Symfony call database from class object

Question

On my symfony project I try to call doctrine from a class object, the idea is to put information into the database from the constructor of the object.

First, I must check if the object is already in the database, and if not, I must create the object and add it into the data base. I do this from the class object because a lot a information are done in a single loop, and for optimization, I would like to do it from the object.

My object:

/** class object */
use MainBundle\Services\UserService;
use MainBundle\Entity\Item;
use MainBundle\Entity\User;
use Doctrine\ORM\Mapping as ORM;

class MyListObject{
    function MyListObject($data,$bddUser=null){
        if ($data->getSuccess()){
            foreach($data->getIdItem() as $id){
                $item = new IntItem($id,$data,$this);

                //database stuff
                $repository = $this->get('service.item');//get the table user from the database
                $existItem = $repository->getItemById($id);//get the item

                if ($existItem == null){
                    $itemBdd = new Item();
                    $itemBdd->setIditem($item->getId());
                    $itemBdd->setIdfull($item->getClassIdFull());
                    $itemBdd->setName($item->getName());


                }

My service:

services:
    service.item:
        class: MainBundle\Services\ItemService
        arguments: ['@doctrine.orm.default_entity_manager']

My service class:

<?

class ItemService
{

    private $entityManager;

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

    /*
     * @param integer $blogId
     *
     * @return Blog
     */
    public function getItemById($itemId)

        return $this->entityManager
                    ->getRepository('MainBundle:Item')
                    ->find($itemId);
    }
}

Then I got this error:

Attempted to call an undefined method named "get" of class "MainBundle\Object\MyListObject".

And after that I want to call doctrine again from my object to add the item to the database. I really don't know how I can fix that. all the injections I try haven't worked, I also try to extends controller, but I get another error.

Thanks. be nice with my english please, I have try my best !

I really don't know where I go wrong

your class should extend class ContainerAware

use \Symfony\Component\DependencyInjection\ContainerAware;

class MyListObject extends ContainerAware
{
    public function someMethod() 
    {
        $this->container->get('service.item');
        ...
    }
}

like so you'll have access to the container and all its services.

this time I got this error : Error: Call to a member function get() on a non-object

I already place it into a function. I am using symfony 3 so the ContainerAware is not avalable anymore. I use

use Symfony\Component\DependencyInjection\ContainerAwareInterface; use Symfony\Component\DependencyInjection\ContainerAwareTrait;

that and also I implements ContainerAwareInterface and add a use use ContainerAwareTrait; inside the class

Whith symfony 3

use Symfony\Component\DependencyInjection\ContainerInterface
use Symfony\Component\DependencyInjection\ContainerAwareInterface;   

class ItemService implements ContainerAwareInterface
   {
       private $container;

       public function setcontainer(containerinterface $container = null)
       {
           $this->container = $container;
       }
   }
