未定义索引：尝试定义两个实体之间的多个关系时使用inverseJoinColumns

Question

我有两个实体：用户和公司，它们之间的关系是n：m。在我的user.php实体中，我有以下代码：

/**
 * @ORM\ManyToMany(targetEntity="PL\CompanyBundle\Entity\Company", mappedBy="users", cascade={"all"})
 */
protected $companies;

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

public function setCompanies(\PL\CompanyBundle\Entity\Company $companies) {
    $this->companies = $companies;
}

public function getCompanies() {
    return $this->companies;
}

/**
 * @ORM\ManyToMany(targetEntity="Application\Sonata\UserBundle\Entity\User", mappedBy="companies")
 */
protected $users;

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

映射出了什么问题？

编辑重构代码

根据@Ahmed-Siouani的指示，我做了以下更改：

/**
 * @ORM\ManyToMany(targetEntity="PL\CompanyBundle\Entity\Company", inversedBy="users")
 * @ORM\JoinTable(name="fos_user_user_has_company",
 *      JoinColumns={@ORM\JoinColumn(name="fos_user_user_id", referencedColumnName="id")},
 *      inverseJoinColumns={@ORM\JoinColumn(name="company_id", referencedColumnName="id")}
 * )
 */
protected $companies;

/**
 * @ORM\ManyToMany(targetEntity="Application\Sonata\UserBundle\Entity\User", mappedBy="companies")
 */
protected $users;

Answer 1

在定义jointable时，可能需要指定joincolumns和inversejoincolumns。因为双向多对多定义是类似的，

class User
{
    // ...

    /**
     * Bidirectional - Many users have Many companies (OWNING SIDE)
     *
     * @ManyToMany(targetEntity="Company", inversedBy="users")
     * @JoinTable(name="users_companies",
     *     joinColumns={@ORM\JoinColumn(name="user_id", referencedColumnName="id")},
     *     inverseJoinColumns={@ORM\JoinColumn(name="company_id", referencedColumnName="id")}
     * )
     **/
    private $companies;

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

    // ...
}

虽然您的Company类应定义如下,

class Company
{
    // ...

    /**
     * Bidirectional (INVERSE SIDE)
     *
     * @ManyToMany(targetEntity="User", mappedBy="companies")
     */
    private $users;
