我有一个相当常见的用例，我正在尝试实现它，但在 Symfony Sonata Admin Bundle (ORM) 上遇到了一些问题。我的模型在 Facility 和 Sport 之间建立了关系，该关系基于三个实体类：Sport、Facility 和 SportsFacility。我按照示例http://sonata-project.org/bundles/doctrine-orm-admin/master/doc/reference/form_field_definition.html#advanced-usage-one-to-many并在以下类中定义（相关部分只要）。

class Sport {
    /**
    * Bidirectional - Many facilies are related to one sport
    *
    * @ORM\OneToMany(targetEntity="SportsFacility", mappedBy="sport")
    */
    protected $facilities;
    public function getFacilities() {
        return $this->facilities;
    }

    public function setFacilities($facilities) {
        $this->facilities = $facilities;
        return $this;
    }
}

class Facility {
    /**
    * Bidirectional - Many sports are related to one facility
    *
    * @ORM\OneToMany(targetEntity="SportsFacility", mappedBy="facility")
    */
    protected $sports;
    public function getSports() {
        return $this->sports;
    }

    public function setSports($sportsFacilities) {
        $this->sports = $sportsFacilities;
        return $this;
    }

    public function addSports($sportsFacilities) {
        $this->sports = $sportsFacilities;
        return $this;
    }
}

class SportsFacility {
    /**
     * @var integer $sportsFacilityId
     *
     * @ORM\Column(name="sportsFacilityId", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $sportsFacilityId;

    /**
    * Bidirectional - Many Sports are related to one Facility (OWNING SIDE)
    *
    * @ORM\ManyToOne(targetEntity="Sport", inversedBy="facilities"))
    * @ORM\JoinColumn(name="sportId", referencedColumnName="sportId"))

    */
    protected $sport;
    /**
    * Bidirectional - Many Facilities are related to one Sport (OWNING SIDE)
    *
    * @ORM\ManyToOne(targetEntity="Facility", inversedBy="sports"))
    * @ORM\JoinColumn(name="facilityId", referencedColumnName="facilityId"))
    */
    protected $facility;

    public function getSportsFacilityId() {
        return $this->sportsFacilityId;
    }

    public function setSportsFacilityId($sportsFacilityId) {
        $this->sportsFacilityId = $sportsFacilityId;
        return $this;
    }

    public function getSport() {
        return $this->sport;
    }

    public function setSport($sport) {
        $this->sport = $sport;
        return $this;
    }

    public function getFacility() {
        return $this->facility;
    }

    public function setFacility($facility) {
        $this->facility = $facility;
        return $this;
    }
}

在我的 FacilityAdmin 课程中，我有：

protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add('name')
        ->with('Sports')
            ->add('sports', 'sonata_type_collection', 
                array('by_reference' => false),
                array(
                    'edit' => 'inline',
                    'inline' => 'table',
                ))
        ->end();
}

当我尝试添加新关系时，出现以下错误：“vendor/sonata-project/admin-bundle/Sonata/第 88 行的 AdminBundle/Form/EventListener/ResizeFormListener.php"

终于找到了我们的问题所在；在您的课堂设施中，您为奏鸣曲添加了缺失的方法，但它不应该做您认为应该做的事情（是的，是的）：

class Facility {
    ...
    /**
     * Alias for sonata
     */
    public function addSports($sportFacility) {
        return $this->addSport($sportFacility);
    }
}

我认为是添加新实例到集合addSport()的默认学说生成方法。SportsFacility

这是由于奏鸣曲如何生成添加新实体的方法与学说的做法不同：

//file: Sonata/AdminBundle/Admin/AdminHelper.php
public function addNewInstance($object, FieldDescriptionInterface $fieldDescription) 
{
   ...
   $method = sprintf('add%s', $this->camelize($mapping['fieldName']));
   ...
}

有人遇到了同样的问题，但文档没有发展
