Symfony2 Sonata管理员设置查询sonata_type_collection

Question

Is it possible to set up a query for sonata_type_collection? For example II simply do this now...

        ->add('deal', 'sonata_type_collection',
            array(

                'required' => true,
                'label' => 'product',
            ),
            array(
                'property' => 'product',
                'edit' => 'inline',
                'inline' => 'table',

            ))

This works fine, but the deals that I am showing in the collection have statuses... And I only want to display the deals that have statuses set up to true... How can I do that? Can I set up a query for collection?

The thing is I can do this:

        ->add('deal', null, array(
            'by_reference' => false,
            'class' => 'Mp\ShopBundle\Entity\DailyDeal',
            'query_builder' => $this->modelManager->createQuery('Mp\ShopBundle\Entity\DailyDeal', 'h')
                ->where('h.status = 1'),
        ), array(
            'edit' => 'inline',
            'inline' => 'table',
        ))

And this way if is select multiple deals it saves in an array... I want to create a seperate object for every deal I select. Like the sonata_type_collection does..

What could I do?

The only way that I know is to create a property and getter in your Entity that only return your desired values and use it in your Admin class.

Entity.php

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

class Entity
{
   /**
    * @ORM\OneToMany(targetEntity="XXX")
    */
    private $dealsActivated;

    public function getDealsActivated()
    {
         $collection = new ArrayCollection();
         foreach ($this->getDeal() as $deal) {
             if ($deal->getStatus() === 1) {
                 $collection->add($deal);
             }
         }

         return $collection;
    }
}

Admin.php

->add('dealsActivated', 'sonata_type_collection',
    array(

        'required' => true,
        'label' => 'product',
    ),
    array(
        'property' => 'product',
        'edit' => 'inline',
        'inline' => 'table',

    )
)

It's not optimized but works with Sonata.
