Php 信条可以'；不要删除实体

php doctrine-orm

Php 信条可以'；不要删除实体,php,doctrine-orm,Php,Doctrine Orm,当我试图借助条令删除实体时，我面临例外这是我的密码： if ($id > 0) { $phase = $em->find("Phase", $id); if ($phase instanceof Phase) { $picture = $phase->getPicture(); if ($picture != "") deleteFile($dir . getPhotoSrc($picture));

当我试图借助条令删除实体时，我面临例外

这是我的密码：

if ($id > 0) {
    $phase = $em->find("Phase", $id);
    if ($phase instanceof Phase) {
        $picture = $phase->getPicture();
        if ($picture != "")
            deleteFile($dir . getPhotoSrc($picture));
        $logo = $phase->getLogo();
        if ($picture != "")
            deleteFile($dir . getPhotoSrc($logo));
        $logo2 = $phase->getLogo2();
        if ($picture != "")
            deleteFile($dir . getPhotoSrc($logo2));
        $em->remove($phase);
        $em->flush();
    }
}

这就是我得到的错误

在课堂计划中，我有：

/**
 * @ManyToMany(targetEntity="Phase", inversedBy="plans", cascade={"persist", "remove"}, fetch="EXTRA_LAZY")
 * @JoinTable(name="links_plan_phase",
 *      joinColumns={@JoinColumn(name="plan_id", referencedColumnName="id")},
 *      inverseJoinColumns={@JoinColumn(name="phase_id", referencedColumnName="id")}
 *      )
 **/
protected $phases;

在课堂阶段，我有：

/**
 * @ManyToMany(targetEntity="Plan", mappedBy="phases", cascade={"persist", "remove"}, fetch="EXTRA_LAZY")
 **/
private $plans;

我终于糊涂了。有谁能帮我找到问题所在以及如何解决问题。
