问题描述

在我的 Symfony 项目中尝试更新 (composer update) 后出现错误.

I have an error after having tried an update ( composer update ) in my Symfony project.

我寻找了一个解决方案，我发现有必要修改实体和构造函数中的使用和类型提示......我已经完成了！

I looked for a solution and I found it was necessary to modify the use and the type-hint in the entity and the constructor.. which I have done!

然后，我重新启动了更新，但出现了另一个错误，并且更新没有完全完成.

Then, I restarted an update but a different error occurred and the update was not fully completed.

结果:我的网站已关闭并显示兼容性错误.

Result: my site is down and a compatibility error is displayed.

看这个:

编译错误:AppDataFixturesAppFixtures::load(DoctrineORMEntityManagerInterface $manager) 的声明必须与 DoctrineCommonDataFixturesFixtureInterface::load(DoctrineCommonPersistenceObjectManager $manager) 兼容在 AppFixtures.php 第 8 行`

Compile Error: Declaration of AppDataFixturesAppFixtures::load(DoctrineORMEntityManagerInterface $manager) must be compatible with DoctrineCommonDataFixturesFixtureInterface::load(DoctrineCommonPersistenceObjectManager $manager) in AppFixtures.php line 8`

我不明白，兼容性是什么?

I don't understand, what the compatibility is?

我不知道如何发布我的代码..(控制器、YAML、实体、..)但我得到了尝试.我的项目在 bug 之前就在 GitHub 上，也许它会很有用(如果你需要的话..)

I don't know how to post my code.. ( controllers, YAML, entity, .. ) but I got try. my project is on GitHub before the bug, maybe it can be useful ( if you need..)

这里是我的 AppFixtures.php :

here my AppFixtures.php :

<?php

namespace AppDataFixtures;

use DoctrineBundleFixturesBundleFixture;
use DoctrineORMEntityManagerInterface;

class AppFixtures extends Fixture
{
    public function load(EntityManagerInterface $manager)
    {
        // $product = new Product();
        // $manager->persist($product);

        $manager->flush();
    }
}

推荐答案

在你的基类 Fixture $manager 实例中的 DoctrineCommonPersistenceObjectManager，所以你需要将 EntityManagerInterface 更改为 ObjectManager.您不能在子类中覆盖 typehint.

In your base class Fixture $manager instance of DoctrineCommonPersistenceObjectManager, so you need change EntityManagerInterface to ObjectManager. You cannot override typehint in children class.
