Sonata Admin - Bug with ManyToMany with self referencing ? - SF 2.1

[EnergieZ]

Hi,

I think their is a bug in sonata admin with the manytomany association.

Using, Symfony 2.1 DEV with master branch of sonata.

The goal is to select a related product, using the "list" option (so we can use the filters to find our product).

Trying to use sonata_type_collection, sonata_type_model, or sonata_type_model_list, and still having the problem.

Here is the code i'm using : 

/// Product Entity ///

class Product

{ 

      

    public function __toString() 

    {

        return $this->nom;

    }

    public function __construct()

    {

        $this->accesoires = new \Doctrine\Common\Collections\ArrayCollection();

    }

  

    

/**

     * @var ArrayCollection $accesoires

     * @ORM\ManyToMany(targetEntity="Product", inversedBy="accesoiresTo")

     * @ORM\JoinTable(name="Product_accesoire",

     *      joinColumns={@ORM\JoinColumn(name="Product_id", referencedColumnName="id")},

     *      inverseJoinColumns={@ORM\JoinColumn(name="accesoire_id", referencedColumnName="id")}

     *      )

     */

    private $accesoires;

    

    /**

     * @ORM\ManyToMany(targetEntity="Product", mappedBy="accesoires")

     */

    private $accesoiresTo;

/**
     * Add accesoires
     *
     * @param Cyberl\ApcBundle\Entity\Product $accesoires
     * @return Product
     */
    public function addProduct(\Cyberl\ApcBundle\Entity\Product $accesoires)
    {
        $this->accesoires[] = $accesoires;
        return $this;
    }
    /**
     * Get accesoires
     *
     * @return Doctrine\Common\Collections\Collection 
     */
    public function getAccesoires()
    {
        return $this->accesoires;
    }    
    
    /**
     * Add accesoireTo
     *
     * @param Cyberl\ApcBundle\Entity\Product $accesoire
     * @return Product
     */
    public function addAccesoireTo(\Cyberl\ApcBundle\Entity\Product $accesoireTo)
    {
        $this->accesoiresTo[] = $accesoireTo;
        return $this;
    }
    /**
     * Get accesoiresTo
     *
     * @return Doctrine\Common\Collections\Collection 
     */
    public function getAccesoiresTo()
    {
        return $this->accesoiresTo;
    }  

///////// ADMIN CLASS ///////

 

class ProductAdmin extends Admin
{
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
        ->with('Test')
            ->add('accesoires' , 'sonata_type_model_list', 
                array(
                    'label' => 'Accesoires associés',
                    'by_reference' => true
                ) 
           )
        ->end()
....

Errors i'm getting :

o entity manager defined for class Doctrine\ORM\PersistentCollection

(same error with by reference set to false, and with sonata_type_model instead of sonata_type_model_list)

With this admin class :

->add('accesoires' , 'sonata_type_collection', 
                array(
                    'label' => 'Accesoires associés',
                    'by_reference' => true
                )

 I have this error : 

INVALID MODE : s50377f83ef8fc_accesoires - type : sonata_type_collection - mapping : 8 

(same error with by_reference set to false)

Any solution ?

Thanks for your help.

Hi there,

the sonata_type_model_list doesn't accept a collection as property.

You need to use a sonata_type_model with multiple as true.
