There is an error and a message who tell me to add cascad persist but if i do that the entry is create twice. The is my code and my error message, sorry for my bad english...
Project entity:
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\UserRepository")
* #ORM\Table(name="`user`");
*/
class User implements UserInterface, \Serializable
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=100, nullable=true)
*/
private $firstname;
/**
* #ORM\Column(type="string", length=100, nullable=true)
*/
private $lastname;
/**
* #ORM\ManyToOne(targetEntity="App\Entity\Role")
* #ORM\JoinColumn(nullable=false)
*/
private $role;
Role Entity:
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="App\Repository\RoleRepository")
*/
class Role
{
/**
* #ORM\Id()
* #ORM\GeneratedValue()
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", length=100, unique=true)
*/
private $name;
/**
* #ORM\Column(type="string", length=100, unique=true)
*/
private $code;
/**
* #ORM\OneToMany(targetEntity="App\Entity\User", mappedBy="role")
*/
private $users;
Fixtures file:
<?php
namespace App\DataFixtures;
use Faker\Factory;
use App\Entity\Tag;
use App\Entity\Role;
use App\Entity\User;
use App\Entity\Skill;
use App\Entity\Follow;
use App\Entity\Statut;
use App\Entity\Techno;
use App\Entity\Comment;
use App\Entity\Project;
use App\Entity\Request;
use App\DataFixtures\Provider;
use Faker\ORM\Doctrine\Populator;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Common\Persistence\ObjectManager;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
class AppFixtures extends Fixture
{
public function load(ObjectManager $manager)
{
$generator = Factory::create('fr_FR');
// Ajout provider custom Provider
$generator->addProvider(new Provider($generator));
$populator = new Populator($generator, $manager);
// REMPLIT LES TABLES SIMPLES
// table "role"
$populator->addEntity(
Role::class,
2,
[
'name' => function () use ($generator) {
return $generator->unique()->randomElement(['Administrateur', 'Utilisateur']);
}
]
);
// table "user"
$populator->addEntity(
User::class,
10,
[
'firstname' => function () use ($generator) {
return ($generator->firstName());
},
'lastname' => function () use ($generator) {
return ($generator->lastName());
},
]
);
And my error message when i load fixtures:
In ORMInvalidArgumentException.php line 105:

Answer 1

Same issue with 1.9 version, so just downgrade :
1/ Remove faker folder in vendor.
2/ Change composer.json from
"fzaninotto/faker": "^1.9"
to
"fzaninotto/faker": "1.8"
3/ Run composer update
--> Breath now...
