Php 具有稍微相似实体的不同行为

我用Symfony2制作了一个web应用程序。有两种用户，

UserOperator

和

UserGroundStation

。它们都扩展了

        {
            $this->addRole('ROLE_GS');

    }

用户操作员

它们扩展了

用户

当我为

UserOperator

调用注册页面时，它会工作；当我为

UserGroundStation

调用注册页面时，Symfony会提醒我：

属性“mission”或方法“getMission（）”、“isMission（）”、“hasMission（）”、“\uu get（）”中的任何一个都不存在，并且在类“Acme\ManagementBundle\Entity\UserGroundStation”中都没有公共访问权限

怎么可能呢？我在哪里可以找到错误

使用者

这真是个愚蠢的问题

它们有不同的表单类型：

RegistrationUserOperatorFormType不同于RegistrationUserGroundStationFormType和

---

ProfileUserGroundStationFormType与ProfileUserOperatorFormType不同。

您应该发布

User

类的内容；听上去，您没有正确实现多关系所需的接口。过去，我在扩展基本实体时遇到了许多问题。尝试将这些方法也放在

UserGroundStation

中。至少带有

parent:：method（）

的方法在它们内部调用，只是为了看看这是否是层次结构问题。
