Doctrine. One to many. How to write annotations?

I have a OneToMany relation between two tables 'user' and 'profil' (a user has one only profile, and a profile can be asseigned to many users) I'm getting this error whenever I try to update the schema in doctrine console.

here is my two entities :

Solution

You have syntax mistake. @ORMManyToOne - this is mistake.
```
@ORM\ManyToOne(targetEntity="Profil", inversedBy="users") 
```
Above will be correct. And everywhere you use ORM You need to write ORM\something. ORM - is just a namespace, or simply path to the ORM classes in doctrine vendor directory!
Every class name should start with capital letter. It is a wright way! So you should write class User, but not class user!
You didn't show in Profil class, that you have a lot of users to each profil. the users field will be of array collection type (simple array but with useful methods.) So in Profil class in __construct() method:
```
public function __construct()
{
    $this->users = new ArrayCollection();
}
```
You have One-To-Many, Bidirectional relation. You can say :
- Every (ONE) profile can have a lot of (MANY) users, which use it (One-To-Many)
- Every user can use only one exact profile

So try this

// Class Profil
    /**
     * Bidirectional - One-To-Many (INVERSED SIDE)
     * One Profile can have many users, which use it
     *
     * @var ArrayCollection $users
     *
     * @ORM\OneToMany(targetEntity="Path-to-your-user-class\Users", mappedBy="profil", cascade={"persist", "remove"}, orphanRemoval=true)
     */
    private $users;

    public function __construct()
    {
        $this->users = new ArrayCollection();
    }


// Class user
    /**
     * Bidirectional - One-To-Many (OWNER SIDE)
     * One user have only one profile (or profil)
     *
     * @var Profil $profil
     *
     * @ORM\ManyToOne(targetEntity="AppBundle\Entity\Profil", inversedBy="users")
     * @ORM\JoinColumn(name="profil_id", referencedColumnName="id")
     */
    private $profil;
