如何解决EmbedMany表格

| 我已经创建了一个小型的Symfony2-Web站点（使用Symfony PR11），并将MongoDB作为数据库。我可以创建一个使用普通文档的表单，但是如何使用带有EmbeddedDocument的文档？以下是文件：

/**
 * @mongodb:Document(collection=\"location\")
 */
class Location
{
    /**
     * @mongodb:Id
     */
    protected $id;

    /**
     * @mongodb:String
     */
    protected $locationName;

    /**
     * @mongodb:EmbedMany(targetDocument=\"LocationTerminal\")
     */
    protected $terminals = array();

    // Setter

    public function setTerminals(LocationTerminal $terminal)
    {
        array_push($this->terminals,$terminal);
    }

    public function setLocationName($locationName)
    {
        $this->locationName = $locationName;
    }


    // Getter

    public function getId()
    {
        return $this->$id;
    }

    public function getLocationName()
    {
        return $this->locationName;
    }

    public function getTerminals()
    {
        return $this->terminals;
    }

}

EmbeddedDocument：

/**
 * @mongodb:EmbeddedDocument
 */
class LocationTerminal
{
    /**
     * @mongodb:String
     */
    protected $terminalName;

    /**
     * @mongodb:Int
     */
    protected $since;

    /**
     * @mongodb:Int
     */
    protected $to;

    // Setter

    public function setTerminalName($terminalName)
    {
        $this->terminalName = $terminalName;
    }

    public function setSince($since)
    {
        $this->since = $since;
    }

    public function setTo($to)
    {
        $this->to = $to;
    }

    // Getter

    public function getTerminalName()
    {
        return $this->terminalName;
    }

    public function getSince()
    {
        return $this->since;
    }

    public function getTo()
    {
        return $this->to;
    }

}

如您所见，$terminals持有an3ѭ-文档形式如下：

class LocationForm extends Form
{
    public function configure()
    {
        $this->add(new TextField(\'locationName\',array(\'max_length\' => 255,\'required\' => true)));
    }

    public function addTerminals($dm)
    {
        $this->add(new ChoiceField(\'terminals.terminalName\',array(\'choices\' => $dm)));
        $this->add(new DateField(\'terminals.since\',array(\'required\' => true)));
        $this->add(new DateField(\'terminals.to\',array(\'required\' => false)));
    }
}

使用的控制器如下所示：

class LocationController extends Controller
{
    protected $location;
    protected $locationTerminal;

    protected function getDm()
    {
        return $this->get(\'doctrine.odm.mongodb.document_manager\');
    }

    protected function getLocation($name = null)
    {
        if ($name != null)
        {
            $dm = $this->getDm();
            $this->location = $dm->getRepository(\'RalfBundle:Location\')->findOneBy(array(\'locationName\' => $name));
            if (! $this->location)
            {
                $this->location = new Location();
                $this->locationTerminal = new LocationTerminal();
                $this->location->setLocation($name);
                $this->location->setTerminals($this->locationTerminal);
            }
        }
        else
        {
            $this->location = new Location();
            $this->locationTerminal = new LocationTerminal();
            $this->location->setTerminals($this->locationTerminal);
            $this->locationTerminal->setSince(0);
            $this->locationTerminal->setTerminalName(\"\");
            $this->locationTerminal->setTo(0);
        }
    }


protected function getForm()
{
    $form = LocationForm::create($this->get(\'form.context\'),\'location\');
    $dm = $this->getDm();
    $form->addTerminals($dm->getRepository(\'RalfBundle:Terminal\')->findAll()->toArray());
    return $form;
}


//... some Actions

    public function createAction()
    {
        $this->getLocation();
        $form = $this->getForm();

        $form->bind($this->get(\'request\'),$this->location);

        if ($form->isValid())
        {
            $dm = $this->getDm();
            $dm->persist($this->location);
            $dm->flush();
            return $this->redirect($this->generateUrl(\'Location\'));
        }
        return $this->render(\'RalfBundle:Ralf:location_create.html.twig\',array(\'form\' => $form));
    }

我可以看到，ѭ6cie接受了表单中的输入值，但是EmbedMany-Arrayterminals仍然为空。我怎么了感谢您的帮助：D 更新：好的，找到了解决方案。在public function addTerminals($dm)中的public function addTerminals($dm)中，它应如下所示：

public function addTerminals($dm)
{
    $this->add(new ChoiceField(\'terminals.0.terminalName\',array(\'choices\' => $dm)));
    $this->add(new DateField(\'terminals.0.since\',array(\'required\' => true,\'type\'=> \'timestamp\')));
    $this->add(new DateField(\'terminals.0.to\',array(\'required\' => false,\'type\' => \'timestamp\')));
}

\'type\' => \'timestamp\'是必需的，因为DateField将创建DateTime-Object，但是文档期望Int表示timestamp。 terminals数组中的一个字段可以用普通的点符号访问。
