【问题描述】：

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。我遵循示例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（仅相关部分）。

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/AdminBundle/Form/EventListener/ResizeFormListener.php 第 88 行”中给出的“数组或\​​Traversable”类型的预期参数、“Clarity\CoachTimeBundle\Entity\SportsFacility”

【问题讨论】：

你确定在 SportsFacility 类的注解上关闭 @ORM\ManyToOne(targetEntity="Sport", inversedBy="facilities")) 的额外 ")" 吗？

我也有这个问题（但我在关系实体中添加了is_active）。我看到很多人使用这个kind of solution 它可能对你有用（部分在我的情况下）

您找到解决问题的方法了吗？我有一个类似的问题：***.com/questions/15629225/…

您能添加您的 SportFacilityAdmin 吗？我不了解这里通常使用的技巧：* @ORM\OneToMany(targetEntity="SportsFacility", mappedBy="facility") */ protected $sports;你称它为 $sports，其实它应该是 $sportsFacilieties

【参考方案1】：

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addSport() 是默认的学说生成方法，用于将SportsFacility 的新实例添加到集合中。

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']));
   ...

有人得到了the same problem，但文档没有发展
