
{
   return $this->tasktypes;
}

public function getUser()
{
    return $this->user;
}

public function setUser(User $user = null)
{
    $this->user = $user;
}

It outputs following error:

Neither the property "task_types" nor one of the methods "addTaskTyp()"/"removeTaskTyp()", "addTaskType()"/"removeTaskType()", "setTaskTypes()", "taskTypes()", "__set()" or "__call()" exist and have public access in class "Seotool\MainBundle\Entity\Tasks". 500 Internal Server Error - NoSuchPropertyException

Answer 1

There is a discrepancy between your property names, and the getter and setter methods. Regenerate your getters and setters to ensure that they are matched correctly.

As it stands, you will not be able to add a null value into the task_type field in the database. To change this, you can declare it in your annotation:

@ORM\Column(type="integer", nullable=true) 

And then update the database schema.
