Question

我用MongoDB作为DB创建了一个小的Symfony2-Website（带有Symfony PR11）。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？

这是文件：

/**
 * @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;
    }

}

正如您所看到的，$terminals拥有EmbedMany - 文件这是表格：

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)));
    }
}

使用过的Controller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，locationName收到表单中输入的值，但EmbedMany - 数组terminals仍为空。我错了什么？

感谢您的帮助：D

好的，找到了解决方案。

public function addTerminals($dm) LocationForm中的

应该如下所示：

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'是必要的，因为DateField会创建一个DateTime - 对象，但文档需要Int timestamp。
来自terminals - 数组的字段可以通过普通的点符号访问。

Symfony 2实际上为您提供了一种处理表单中嵌入文档的工具：它被称为“collection field type”，它使您能够以父表单的形式嵌入其他表单类型（来自其他嵌入文档）。

它可以配置为允许/禁止添加/删除嵌入文档，实际上非常强大。
