Question

I try use JMSSerializerBundle I updated my composer, added bundle in my AppKernel.
And I writed this

namespace Surgery\PatientBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;


class VisitsController extends Controller{

    public function testAction()
    {       
        $arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
        $serializer = $container->get('jms_serializer');
        $serializer->serialize($arr, 'json');

And i get this

Call to a member function get() on a non-object

Any idea what I did wrong or I did’t ?

Answer 1

$container is not initialized. It’s a null. You need to get the container from

$this->container->get('jms_serializer');
