symfony - 带有 Doctrine 树扩展的 Symfony 循环引用异常

Question

我有一个循环引用异常，因为Doctrine Tree Extension当我试图用 Alice 夹具加载我的夹具时。

[Doctrine\Common\DataFixtures\Exception\CircularReferenceException]
图包含循环依赖。此问题的一个示例如下：C 类将 B 类作为其依赖项。然后，B 类有 A 类有它的依赖。最后，A 类将 C 类作为其依赖项。

我在这里发现了同样的问题： https ://github.com/doctrine/data-fixtures/issues/232但该解决方案对我不起作用:( ...

我正在使用这个版本的教义夹具。

"doctrine/data-fixtures": "1.2.1",

这是我的实体
