如何从现有的数据库数据中生成Symfony fixture YML？

composer require --dev doctrine/doctrine-fixtures-bundle

// src/DataFixtures/UserFixtures.php

namespace App\DataFixtures;

use App\Entity\User;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;

class UserFixtures extends Fixture
{
    public function load(ObjectManager $manager)
    {
        // 从现有的数据库数据中获取用户数据
        $users = $manager->getRepository(User::class)->findAll();

        // 遍历用户数据并生成YML文件
        foreach ($users as $user) {
            $this->addReference('user-' . $user->getId(), $user);
        }
    }
}

# src/DataFixtures/UserFixtures.yml

App\DataFixtures\UserFixtures:
    user-1:
        id: 1
        username: john_doe
        email: john.doe@example.com
        password: $2y$13$lYL/M/L6JvEkxTjW8Jzj.eZXoZv0QWQX/yXUjz0jVpJfKvW
        roles: [ROLE_USER]
    user-2:
        id: 2
        username: jane_doe
        email: jane.doe@example.com
        password: $2y$13$lYL/M/L6JvEkxTjW8Jzj.eZXoZv0QWQX/yXUjz0jVpJfKvW
        roles: [ROLE_USER]

php bin/console doctrine:fixtures:load
