使用下一个版本在faker上坚持两次

Question

我在symfony项目中使用fzaninotto/faker的fixture上遇到问题，我有一些关系为ManyToOne的表，由于我在composer上更新了捆绑包，所以在我加载fixture时无法自动完成。

有一个错误和一条消息告诉我添加cascad持久存在，但如果我这样做，条目将创建两次。这是我的代码和错误信息，很抱歉我的英语不好。。。

项目主体：

<?php
namespace AppEntity;
use DoctrineCommonCollectionsArrayCollection;
use DoctrineCommonCollectionsCollection;
use SymfonyComponentSecurityCoreUserUserInterface;
use DoctrineORMMapping as ORM;
/**
* @ORMEntity(repositoryClass="AppRepositoryUserRepository")
* @ORMTable(name="`user`");
*/
class User implements UserInterface, Serializable
{
/**
* @ORMId()
* @ORMGeneratedValue()
* @ORMColumn(type="integer")
*/
private $id;
/**
* @ORMColumn(type="string", length=100, nullable=true)
*/
private $firstname;
/**
* @ORMColumn(type="string", length=100, nullable=true)
*/
private $lastname;
/**
* @ORMManyToOne(targetEntity="AppEntityRole")
* @ORMJoinColumn(nullable=false)
*/
private $role;

角色实体：

<?php
namespace AppEntity;
use DoctrineCommonCollectionsArrayCollection;
use DoctrineCommonCollectionsCollection;
use DoctrineORMMapping as ORM;
/**
* @ORMEntity(repositoryClass="AppRepositoryRoleRepository")
*/
class Role
{
/**
* @ORMId()
* @ORMGeneratedValue()
* @ORMColumn(type="integer")
*/
private $id;
/**
* @ORMColumn(type="string", length=100, unique=true)
*/
private $name;
/**
* @ORMColumn(type="string", length=100, unique=true)
*/
private $code;
/**
* @ORMOneToMany(targetEntity="AppEntityUser", mappedBy="role")
*/
private $users;

夹具文件：

<?php
namespace AppDataFixtures;
use FakerFactory;
use AppEntityTag;
use AppEntityRole;
use AppEntityUser;
use AppEntitySkill;
use AppEntityFollow;
use AppEntityStatut;
use AppEntityTechno;
use AppEntityComment;
use AppEntityProject;
use AppEntityRequest;
use AppDataFixturesProvider;
use FakerORMDoctrinePopulator;
use DoctrineBundleFixturesBundleFixture;
use DoctrineCommonPersistenceObjectManager;
use SymfonyComponentSecurityCoreEncoderUserPasswordEncoderInterface;
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());
},
]
);

当我加载固定装置时，我的错误消息是：

In ORMInvalidArgumentException.php line 105:
Multiple non-persisted new entities were found through the given association graph:

for entity: Administrateur. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or conf

Answer 1

1.9版本也有同样的问题，所以只是降级：

1/删除供应商中的faker文件夹。

2/从更改composer.json

"fzaninotto/faker": "^1.9"

至

"fzaninotto/faker": "1.8"

3/运行composer更新

-->现在呼吸。。。
