Symfony2表单映射问题

Question

Im having issues with data mapping to an entity after it is submitted

The form is:

class UserAddressType extends AbstractType

    {
        $builder
            ->add('UserId','hidden')
            ->add('LevelId', 'integer', array(
                    'label'=>'Sort Rate (Order)'
                ))
            ->add('AddressTypeId', 'entity', array(
                    'class'=>'SiteUserBundle:UserAddressType',
                    'query_builder'=> function(EntityRepository $er){
                            return $er->createQueryBuilder('t')
                            ->orderBy('t.AddressDescription', 'ASC');                        
                        },
                    'property'=>'AddressDescription',
                    'label'=>'Address Type'
                ))
            ->add('AddressData', 'text')
            ->add('PublicYN', 'choice', array(
                    'choices' => array( 'false'=>'Private', 'true'=>'Public'),
                    'required'=>true,
                    'label'=>'Pubicly Visable'
                ))
            ->add('PrimaryYN', 'choice', array(

                            'class'=>'btn btn-primary',
                        ),
                  ))
        ;
    }

    /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Site\UserBundle\Entity\UserAddress',
            'csrf_protection'=>false,
        ));
    }

    /**
     * @return string
     */
    public function getName()
    {
        return 'Create_User_Address';
    }
}

Controller Function is: (I'm using fosrestbundle)

public function newAddressAction($userid, Request $request)
    {

        $statusCode = 201;
        $address = new UserAddress();
        $address->setUserId($userid);

        $form = $this->createForm( new UserAddressType(), $address, array(
                'method'=>'GET',
            ));
        $form->handleRequest($request);

        if($form->isValid()){
               $em = $this->getDoctrine()->getManager();
               $em->persist($address);
               $em->flush();
               return new Response('User Added to system');
        }        
        return $this->render('SiteUserBundle:UserAddress:newUserAddress.html.twig', array(
            'form' => $form->createView(),

)); }

The Twig template is very simple. All the data is posted correctly to the server: (Query String Parameters )

Create_User_Address[LevelId]:0
Create_User_Address[AddressTypeId]:5
Create_User_Address[AddressData]:555-555-5555
Create_User_Address[PublicYN]:false
Create_User_Address[PrimaryYN]:false
Create_User_Address[save]:
Create_User_Address[UserId]:3

but i keep getting the following error:

An exception occurred while executing 'INSERT INTO user_address (user_id, level_id, address_type_id, address_data, public_yn, primary_yn) VALUES (?, ?, ?, ?, ?, ?)' with params [null, 0, null, "555-555-5555", "false", "false"]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'user_id' cannot be null

As you can see the UserID and AddressTypeId fields are not mapping from the form to the Entity. I have looked over the code for all 3 pieces over and ove and for the life of me i can't see where the mismatch is happening. I did at one point change the names of those two fields in the Entity but i deleted all the getters and setters and regenerated them as well as clear the dev cache.

My hunch is there is a file somewhere in Symfony2 there is a mapping class that is wrong but i can't find it..

Thanks all

EDIT:

I tried clearing the doctrine cache as stated here: Symfony2 doctrine clear cache .

app/console doctrine:cache:clear-metadata 
app/console doctrine:cache:clear-query  
app/console doctrine:cache:clear-result

this resulted in the same error being generated,so the cache issue may be off the table.

EDIT:

As per Isaac's suggestion i removed ->add('UserId', 'hidden') . The form still posted with the same error message. The field is being generated correctly to the page; <input type="hidden" id="Create_User_Address_UserId" name="Create_User_Address[UserId]" class=" form-control" value="3"> and as you can see from the Query Parameters above being posted back to the server correctly.

EDIT:

I tracked the issue down to the User and UserAddressType variables. If i remove these two variables and their getters and setters the form works perfectly without other modifications of my code. I should note that these two variables are joins to other entities. Some how they seem to be wiping out the data being submitted by the forms.

As per lsouza suggestion I had to create a data transformer.

namespace Site\UserBundle\Form\DataTransformer;

use Symfony\Component\Form\DataTransformerInterface;
use Symfony\Component\Form\Exception\TransformationFailedException;
use Doctrine\Common\Persistence\ObjectManager;

use Site\UserBundle\Entity\UserAddressType;

class AddressTypeToNumber implements DataTransformerInterface
{
    /**
     * @var ObjectManager
     */
    private $om;

    /**
     * @param ObjectManager $om
     */
    public function __construct(ObjectManager $om)
    {
        $this->om = $om;
    }

    /**
     * Transforms an object(val) to a string
     * 
     * @param UserAddressType|null $val
     * @return string
     */
    public function transform($val)
    {
        if (null === $val) {
            return "";
        }

        return array();
    }

    /**
     * Transfers a string to an object (UserAddressType)
     * 
     * @param string $val
     * @return UserAddressType|null 
     * @throws TransformationFailedException if object is not found
     */
    public function reverseTransform($val)
    {
        if (!$val) {
            return null;
        }

        $addId = $this->om
            ->getRepository('SiteUserBundle:UserAddressType')
            ->findOneBy(array('AddressTypeId' => $val));  

         if (null === $addId) {
             throw new TransformationFailedException(sprintf(
                'An Address Type with the ID of "%s" does not exsist in the system',
                $val
             ));
         }

        return $addId;
    }
}

Please note that the Transformer function is currently returning null but this should return a value that can be used by the form.

Some other notes that may help others are that the form class needs to be changed as well.

The setDefaultOptions function needs the following added to the $resolver variable:

    ->setRequired(array(
        'em',
    ))
    ->setAllowedTypes(array(
        'em'=>'Doctrine\Common\Persistence\ObjectManager',
    ));

The buildForm function needs to be changed slightly to accept the em option:

public function buildForm(FormBuilderInterface $builder, array $options)
{
   $em = $options['em'];
   $transformer = new AddressTypeToNumber($em);

The field needs to be change to the varrable that holds the relationship in the Entity and not the field that is use in the link:

    ->add(
        $builder->create('UserAddressType', 'entity', array(
            'class' => 'SiteUserBundle:UserAddressType',
            'property' => 'AddressDescription',
            'label' => 'Address Type'
        ))
        ->addModelTransformer($transformer)
    )

Finally in your controller you need to pass an instance of $this->getDoctrine()->getManager() to the form class:

$form = $this->createForm( new UserAddressType(), $address, array(
    'em' => $this->getDoctrine()->getManager(),
));

I hope this helps others.
