undefined method in controller from entity symfony

Question

Hello I try to create an entity when another linked entity is created via a postPersist method but I find myself making this error someone knows why? I can not find the reason.

In ClientAdmin.php like the Sonata Documentation advice to do. Sonata Doc

public function postPersist($client)
{

    if ($client instanceof Client )
    {
        $money = new Money();
        $money->setClient($client);
        $money->setSurname($client->getSurname());
        $money->setFirstname($client->getFirstname());
    }
}

Client.php :

/**
 * @ORM\OneToOne(targetEntity="Money", mappedBy="client", cascade={"persist", "remove"})
 */
protected $money;


/**
 * Set money
 *
 * @param \AppBundle\Entity\Money $money
 *
 * @return Client
 */
public function setMoney(\AppBundle\Entity\Money $money )
{
    $this->money = $money;
}

/**
 * Get money
 *
 * @return \AppBundle\Entity\Money
 */
public function getMoney()
{
    return $this->money;
}

The error :

Solution : Working but nothing is create is the table "Money" so i'm supposed it because I don't persist and flush it but I can't do it in it . :/

Working on Symfony 3.3 with SonataAdmin 3.19

Thanks in advance !

Edit : Solution found :

public function postPersist($client)
{
    $em = $this->getConfigurationPool()->getContainer()->get('doctrine.orm.entity_manager');


    if ($client instanceof Client )
    {
        $money = new Money();
        $money->setClient($client);
        $money->setSurname($client->getSurname());
        $money->setFirstname($client->getFirstname());
        $em->persist($money);
        $em->flush();
    }
}

}

Answer 1

your code is totally wrong.

$this->setMoney(new Money()); }  

this means you call setMoney method of the class ClientAdminController(which is $this)

but ClientAdminController does not have the method setMoney(Money). You have to call it on a Client instance.
