Question

我不明白......

致命错误：未捕获的Doctrine \ ORM \ Mapping \ MappingException：The 目标实体商店无法在＆＃39;用户#shop＆＃39;中找到。在

我只有一个User课程。

/**
 * @Entity
 **/
class User
{

    /** @Id
     * @Column(type="integer")
     * @GeneratedValue
     **/
    protected $id;

    /**
     * @OneToMany(targetEntity="Shop", mappedBy="user")
     */
    protected $shops;

    public function __construct()
    {
        $this->shops = new \Doctrine\Common\Collections\ArrayCollection();
    }
}

谁拥有多个Shop s。

/**
 * @Entity
 */
class Shop
{

    /** @Id
     * @Column(type="integer")
     * @GeneratedValue
     **/
    protected $id;

    /**
     * @ManyToOne(targetEntity="User", inversedBy="shops")
     */
    protected $user;
}

它们位于同一目录中，因此不是namespace问题吗？

Getters＆amp;已经生成的Setters很好，但仍然没有改变。

TIPS ：如果将我的所有课程都放在同一个php文件中，那就可以了！

Answer 1

Provided these are the full files, you are not writing any namespace declarations on the classes. Therefore the Entity classes are put in the \ root namespace.

So to resolve this you will either need to use the FQN (Full Qualified Name) or import the classes.

Using FQN (my recommendation)

/**
 * @OneToMany(targetEntity="\Shop", mappedBy="user")
 */

(add the same in the other class as well)

Using import

Add this on the top of the User class

use \Shop;

(the inverse in the other class of course)

Note: The PHP Interpreter doesn't check for usages in Annotations, so if you don't use the class elsewhere in the file, PHP might show a warning about an unused import if that is enabled.
