I want to pass some data to JavaScript but i got empty vars like this

var testsCompany = {};

var testparams = "[{}]";

It is some issue related of lazy data loading in doctrine, i tried to change the fetch attribute value in ManyToOne association but in vain.

This is my code:

  <script type="text/javascript">

    var testsCompany = "{{ testsCompany|json_encode()|raw}}";

    var testparams = "{{ testparams|json_encode()|raw}}";

  </script>

This is my entity:

class TestParams

{

    /**

     * @var int

     *

     * @ORMColumn(name="id", type="integer")

     * @ORMId

     * @ORMGeneratedValue(strategy="AUTO")

     */

    private $id;



    /**

     * Many testparams have One test.

     * @ORMManyToOne(targetEntity="Tests", inversedBy="testparams",fetch="EAGER")

     * @ORMJoinColumn(name="test_id", referencedColumnName="id")

     */

    private $test;





    /**

     * Many testparams have One param.

     * @ORMManyToOne(targetEntity="Params", inversedBy="testparams", fetch="EAGER")

     * @ORMJoinColumn(name="param_id", referencedColumnName="id")

     */

    private $param;



    /**

     * @var bool

     *

     * @ORMColumn(name="required", type="boolean")

     */

    private $required;



    public function __construct()

    {

        $this->test = new ArrayCollection();

        $this->param = new ArrayCollection();

    }



    public function __toString()

    {

        return '*';

    }



}

and this is the controller code:

/**

     * @Route("/generate/{id}", name="prestashoptest_db_generate")

     */

    public function generateAction(Request $request)

    {

        $testId = $request->get('id');

        $testRepo = $this->getDoctrine()->getRepository('PrestaShopTestBundle:Tests');

        $testParamsRepo = $this->getDoctrine()->getRepository('PrestaShopTestBundle:TestParams');

        $testParams = $testParamsRepo->findBy(array("test" => $testId));

        $testsCompany = $testRepo->find($testId);



        return $this->render('PrestaShopTestBundle:BOTest:generate.html.twig',

            array(

                "testsCompany" => $testsCompany,

                "testParams" => $testParams,

            )

        );

    }

Finally i have a solution:

1. 
   

   I installed a serializer:

   
   
   

   composer require jms/serializer-bundle

   
   



2. configure it :

After you have installed the package, you just need to add the bundle to your AppKernel.php file:

new JMSSerializerBundleJMSSerializerBundle(),

3. and combine twig helpers:

 <script type="text/javascript">

 var testsCompany = {% autoescape %}{{ testsCompany|serialize|raw }}{% endautoescape %};

 var testParams =  {% autoescape %}{{  testParams|serialize|raw }}{% endautoescape %};

 </script>
