为什么总是以带字段日期的形式为null？ （在symfony2中）

Question

I have a problem with Form in Symfony2,

This is mi form Code:

 $form = $this->createFormBuilder($pedido)
            ->setAction($this->generateUrl("ec_main_guardar_pedido"))
            ->add('cliente','entity',array('class' =>'ECMainBundle:Clientes','property'=>'cliente'))
            ->add('fecha', 'date', array('widget' => 'single_text',
                                         'format' => 'd-M-y',
                                         'required' => 'false',
                                         'read_only' => 'false'))
            ->add('fentrega', 'date',array('format' => 'yyyy-MM-dd'))
            ->add('estado','hidden', array('data' => '3'))
            ->add('Guardar', 'submit')
            ->getForm();

The field 'fecha' don't work, i test with another formats, but i dont have solution, always say 'null', i try to generate the javascript to show one calendar, but the problem is the same, always null.

If in the Entity add this:

public function __construct()
    {
        $this->lineas = new ArrayCollection();
        $this->fecha= new \DateTime();
        $this->fentrega= new \DateTime();
    }

the field 'fecha' always is today.

And the field 'fentrega' with the widget choise work perfect.

Anyone can helpme please?

Thanks in advance.

Well, now work perfect, the problem is the format of the date.

With this code work correct:

the controller:

$form = $this->createFormBuilder($pedido)
            ->setAction($this->generateUrl("ec_main_guardar_pedido"))
            ->add('cliente','entity',array('class' => 'ECMainBundle:Clientes','property'=>'cliente'))
            ->add('fecha', 'date', array('widget' => 'single_text',
                                         'format' => 'd-M-y'))
            ->add('fentrega', 'date',array('format' => 'yyyy-MM-dd'))
            ->add('estado','hidden', array('data' => '3'))
            ->add('Guardar', 'submit')
            ->getForm();

in the view:

$('#form_fecha').datepicker({
            dateFormat : 'd-m,-yy',
            prevText : '<i class="fa fa-chevron-left"></i>',
            nextText : '<i class="fa fa-chevron-right"></i>',

        });

the problem is 'format' => 'dM-y') is equal to dateFormat : 'd-mm-yy' the reason... i don't know...

Thanks all for the help

Do not use __construct() to set default data. After object is created (by __construct) Doctrine do its magic and override values set by a constructor. Prepare method setDefauts() and put setting default data there. Then, after created model, ie. in controllers action run this method.

// /Acme/FooBundle/Entity/Bar.php
// ...
public function setDefaults()
{
    $this->fecha = new \DateTime();
    $this->fentrega = new \DateTime();
}
// ...


// /Acme/FooBundle/Controller/BarController.php
// ...
public function someAction()
{
    $var = new Bar();
    $var->setDefaults();
}
// ...
