在具有最接近版本的伪造者上坚持两次

Question

我在symfony项目中使用fzaninotto / faker的灯具存在问题，我有一些表与ManyToOne的关系，由于我在composer上有更新包，因此在加载灯具时它们不会自动完成。

存在错误，并且有一条消息告诉我添加级联，但是如果我这样做，则该条目将创建两次。这是我的代码和错误消息，抱歉我的英语不好...

        // table "user"
        $populator->addEntity(
            User::class,
            10,
            [
                'firstname' => function () use ($generator) {
                    return ($generator->firstName());
                },
                'lastname' => function () use ($generator) {
                    return ($generator->lastName());
                },
            ]
        );

以及我在加载灯具时的错误消息：

In ORMInvalidArgumentException.php line 105:

   * A new entity was found through the relationship 'App\Entity\User#role' that was not configured to cascade persist operations
