Error with relationships between entities and setter function - php

Question

I'm from yesterday fighting with this problem, and I don`t find any solution.
I have two entities interrelated as follows:
// src/FEB/UserBundle/Entity/User.php
namespace FEB\UserBundle\Entity;
use FOS\UserBundle\Entity\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="feb_user")
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
public function __construct()
{
parent::__construct();
// tu propia lógica
}
}
Account.php
namespace FEB\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Account
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="FEB\UserBundle\Entity\AccountRepository")
*/
class Account
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* Many-To-Many, Unidirectional
*
* #var ArrayCollection $idusr
*
* #ORM\ManyToMany(targetEntity="\FEB\UserBundle\Entity\User")
* #ORM\JoinTable(name="accounts_users",
* joinColumns={#ORM\JoinColumn(name="account_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="usr_id", referencedColumnName="id")}
* )
*/
private $idusr;
public function __construct() {
$this->idusr = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Set idusr
*
* #param string $idusr
* #return Account
*/
public function setIdusr($idusr)
{
$this->idusr = $idusr;
return $this;
}
/**
* Get idusr
*
* #return integer
*/
public function getIdusr()
{
return $this->idusr;
}
There is no form to be built, since the user does not have to enter any data, only use the setter for this, not the buildForm method in AccountType.
In Account entity , all the setter function work fine except setter of the field related to the User entity, "setIdusr". It throws me this error:
Catchable Fatal Error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, string given, called in C:\xampp\htdocs\FEB\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php on line 528 and defined in C:\xampp\htdocs\FEB\vendor\doctrine\collections\lib\Doctrine\Common\Collections\ArrayCollection.php line 47
How I can fix this?
Thank you in advanced.
Edit: I will try to explain how it should be functioning: When I create a new account, it should automatically create an entry in the relationship table "account_user" with the id of the new account id and user id.

Answer 1

as far as i can see now, in the parent class you're $id is private and than in the child class you're defining it again as protected.
so either don't use the same variable name.
or define it in the parent as protected.

Answer 2

I've already solved!!!,
I had to create a "addUser" method in Account entity and then I had to pass a User object parameter.
I was passing a string as parameter and that was the error.
