Can't Create association on Symfony2 - php

Question

I'm trying to create a "OneToMany" bidirectional association in my project but when I execute "doctrine:schema:update" nothing happens.
If I create this association directly from Sequel Pro and run the update schema command, that changes dissapear... :/
The relations is:
- One "id" from Customers Table with many "customer_id" form Control table.
Here is the Customers code:
<?php
namespace Ourentec\CustomersBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* Customers
*
* #ORM\Table()
* #ORM\Entity
*/
class Customers
{
/* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=100)
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="lastname", type="string", length=100)
*/
private $lastname;
/**
* #var string
*
* #ORM\Column(name="address", type="text")
*/
private $address;
/**
* #var string
*
* #ORM\Column(name="phone", type="string", length=100)
*/
private $phone;
/**
* #var string
*
* #ORM\Column(name="pass", type="string", length=100)
*/
private $pass;
/**
* #var string
*
* #ORM\Column(name="tasks", type="text")
*/
private $tasks;
/**
* #var string
*
* #ORM\Column(name="status", type="string", length=100)
*/
private $status;
/**
* #var string
*
* #ORM\Column(name="email", type="string", length=100)
*/
private $email;
/**
* #var \DateTime
*
* #ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* #var string
*
* #ORM\Column(name="location", type="string", length=100)
*/
private $location;
/**
* #ORM\OneToMany(targetEntity="Control", mappedBy="customers")
*/
private $customer_id;
public function __construct()
{
$this->customer_id = new ArrayCollection();
}
And the Control code:
<?php
namespace Ourentec\CustomersBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Control
*
* #ORM\Table()
* #ORM\Entity
*/
class Control
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var integer
*
* #ORM\Column(name="customer_id", type="integer")
*
* #ORM\ManyToOne(targetEntity="Customers", inversedBy="control")
* #ORM\JoinColumn(name="customer_id", referencedColumnName="id")
*/
private $customerId;
/**
* #var integer
*
* #ORM\Column(name="user_id", type="integer")
*/
private $userId;
/**
* #var \DateTime
*
* #ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* #var integer
*
* #ORM\Column(name="seen", type="smallint")
*/
private $seen;
I followed the documentation from this 2 websites
http://symfony.com/doc/current/book/doctrine.html
http://librosweb.es/libro/symfony_2_x/capitulo_8/relaciones_y_asociaciones_de_entidades.html
But I don't know why it does not work..
Any idea will be appreciated :)

Mapping are not correct, I will try to explain how it works.
In Customers entity (you should rename it to Customer, entites names are singular)
/**
* #ORM\OneToMany(targetEntity="Control", mappedBy="customer")
*/
private $controls;
Mapped by option defines field name in the other entity.
/**
* #var integer
*
* #ORM\Column(name="customer_id", type="integer")
*
* #ORM\ManyToOne(targetEntity="Customers", inversedBy="controls")
* #ORM\JoinColumn(name="customer_id", referencedColumnName="id")
*/
private $customer;
Same thing with inversedBy.
In Customers entity you also need to init controls var as an ArrayCollection:
public function __construct()
{
$this->controls = new ArrayCollection();
}
With these mappings schema should be updated correctly.
For more info, check doctrine docs.
