Symfony 3 relation not working with update --force - symfony

Question

So, my problem is when I'm trying to update schema with command "dotrine:schema:update --force", entity are create but without any relation.
I have two entity "advert" and "category" and a relation ManyToMany on advert entity.
This is entyty advert :
<?php
namespace testBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* Advert
*
* #ORM\Table(name="advert")
* #ORM\Entity(repositoryClass="testBundle\Repository\AdvertRepository")
*/
class Advert
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="categories", type="string", length=255)
* /**
* #ORM\ManyToMany(targetEntity="OC\PlatformBundle\Entity\Category", cascade={"persist"})
*/
private $categories;
public function __construct()
{
$this->date = new \Datetime();
$this->categories = new ArrayCollection();
}
// Notez le singulier, on ajoute une seule catégorie à la fois
public function addCategory(Category $category)
{
// Ici, on utilise l'ArrayCollection vraiment comme un tableau
$this->categories[] = $category;
}
public function removeCategory(Category $category)
{
// Ici on utilise une méthode de l'ArrayCollection, pour supprimer la catégorie en argument
$this->categories->removeElement($category);
}
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set categories
*
* #param string $categories
*
* #return Advert
*/
public function setCategories($categories)
{
$this->categories = $categories;
return $this;
}
/**
* Get categories
*
* #return string
*/
public function getCategories()
{
return $this->categories;
}
}
My entity category :
<?php
namespace testBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Category
*
* #ORM\Table(name="category")
* #ORM\Entity(repositoryClass="testBundle\Repository\CategoryRepository")
*/
class Category
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* #param string $name
*
* #return Category
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
}
and this is the result of command doctrine:schema:update --force --dump-sql :
CREATE TABLE advert (id INT AUTO_INCREMENT NOT NULL, categories VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB;
CREATE TABLE category (id INT AUTO_INCREMENT NOT NULL, name VARCHAR(255) NOT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB;
Like you can see, no relation and no table advert_category
I found some topic about this but no solution working for me.
I hope someone can help me
Thank you !

Answer 1

Relation declared wrong, i think it should be something like this :
/**
* #ORM\ManyToMany(targetEntity="testBundle\Entity\Category")
* #ORM\JoinTable(name="advert_category")
*/
private $categories;

Answer 2

So problem fixed, I have to delete this :
*
* #ORM\Column(name="categories", type="string", length=255)
/**
and it's work , thank you #thomas !
