当我向实体添加OneToMany关联时，魔术查找器无法工作（Doctrine 2）

Question

在我向我的实体添加OneToMany协会后，魔术查找器以及从数据库获取结果的任何方法都已停止，并且我收到致命错误。

这是第一个实体（Slaplans）：

我尝试使用以下代码获取Slaplans实体时出现致命错误：

$默认= $这 - ＆GT; _em-＆GT; getRepository（ 'ZC \实体\ Slaplans'） - ＆GT; findOneBySlaplanid（$ planid）;

我尝试了queryBuilder，但是当我运行getResult函数时，我也收到错误。

请帮帮我。

Answer 1

对于holidaylinks变量（Slaplans Entity）：

/**
     *
     * @param \Doctrine\Common\Collections\Collection 
     *
     * @OneToMany(targetEntity="Slaholidaylinks",mappedBy="planid", cascade={"persist"})
     */
    private $holidaylinks;

对于planid变量（Slaholidaylinks Entity）：

/**
     *
     * @var Slaplans
     * @ManyToOne(targetEntity="Slaplans",inversedBy="holidaylinks")
     * @JoinColumns({
     *  @JoinColumn(name="slaplanid", referencedColumnName="slaplanid")
     * })
     */
    private $planid;

这就是我解决问题的方法:)
